Some notes on the translation of these original CENTURION operating instructions

The illustrations on the first pages of the translation of these original CENTURION operating instructions show typical CENTURION city/trekking bikes and a typical CENTURION pedelec. One of these CENTURION bikes looks similar to the CENTURION city/trekking bike or CENTURION pedelec you have purchased. Today’s bikes and pedelecs come in various types that are designed for specific uses and fitted accordingly. The translation of these original CENTURION operating instructions includes the following bicycle types:

City, trekking, fitness Pedelecs

In this translation of the original CENTURION operating instructions pedelecs with drive support and described as EPACs in the European standard EN 15194 are referred to as pedelecs. For a precise description of the different EPAC types see the chapter “Intended use”.

In this translation of the original CENTURION operating instructions the term “bicycle” will always be used in general descriptions if this refers to city/trekking bikes and pedelecs.

General safety instructions

Dear CENTURION customer,

In purchasing this CENTURION bike chosen a product of high quality. Each component of your new CENTURION bike has been designed, manufactured and assembled with great care and

expertise. Your CENTURION dealer gave the pedelec its final assembly and adjustment. This guarantees you pleasure and a sense of confidence from the very first turn of the pedals.

This manual contains a wealth of information on the proper use of your CENTURION bike, its maintenance and operation as well as interesting information on bike and pedelec design and engineering. Read this

translation of the original CENTURION operating instructions thoroughly. We are sure that even if you have been cycling all your life you will find useful and detailed information. Bike technology has developed at a rapid pace during recent years

Therefore, before setting off on your new CENTURION bike, be sure to read at least the chapter “Before your first ride”.

To ensure as much fun and safety as possible during cycling, be sure to carry out the functional check described in the chapter “Before every ride” before setting off on your CENTURION bike.

you have

Even a manual as big as an encyclopedia could not describe any possible combination of bicycle or pedelec models and components or parts on the market. The translation of these original CENTURION operating instructions therefore focuses on your newly purchased CENTURION city/trekking bike and CENTURION pedelec and standard components and provides the most important information and warnings. In addition to this, the system instructions of your drive manufacturer give important information and warnings on handling your new CENTURION bike.

When doing any adjusting and maintenance work, be aware that the detailed instructions provided in your manual only refer to this CENTURION bike.

The information included here is not applicable to any other bicycle or pedelec type. As bicycles and pedelecs come in a wide variety of designs with frequent model changes, the routines described may require complementary information. It is essential to also observe the system instructions of your drive manufacturer as well as the instructions of the component manufacturers on this CENTURION CD-ROM.

Be aware that these instructions may require further explanation, depending on the experience and/or skills of the person doing the work. For some jobs you may require additional (special) tools or supplementary instructions. This manual cannot teach you the skills of a bicycle mechanic.

This CENTURION CD-ROM includes the

nent manufacturers as well as the relevant web links.

Before you set off, let us point out a few things to you that are very important to every cyclist. Never

ride without a properly adjusted helmet and without glasses clothing, as a minimum you should wear straight cut trousers and or leg bands and shoes fitting the pedal system and observe the traffic rules so as not to endanger yourself or others.

This manual cannot teach you how to ride. Please

be aware that cycling is a potentially dangerous activity that requires the rider to stay in control of his or her CENTURION bike at all times. Be aware from the moment you set off that you possibly ride at a higher speed course for cyclists, as offered here and there.

Like any sport, cycling involves the risk of injury and damage. By choosing to ride a bike, you assume

the responsibility for the risk. Please note that on a bike you have no protection technique around you like you have in a car (e.g. bodywork, ABS, airbag). Therefore, always ride carefully and respect the other traffic participants.

Never ride under the influence of drugs, medication, alcohol or when you are tired. Do not ride with a second person on your CENTURION bike (except on tandems or with kids in a child seat) and never ride without having both hands on the handlebars (except: hand signals before turning).

Observe the legal regulations concerning off-road cycling and cycling on public roads with CENTURION bikes and CENTURION pedelecs

(e+f)

. These regulations may differ in each country. Respect nature when riding through the forest and in the open countryside. Only use your pedelec on signposted, well maintained trails and hard-surface roads.

Always bear in mind that you travel rapidly and quietly when you are riding a CENTURION pedelec. Do not startle pedestrians or other cyclists. Always make others aware of your presence well ahead of time and by ringing your bell or make use of the brakes so as to avoid accidents. Familiarize yourself with your CENTURION pedelec. For more information see chapter “Riding a CENTURION pedelec – Special features“.

If you bought a CENTURION kids’ bike, observe chapter “CENTURION kids’ bikes“ before your child sets off on it for the first time. There are special traffic regulations for children in some countries. Read the mentioned chapter, before your child sets off on the bike for the first time.

Intended use

Keep in mind that every type of bike is designed for a specific use only for to its intended purpose, otherwise it may not withstand the loads and fail causing an accident with unforeseeable consequences! In addition, if you use your bike for another than its intended purpose, the warranty will become void.

Ask your CENTURION dealer to confirm the category your CENTURION bike belongs to.

CENTURION bikes are suitable for such use. Ask your CENTURION dealer before such a use. If you decide to use your bike in such a way, you voluntarily assume a highly increased injury risk which can even result in death. In addition, your CENTURION bike is exposed to higher loads and you hereby accept a clearly reduced service life of the CENTURION bike.

Pedelecs Pedelecs (pedal electric cycles) or EPACs (Elec-

trically Power Assisted Cycles) are bicycles with an auxiliary motor that only switches on when you move the pedals. When you stop pedaling, the motor switches off.

A driving license is not required for riding a CENTURION pedelec

(e)

, if the motor assistance switches off automatically at a speed of 25 kmh. You do not need an operating license and need not insure the pedelec either.

In general, all regulations that apply to bicycles also apply to CENTURION pedelecs. Inform yourself in the country where you use your CENTURION pedelec whether wearing a helmet is compulsory

(f)

Most CENTURION pedelecs are designed for cycling exclusively on lanes and roads with a smooth surface

(g)

. Only use trails that are allowed for bicycles. For off-road use only CENTURION off-road pedelecs are suitable. Using CENTURION trekking pedelecs off-road can result in crashes with unforeseeable consequences.

Some CENTURION pedelecs have a pushing aid

(h)

which provides assistance during pushing, even without pedaling, up to a speed of 6 kmh.

The maximum permissible additional load (rider plus baggage) is 120 kg. Under certain circumstances the maximum permissible additional load can be further limited by the component manufacturers’ recommendations for use.

and the permitted overall weight (rider, CENTURION bike and baggage) see the bike card and chapter “Before your first ride”.

Before your first ride

1. If you want to use your pedelec on public roads, it has to comply with legal requirements. These requirements may vary in each country. The fittings of your CENTURION bike are, therefore, not necessarily complete

Ask your CENTURION dealer concerning the laws

and regulations applicable in your country or in the country you intend to use your CENTURION bike. Have your CENTURION bike equipped accordingly before using it on public roads.

For more information see the chapter “Legal

requirements for riding on public roads“.

(e)

2. Are you familiar with the brake system Have a look at the bike card and check whether the brake lever of the front brake is on the side you are used to (right or left). If it is not, ask your CENTURION dealer to switch the brake levers before you set off for the first time.

Your new pedelec is equipped with modern

brakes which may be far more powerful than those you were used to so far. Be sure to first practice using the brakes on a level, non-slip surface off public roads! Slowly approach higher brake performances and speeds.

For more information see the chapter “The brake

system” and the instructions of the component manufacturers on this CENTURION CD-ROM.

(f-h)

3. Are you familiar with the type and functioning of the gears explain you the gear system and make yourself familiar with your new gears in an area free of traffic, if necessary.

For more information see the chapter “The gears”

and the instructions of the component manufacturers on this CENTURION CD-ROM.

4. Are saddle and handlebars properly adjusted? The saddle should be set to a height from which you can just reach the pedal in its lowest position with your heel. Check whether your toes reach to the floor when you are sitting on the saddle

help you, if you are not happy with your seating position.

For more information see the chapter “Adjusting

the CENTURION bike to the rider”.

5. If your CENTURION bike is equipped with clipless or step-in pedals the shoes they go with? First practice locking one shoe onto a pedal and disengaging it while standing on the other leg. Ask your CENTURION dealer to explain you the pedals.

For more information see the chapter “The ped-

als and the shoes” and the instructions of the component manufacturers on this CENTURION CD-ROM.

Your CENTURION bike has undergone numerous tests during production and a final check has been carried out by your CENTURION dealer. Nevertheless, be sure to check the following points before every ride to exclude any malfunctioning that may be due to the transport of your CENTURION bike or to

changes a third person may have performed on your CENTURION bike before delivery:

1. Are the quick-release levers nections of the front and rear wheel, the seat post and other components properly closed?

For more information see the chapter “How to

use the quick-releases” and the instructions of the component manufacturers on this CENTURION CD-ROM.

2. Are the tires in good condition and do they have sufficient pressure a better riding stability and reduces the risk of a puncture. The minimum and maximum pressure (in bar or psi) is indicated on the tire side.

3. Spin the wheels to check whether the rims are true. If you have disc brakes, watch the gap between frame and rim or tire and, if you have rim brakes, between brake pad and rim. Untrue rims can be an indication of tires with ruptured sides, broken axles or spokes.

For more information see the chapter “The

wheels and the tires” and the instructions of the component manufacturers on this CENTURION CD-ROM.

4. Test the brakes in stationary by firmly pulling the brake levers towards the handlebars

(a)

. The brake pads of rim brakes must hit the rim evenly with their entire surface without touching the tire during braking or in open condition or in between. Make sure you cannot pull the brake levers all the way to the handlebars and check the hydraulic brake cables for mineral oil/brake fluid leaks! Check the thickness of the brake pads, as well.

With disc brakes you should have a stable

pressure point at once. If you have to actuate the brake lever more than once to get a positive braking response, have the CENTURION bike checked by your CENTURION dealer immediately.

For more information see the chapter “The brake

system” and the instructions of the component manufacturers on this CENTURION CD-ROM.

5. Let your CENTURION bike bounce on the ground from a small height. If there is any rattling, see where it comes from. Check the bearings and bolted connections, if necessary. Tighten them slightly, if necessary.

6. In case you have a CENTURION bike with suspension, press down on your CENTURION bike

8. Do not forget to take a high quality Dchain lock with you on your ride. The only way to effectively protect your CENTURION bike against theft is to lock it to an immovable object.

9. If you want to ride on public roads, make sure your CENTURION bike is equipped according to the applicable regulations of your country Riding without lights and reflectors in dark or dim

conditions is very dangerous because you will be seen too late or not at all by other road users. A lighting set that corresponds to the regulations is a must on public roads. Turn on the lights as soon as dusk sets in.

After an accident

1. Check whether the wheels are still firmly fixed in the drop-outs centered with respect to the frame or fork. Spin the wheels and observe the gap either between brake pads and rim sides or between frame and

tire. If the width of the gap changes markedly and you have no way to true the wheel where you are, you will need to open the rim brake a little by means of the special mechanism so that the rim can run between the brake pads without touching them. Please note that in this case the brakes may not act as powerfully as you are used to.

No matter whether you have rim or disc brakes,

have the wheels trued by your CENTURION dealer immediately after you are back home.

For more information see the chapters “The

brake system”, “How to use the quick-releases” and “The wheels and the tires” as well as in the instructions of the component manufacturers on this CENTURION CD-ROM.

3. Check whether the chain still runs on the chainwheels and the sprockets

(e)

. If your CENTURION bike fell over to the chain side, verify the proper functioning of the gears. Ask somebody to lift your CENTURION bike by the saddle and carefully shift through all the gears. Pay particular attention when switching to the small gears, making sure the rear derailleur does not get too close to the spokes as the chain climbs onto the larger sprockets.

If the rear derailleur or the drop-outs/derailleur

hanger is bent, the rear derailleur may collide with the spokes. This in turn can destroy the rear derailleur, the rear wheel or the frame. Check the function of the front derailleur, as a displaced front derailleur can throw off the chain, thus interrupting the drive of your CENTURION bike.

to detect any deformations, color changes or cracks. Ride back very carefully by taking the shortest route possible, even if your CENTURION bike went through this check without any problems. Do not accelerate or brake hard and do not ride your pedelec out of the saddle. If you are in doubt about the perfor-

mance of your CENTURION bike, have yourself picked up by car, instead of taking any risk.

1. Check the rechargeable battery rechargeable battery is no longer properly in its

holder or shows any damage, do not use your CENTURION pedelec any longer, at least not in the assistance mode. Switch off the drive and the rechargeable battery separately, if necessary. A damaged battery can lead to a short-circuit resulting in a sudden failure of the CENTURION pedelec assistance right at the moment when you need it.

Damage to the outer housing of the recharge-

How to use the quick-releases

Most CENTURION bikes and CENTURION pedelecs are fitted with quick-releases adjustments, assembly and disassembly. Be sure to check whether all quick-releases are tight before you set off on your CENTURION bike. Quick-releases should be handled with greatest care, as they affect

your safety directly.

Practice the proper use of quick-releases to avoid any accidents.

Move the lever back, as if to close it. Now you should be able to read ”Close“ lever. When you start closing the lever you should feel virtually no resistance with your hand until the lever is at a right angle to the frame/fork.

When continuing to close the lever the resistance you feel should increase significantly and towards the end even more strength is required to close the lever. Use the ball of your thumb while your fingers pull on an immovable part, such as the fork not on a brake disc or spoke, to push it in all the way.

In its end position, the lever should be at a right angle

to the quick-release axle out. The lever should lie close to the frame or the fork so that it cannot be opened accidentally. Make sure, however, that the lever is easy to handle for actual quick use.

To check whether the lever is securely locked apply pressure to the end of the hand lever and try to turn it while it is closed. If you can turn the lever around, open it and increase the preload. Screw the tightening nut on the opposite side clockwise by half a turn. Close the quick-release lever and check it again for tightness.

Finally lift the pedelec a few centimeters, so that the wheel no longer touches the ground, and hit the tire from above. If it is properly fastened, the wheel will remain firmly fixed in the drop-outs of the frame or fork without producing any rattling.

If your seat post is equipped with a quick-release mechanism, check whether the saddle is firmly fixed by trying to twist it relative to the frame.

do not hurt yourself when you have to get off your pedelec quickly.

By choosing a specific type of bike you roughly determine the posture you will be riding in some components of your CENTURION bike are especially designed so that you can adjust them to your body proportions up to a certain degree. This includes the seat post, the handlebars and the stem as well as the brake levers.

As all works require know-how, experience, suitable tools and skills, you should restrict yourself to adjusting your seating position CENTURION dealer, if you are not happy with your seating position or if you want something changed.

Adjusting the saddle to the correct height

The correct saddle height depends on the length of your legs. When pedaling, the ball of your foot should be positioned above the center of the pedal axle. With your feet in this position you should not be able to stretch your legs completely straight at the lowest point,

otherwise your pedaling will become awkward

Check the height of your saddle with flat-soled shoes. This is best done with suitable cycling shoes.

Sit on the saddle and put your heel on the pedal at its lowest point. Your leg should be fully stretched and your hips should remain horizontal.

To adjust the saddle height loosen the quick-release lever (see the chapter “How to use the quick-releases“) or the binder bolt of the seat post clamp at the top of the seat tube able tools, e.g. an Allen key, with which you turn the bolt two to three turns counterclockwise. Now you can perform the vertical adjustment of the seat post.

Be sure not to pull out the seat post too far – the

mark on the seat post (end, max., min., stop or the like) should always remain within the seat tube – and always grease the part of an aluminum or titanium seat post that is inserted into a seat tube made of aluminum, titanium or steel. Do not grease carbon seat posts and/or carbon seat tubes in the clamping area! Use special carbon assembly paste instead.

Children and adolescents need to have the saddle height and the position of saddle and handlebars checked at least every three months!

Adjusting the height of the handlebars

The height of the handlebars compared to the saddle and the distance between saddle and handlebars determines how much your upper body will be inclined forward. Lowering the handlebars gives you a streamlined position and brings more weight to bear on the front wheel. However, it also entails an extremely forward leaning posture which is tiring and less comfortable, because it increases the strain on your wrists, arms, back, upper body and neck.

There are three different stem systems that allow vertical adjustment of the handlebars, i.e. the conven- tional, the adjustable and the Aheadset These systems require special knowledge.

In the event of such emergency brakings, the rider’s

weight shifts forward abruptly, thus reducing the load on the rear wheel. The rate of deceleration is primarily limited by the danger of the rear wheel losing contact with the ground, resulting in an overturning of the CENTURION bike and, secondly, by the grip of the tires on the road. This problem becomes particularly acute when riding downhill. Therefore, in case of an emergency braking you should try to shift your weight towards the rear and the ground as far as possible.

Actuate both brakes simultaneously and bear in mind that, due to the weight transfer, the front brakes can generate a far better braking effect on a surface with good grip.

Synchronizing and readjusting

Almost all brake designs have a bolt located next to one or both brake calipers for adjusting the spring preload gap changes between brake pads and rim.

Adjust the spring in a way that with an unapplied brake the gaps are equal on either side and the brake pads touch the rim simultaneously during braking.

The position of the brake lever where the brake starts to act, also referred to as the pressure point, can be adjusted to the size of the hand as well as to individual convenience by readjusting the brake cable. Make absolutely sure you cannot pull the brake lever all the way to the handlebar grip. With an unapplied brake the brake pads should not be too close to the rim sides, otherwise they could drag along the rim during riding. Before doing this adjustment, observe the notes in the chapter “Adjusting the brake lever reach”.

To readjust the brakes, unscrew the knurled lock ring located at the point where the brake cable enters the brake lever on the handlebars knurled, slotted adjusting bolt by a few turns. This reduces the free travel of the brake lever. Keeping the adjusting bolt firm, tighten the lock ring against the brake lever unit. This prevents the adjusting bolt from coming loose by itself.

Disc brakes

Functioning and wear

(g+h)

The most striking feature of disc brakes their outstanding braking effect. They respond a lot faster in wet conditions than rim brakes do and achieve their normal high braking power within a very short time. They require little maintenance and do not wear down the rims as rim brakes do. Disc brakes consist of the brake caliper, the rotor, the brake lines or cables as well as the brake lever unit. Actuating the brake lever compresses the hydraulic pistons through hydraulic pressure or mechanically, pushing the brake pads against the rotor.

The friction generated by braking causes wear to the brake pads as well as to the rotors. Frequent rides in the rain and dirt and over hilly terrain can accelerate wear on both braking surfaces. Depending on the manufacturer and the model there are different ways of checking the brake pads and rotors for their wear limits.

Wear and maintenance

To a certain extent, the wear of the brake pads can be compensated for directly at the brake lever. Unscrew the knurled lock nut on the bolt through which the cable enters the grip and then unscrew the bolt until the lever has the desired travel nut by taking care that the slit of the bolt head does not face upward or forward, as this would permit an unnecessarily high amount of water or dirt to enter.

After readjusting check the functioning and make sure the brake pads do not drag when releasing the brake lever and spinning the wheel.

Repeated readjustment at the brake lever makes the arm on the brake caliper change its position. This can make the brake less effective and result in a complete brake failure in an extreme case. Risk of an accident!

Some models offer further ways of adjusting the brakes directly at the brake caliper, though this requires a certain amount of skill. Read the instructions of the brake manufacturer on this CENTURION CD-ROM carefully before adjusting the brake. If you are in doubt or if you have any questions, contact your CENTURION dealer.

Roller, drum and back-pedal brakes

These types of brakes have an enclosed design; brake pads and surfaces inside the hub body are largely protected against the influences of the weather. The braking force is transmitted through cables from the levers to the brakes. As rear brakes they are mostly connected to an internal gear hub and sometimes they are operated by back pedaling.

With back-pedal brakes maximum braking force is

achieved by stepping on one of the pedals in its rearmost position with the cranks horizontal. With internal gear hubs from SRAM braking force is increased when having shifted to a lower gear.

The risk of overheating is particularly high with these brake systems. Brake overheating occurs on prolonged (steep) downhill rides with permanent brake dragging. Brake fading is a result thereof which, in

extreme cases, can lead to brake failure.

(g)

Therefore, if you notice that the braking effect deteriorates, stop and let the brake system cool down. Sometimes, it will be enough to operate the front and rear brake in an alternating pattern. If that will not suffice, stop for a couple of minutes before you set off again.

Brake cables which are damaged, e.g.

or less effective than usual, do not ride your bike. In such a case contact your CENTURION dealer immediately.

Keep in mind that the back-pedal brake is ineffective if the chain has jumped off. Risk of an accident!

The gears

Derailleur gears

The gears of your CENTURION bike adjust the gear ratio to the terrain you are riding on and the desired speed.

A low gear (where in the case of derailleur gears the chain runs on the small chainwheel and a large sprocket) allows you to climb steep hills with moderate pedaling force. You must, however, pedal at a faster pace. High gears (large chainwheel, small sprocket) are for riding downhill. Every turn of the pedals takes you many meters forward at correspondingly high speed.

when shifting through the chainwheels continue pedaling slowly and without force.

there is a short interruption of the drive. If you

continue pedaling, the high chain forces could result in a chain failure.

Continue pedaling at reduced cadence during gear shifting, however, at clearly reduced pedaling force. In particular

With CENTURION pedelecs reduce the cadence and the pedaling force shortly before you start shifting. In doing so

Practice shifting gears in a place free of traffic until you are familiar with the functioning of the levers or twist grips of your CENTURION bike.

CENTURION pedelecs have only one chainwheel. As a consequence there is no front derailleur and no shifter on the left handlebars.

(e)

Read the gear manufacturer’s operat-

gears until you are familiar with it before you set off for the first time.

Functioning and operation

Derailleur gears always work according to the following principle:

Large front chainwheel – high/heavy gear – higher gear ratio Small chainwheel (front) – low/easy gear – lower gear ratio Large rear sprocket – low/easy gear – lower gear ratio Small rear sprocket – high/heavy gear – higher gear ratio

Normally the shifters are mounted as follows: Shifter right – rear sprockets Shifter left – front chainwheels

Modern city/trekking bikes can have up to 33 gears. As there are, however, overlapping ranges, actually 15 to 21 gears are usable. It is not advisable to use gears which involve an extremely oblique run of the chain, as this reduces power transmission efficiency and hastens wear of the chain.

Checking and readjusting

The derailleur gears of your bike were carefully adjusted by your CENTURION dealer before delivery. However, Bowden cables may stretch a little over the first kilometers, making gear shifting imprecise and the chain rattle.

Adjusting the front and rear derailleur is a job only for an experienced mechanic.

Adjusting the rear derailleur

Increase the tension of the Bowden cable by turning the adjustable cable stop at the shifter lever or the adjusting bolt through which it runs into the rear derailleur and turn the bolts counterclockwise in half turns until the cable is slightly tensioned. After tensioning the Bowden cable check whether the chain immediately climbs onto the next larger sprocket.

The limit screws are adjusted by your CENTURION dealer. They do not alter their position during normal use.

If necessary, correct the position by means of the limit

screws. The limit screws on rear derailleurs are often marked “H” for high gear and “L” for low gear. “High gear” means that the chain is running on the smallest sprocket. Turn the screw clockwise to shift the rear derailleur towards the wheel and counterclockwise to shift it away from the wheel.

Turn the limit screw marked “L” clockwise until the rear derailleur stops moving towards the spokes and can neither be moved by actuating the shift lever nor by pushing it with your hand.

This adjustment prevents the chain from getting stuck between sprocket and spokes or the rear derailleur or the derailleur cage from touching the spokes, which could result in damage to the spokes, the rear derailleur and the frame. In the worst case, it could be impossible to continue cycling.

Adjusting the front derailleur

The range within which the front derailleur the chain on the chainwheel without itself touching the chain is quite small. If the chain tends to jump off the chainwheel, you will need to reduce the movement range in the same way as with the rear derailleur, i.e. by turning the limit screws marked “H“ and “L“. The limit screws are adjusted by your

Multi-speed hubs (internal gear hubs)

Functioning and operation

(d+e)

The advantages of multi-speed hubs enclosed design. Unlike derailleur gears the gear drive is within the hub body, only the primary ratio from the chainwheel to the sprocket being outside. What is more, all the gears can be shifted through with one gear shifter.

Provided that it is serviced regularly, the drive chain has a comparatively longer service life. And this applies even more if it is protected from the influences of the weather by a sealed chain box.

With multi-speed hubs normally the power transmission and the gear ratio adjustment is guaranteed via one or several planetary gears, depending on the number of gears. To shift gears the pedal force should be reduced shortly.

In contrast to derailleur gears, multi-speed hubs cannot only be combined with manually actuated brakes (rim, drum, roller or disc brakes), but also with back-pedal brakes

(roller or drum brakes) that are actuated by a reverse rotation of the pedals. The most effective braking is achieved with the pedals in the horizontal position.

In the case of multi-speed hubs and gearbox shift systems “1” stands for the first, lowest gear. The gears are shifted through one after the other, if possible without turning the pedals, at least, however, at reduced pedal pressure. The highest number stands for the highest gear.

With NuVinci the actual gear ratio is indicated to the cyclist on the display. If the cyclist climbs uphill, the gear ratio is low; on level ground the gear ratio is high.

The H-Sync gear system integrates the NuVinci Harmony

gear hubs into the Intuvia system of its Bosch drive. With H-Sync you can predefine your preferred cadence (between 30 and 80 turns per minute). The drive readjusts automatically – both uphill as well as downhill. This allows you to always maintain your preset cadence.

Chain – care and wear

Chain maintenance

Regular and correct lubrication of your bike’s chain makes for enjoyable riding and prolongs its service life. It is not the quantity, but the distribution and regular application of lubricant that counts. Clean the dirt and oil off your chain with a slightly oily rag from time to time they even have a damaging effect.

Having cleaned the chain as thoroughly as possible, apply chain oil, wax or grease To lubricate the chain, drip the lubricant onto the rollers of the lower run of the chain while you turn the crank. Once this is done, turn the cranks a few more times; then let your CENTURION bike rest for a few minutes so that the lubricant can disperse. Finally wipe off excess lubricant with a rag so that it does not spatter around during riding or can collect road dirt.

Make sure the braking surfaces of the rims, the rotors and the brake pads remain clear of lubricants, as the brakes will fail otherwise!

For the sake of the environment, only use biodegradable lubricants. Bear in mind that some of the lubricant can end

(f)

Although the chain is one of the wearing components of your CENTURION bike, there are still ways for you to prolong its life. Make sure the chain is lubricated regularly, especially after riding in the rain. Try to only use gears which run the chain in the straightest line between the sprockets and chainwheels and get in

the habit of high cadence pedaling.

The chains of bikes with derailleur gears are worn out

after approx. 1,000 to 3,500 km or 50 to 125 hours of use. Heavily stretched chains impair the operation of derailleur gears. Cycling with a worn-out chain also accelerates the wear of the sprockets and chainwheels. Replacing these components is relatively expensive compared with the costs of a new chain.

It is therefore advisable to check the condition of the chain at regular intervals.

Your CENTURION dealer has accurate measuring instruments ing the chain should ideally be left to an expert, as this requires special tools. In addition, you need to select a chain matching your gear system.

The wheels and the tires

The wheel consists of the hub, the spokes and the rim. The tire is mounted onto the rim so that it encases the tube in the case of the most common system, i.e. the clincher or folding tires. There is a rim tape running around the rim well sensitive tube against the edges of the rim trough, which are often sharp.

The wheels are subjected to considerable stress through the weight of the rider and any carried baggage as well as through bumpy road surfaces and terrain. Although wheels are manufactured with great care and delivered accurately trued, spokes and nipples can lose a little tension on the first kilometers. Ask your CENTURION dealer to check and true up the wheels after you have bedded them in over about 100 to 300 kilometers or 5 to 15 hours of use.

After the bedding-in period, check the wheels regularly. It will, however, rarely be necessary to tighten the spokes

Truing (retruing) wheels is a difficult job which you should definitely leave to your CENTURION dealer.

Tires, inner tubes, rim tape, inflation pressure

The tires should provide grip and traction. At the same time they should run smooth and enhance the rider’s comfort by absorbing small shocks. Both the rolling friction and the grip depend on the nature of the tire carcass, the rubber compound and the tire

tread. Your CENTURION dealer would be glad to help you choose from the numerous types of tires

(c)

If you want to mount a new tire, you need to mind the sizing system and the actual size of the old tire. The latter is specified in two different units on the side of the tire. One of the sizes is the standardized size in millimeters which is more precise, e.g. the number

sequence 40-622 width when fully inflated and has an inner tire diameter of 622 millimeters. The other size is indicated in inches (e.g. 28x1.5”).

The tires must be inflated to the proper inflation pressure to provide an optimal compromise between smooth running and riding comfort. Properly inflated tires are also more resistant to punctures. An insuf-

ficiently inflated tire can easily get pinched (“snakebite”), when it goes over a sharp curb.

The air pressure recommended by the manufacturer is given on the tire side or on the type label lower of the two pressure specifications makes for better cushioning for lightweight riders and is therefore best for cycling on a rough surface. Rolling resistance on level ground decreases with growing pressure, but so does comfort. Highly inflated tires are therefore most suitable for heavy riders and for riding on tarred roads. Therefore, adjust the pressure to your weight and your riding habits.

Inflation pressure is often given in the old system of units, i.e. in psi (pounds per square inch). The table

(f)

gives the most common pressure values in terms

of both systems.

Clincher and folding tires and rim alone are not able to hold the air. Therefore, an inner tube is placed inside the tire to maintain the air pressure and the tube is filled via a valve.

The rims of clincher and folding tires require, in general, a high-value rim tape. This rim tape protects the inner tube from the braking heat which could make the tire burst.

3. Dunlop or Woods valve

: the usual valve.

Tires with Schrader valves can conveniently be inflated at car filling stations with a compressed air dispenser. The same applies to Dunlop and Presta valves fitted with a special adapter. A compressed air dispenser must be used very carefully in short bursts as you may otherwise overinflate the tire and make it burst.

To let out air, press the needle in the center of the Schrader valve or the knurled nut of the Presta valve

(d)

All valve types come with a plastic cap to protect them from dirt.

The Schrader and Dunlop valves can be inflated with a suitable pump directly after removing the protective cap.

With Presta valves you first have to undo the small knurled nut a little and depress it carefully until air starts to escape. Check the valve core is tightened and seated in its stem, otherwise air may slowly leak out. Do not forget to tighten by hand the valve nut after inflating.

In the case of the Dunlop valve unscrew the knurled nut until air comes out of the valve. Retighten the knurled nut subsequently. Normally, you have to inflate the tire completely.

It can be hard to inflate tires to the necessary pressure by using hand pumps. It is much easier with a track pump equipped with a pressure gauge.

Rim trueness and spoke tension

For the true running of the wheel it is imperative that the tension exerted by the spokes is distributed evenly around the rim. If the tension of a single spoke

changes, e.g. as a result of riding fast over a curb or of a loose nipple, the tensile forces acting on the rim become unbalanced and the wheel will no longer run true. The functioning of your CENTURION bike may even be impaired before you notice the wobbling appearance of a wheel that has gone out of true.

With rim brakes the sides of the rims also serve as braking surfaces. An untrue wheel can impair your braking effect. It is therefore advisable to check the wheels for trueness from time to time. For this purpose lift the wheel off the ground and spin it with your hand. Watch the gap between the rim and the brake pads. If the gap varies by one millimeter or more, you should ask your CENTURION dealer to true up the wheel

Loose spokes must be tightened at once. Otherwise the load on the other spokes and the rim will increase.

Truing (retruing) wheels is a difficult job which you should definitely leave to your CENTURION dealer.

Tire puncture

Flat tires are the most common cause of puncture during cycling. However, as long as you have the necessary tools and a spare tube or a repair kit, this need not mean the end of your cycle ride. If your wheels are attached with quick-releases to the frame and the fork, you only need two tire levers and a

Dismounting wheels

If your bike has mechanical rim brakes (cantilever and V-brakes) you first have to unhook the brake

cable from the brake arm rim with one hand and press the brake pads and/ or arms together. In this position the usually barrel shaped nipple of the lateral brake cable or the brake hose (of V-brakes) can easily be disengaged.

Dismounting tires

Remove the cap and the fastening nut off the valve and deflate the tire completely sides from the rim side towards the center of the rim. This will ease the removal.

Apply a plastic tire lever to one bead of the tire about 5 cm beside the valve and lever the tire out of the rim in this area Slip the second tire lever between rim and tire at a distance of about 10 cm on the other side of the valve and lever the next portion of the bead there over the edge of the rim.

After levering a part of the tire bead over the edge of the rim you should normally be able to slip off the whole tire on one side by moving the tire lever around the whole circumference. Now you can remove the inner tube. Make sure the valve does not get caught in the rim, as this can damage the inner tube. If necessary you can remove the whole tire by pulling the other tire bead off the rim.

. Inflate the inner tube slightly so that it becomes round and push it into the tire all the way round. Make sure not to leave any folds in the inner tube.

To finish mounting the tire, start at the opposite side of the valve. Using your thumbs, press as much of the second bead of the tire over the edge of the rim as you can.

Make sure the inner tube does not get pinched and squashed between the tire and the rim. You can prevent this by pushing the inner tube into the hollow of the tire with a finger as you work along

Mounting wheels

To mount a wheel follow the reverse procedure of wheel dismounting. Make sure the wheel is correctly seated in the drop-outs and accurately centered between the fork legs or the rear and chainstays. Make sure that the quick-release and the drop-out catches are correctly seated tion see the chapter “How to use quick-releases and thru axles”.

If you have V-brakes hook up the brake cable at the brake arm. To do this, grip the rim with one hand and press the brake pads and/or the brake arms together. In this position the aluminum bow can easily be engaged.

If you have disc brakes, check before mounting the wheel whether the brake pads rest snugly in their seats in the brake caliper body. The gaps between the brake pads and the wheel should be parallel and the wear indicators in their correct position. Make sure that you push the brake disk between the brake pads. After mounting the wheel and tightening the quick-release, pull the brake lever (several times, if you have disc brakes).

If your bike has a multi-speed hub, back-pedal, drum or roller brakes, verify the proper assembly of the individual components and tension the chain before tightening the wheel nuts by pulling the wheel backwards.

The headset

The headset allows it to move freely. It must afford virtually no resistance to moving, if your CENTURION bike is to go straight, stabilizing itself as it runs. The shocks caused by uneven road surfaces expose the headset to considerable levels of stress. In this way it can become loose and maladjusted.

Checking and readjusting

Check the headset for play by placing your fingers around the upper head tube race weight to bear on the saddle, pull the front brakes with your other hand and push the CENTURION bike firmly back and forth with the wheel remaining on the ground. If the bearing has play, you will feel the upper head tube race moving in jerks relative to the lower head tube race - visible as a small gap in between the head tube races

To check the bearing for ease of running, lift the frame until the front wheel is suspended in the air The handlebars should turn from far left to far right without feeling roughness or tightness at any point. With a gentle tap on the handlebars the fork should turn easily from the middle position.

Threadless headsets – Aheadset®

This headset system is characterized by the fact that the stem is not in the fork steerer tube but clamps

it from outside. Hence the stem is an important constituent part of the headset, clamping it therefore also sets the adjustment. You generally only need one or two Allen keys and a torque wrench to adjust an Aheadset

Release the clamping bolt(s) located on the side of the stem by one to two turns. Gently tighten the countersunk adjusting bolt on top a little, e.g. by a quarter turn, by using an Allen key.

Align the stem so that the handlebars are not slanted. Make sure the front wheel is in line with the top tube and the stem. Tighten up the stem clamping screws. Use a torque wrench and never exceed the maximum torque values! You will find the prescribed values in the chapter “Recommended torque settings”, directly on the components and/or in the operating instructions of the component manufacturers on this

Suspension

Glossary

Suspension fork

Bicycle fork absorbing and damping shocks through moving components. The most common among these forks are the telescopic suspension forks. What is designated as stanchion tubes are the thinner tubes press fitted or screwed to the fork crown of a telescopic fork. What is designated as lower leg are the lower tubes in which the stanchion tubes slide in.

Rear shock

The rear shock is the element combining the spring as well as the damping in the rear frame of a full suspension bike. Often the rear shock is also designated as shock absorber.

Spring rate or hardness

The force that is required to compress the spring by a certain suspension travel – measured in Newton per millimeter (N/mm) or pound per inch (lbs/in). A higher spring rate requires more force for the travel. In pneumatic spring elements this corresponds to a higher pressure.

(a+b)

Spring preload

In the case of the widespread air suspension systems, the air pressure in the fork is crucial for the spring rate and the spring preload. Observe the recommendations of the manufacturers. Within a certain range a preload can be applied to the coil springs. Then the suspension only reacts when a greater load is applied. However, the spring rates are not changed

as a result. Heavy riders cannot compensate a too low spring rate with a higher preload.

Negative suspension travel (“sag”)

The suspension travel that is taken up by the rear structure or the fork when the rider takes up his or her usual riding position at a standstill. This is usually specified as a percentage of the overall suspension travel.

Rebound damping

In most cases a red adjusting knob. Delays or brakes the rebound. Prevents bike bobbing.

Lockout

In most cases a lever on the suspension element or the handlebars.

A device to block the fork or the rear shock so that the suspension element does not cause bob when riding on tarred roads or smooth surfaces. Not to be used off road.

(d)

(c)

Platform damping

Increases the (low speed) compression damping rate and suppresses bobbing. As opposed to the lockout function, the suspension is not blocked completely.

Suspension forks

Adjusting the spring rate

Most city/trekking bikes and pedelecs are equipped with suspension forks better control of your bike when riding cross-country or on rough road surfaces and ensures more ground contact for the tire. It noticeably reduces the strain on you and your bike caused by the mechanical shocks from the terrain.

Suspension forks differ in their types of spring elements and damping. Suspension forks normally work with air spring elements or less often with coil springs. Damping is usually done by oil.

To work perfectly, the suspension fork has to be adjusted to the weight of the rider, the sitting posture and the intended use. Be sure to have this adjustment carried out by your CENTURION dealer at the time of delivery.

Note in general that the suspension fork must give in a little even when you are just sitting on the bike – this is the so-called negative suspension travel or sag. If you ride over a pothole the spring is decompressed and the suspension fork compensates for the unevenness. If the air pressure or the spring preload is too high, this effect is lost because the suspension fork is already fully extended. This means that an important comfort and safety factor is lost if the tire

briefly loses contact with the ground.

The suspension fork should yield by 10-20 % of the maximum suspension travel.

To measure the travel you can use the rubber ring

(g)

mainly located on the thinner, plunging tube of the suspension fork. If there is no rubber ring, tie up a cable tie around one of the stanchion tubes

Make sure it is not too tight, you should still be able to move it, it should however not slip by itself.

(h)

Put on your usual riding clothing (including if necessary a packed rucksack), sit on your bike and bring yourself into the usual riding position. Lean against a fixed object (railings, wall etc.) and make sure you do not fall over. Ask a helper to move the rubber ring or the cable tie downwards against the dust seal at the lower leg.

Get off your bike so that the fork does not compress any more. The distance between the rubber ring/ cable tie and the wiper is the negative suspension travel, or sag

. Compare it against the total suspension travel (as specified by the manufacturer) to determine whether the suspension should be set to be harder or softer.

In the case of most suspension forks with coil springs a preload can be applied to the springs within tight limits by turning a knob at the top of the fork crown. If that is not possible and the desired negative suspension travel (“sag”) cannot be set, the coil springs must be replaced by harder or softer models. The replacement is a job for the CENTURION dealer.

When replacing any parts, be sure to only use parts that bear the appropriate mark and, to be on the safe side, original spare parts. Your CENTURION dealer will be pleased to help you.

With pneumatic suspension forks the spring rate is set by the air pressure in the fork. The pressure must be set before the first ride by means of a special high-pressure pump with pressure gauge

(c)

Note the appropriate setting values and check them subsequently at regular intervals. Always follow the recommendations of the manufacturer and never exceed the maximum air pressure for the suspension fork. Always make a test ride after each change to the settings.

Check afterwards the position of the rubber ring/

cable tie. Its distance from the wiper is the maximum suspension travel that you have used. If the rubber ring/cable tie has moved by even a few millimeters, the setting of the forks is too hard. Reduce the pressure, or, in the case of coil springs, the spring preload. If that brings no improvement, have the springs replaced.

If the rubber ring/cable tie has shifted over the entire

length of the tube or if the fork audibly bottoms out and hits the top repeatedly when riding off-road or on bad roads, the setting of the springs is too soft. In the case of air-suspension forks the pressure must be increased. In the case of steel coils, have them replaced by your CENTURION dealer.

This noise is caused by the sudden complete compression of the suspension fork as it reaches bottom out. If the suspension fork frequently reaches bottom out, it will fail over time, and so will the frame.

Adjusting the damping

The damping is adjusted by valves inside. When the oil is forced through these valves this slows down the speed with which the suspension fork is extended or compressed and prevents the suspension “bouncing” after hitting an obstacle. This is how the reaction to obstacles can be optimized.

Suspension forks with adjustable rebound damping have an adjusting knob (mostly red) to slow down or accelerate the rebound movement. If a second (mostly blue) knob is available, the compression speed can be set and/or the lockout function can be activated.

Start the setting with a completely open damping

(rebound and compression on “-“). Take hold of the handlebars with both hands and pull the front brake. Lean with your entire weight on the fork and remove your weight immediately. The fork will extract at the same speed as you made it compress.

Turn the red adjusting knob in the direction “+“ until you hear a click. Compress the fork once again with the front wheel brake pulled and the remove the weight abruptly once again. You will note that the fork extends more slowly.

Repeat the compression and the release by continuously turning the rebound damping. You will get a feeling for the working of the rebound damping.

The typical setting of the rebound damping is an extension of the suspension components at reduced speed, however not at a sluggish pace. A rebound movement at reduced speed ending up in a sluggish movement is a definitely too high damping.

Ride over an obstacle (e.g. down a curb) subsequently and turn the rebound damping in small steps towards the “+” setting. You have found the proper rebound setting when the suspension fork does not cycle more than once. Always check a changed adjustment during a test ride in the terrain

If you do not feel comfortable adjusting the damping or if you face any problems with the adjustment, contact your CENTURION dealer or follow the corresponding operating instructions of the suspension fork manufacturer, which you can find enclosed on this CENTURION CD-ROM.

Maintenance

Suspension forks are components of sophisticated design that require regular maintenance and care. This has led almost all suspension fork manufacturers to establish service centers where you can have your forks thoroughly checked and overhauled at regular intervals according to use, e.g. once a year.

The following routines are essential for maintenance:

1. Make sure the sliding surfaces of the stanchion

2. Clean the suspension fork, if it is soiled, directly

3. After washing your bike, spray the stanchion tubes of the suspension fork with a little lithium-free grease spray of hydraulic oil. Compress the fork several times and wipe off excess lubricant with a clean rag before you set off for your next ride.

4. Do not use a steam jet/high-pressure cleaner or

aggressive cleaning agents for cleaning! Ask your CENTURION dealer for an appropriate cleaning agent.

5. If your suspension fork has steel coils, you should regularly have the coils cleaned and lubricated with non-corrosive resin-free grease. Some fork manufacturers supply special greases for fork maintenance. Strictly observe the recommendations of the manufacturers. These are routines for the suspension fork service center.

6. Suspension forks with pneumatic springs must be checked regularly for air pressure, since the air escapes over time.

Suspension elements are of sophisticated design. The maintenance routines and above all the disassembly of the suspension elements are jobs best left to your CENTURION dealer or the fork manufacturer’s service center.

Suspension forks are constantly being sprayed with water and dirt from the front wheel. Clean them with plenty of water after every ride.

Riding a CENTURION pedelec – Special features

Your CENTURION pedelec is designed to be used like a conventional bicycle. The unique riding experience, however, starts when you actuate the drive system ated by the 250 W motor torque the stronger you pedal.

Set off for your first ride by selecting the lowest level of drive assistance. Gradually get used to the additional power. Slowly approach the potential of your CENTURION pedelec in an area free of traffic.

Practice typical riding situations such as starting off and braking, tight corners and riding on narrow cycle paths and lanes. This is where a CENTURION pedelec clearly differs from a conventional CENTURION bike.

Riding with drive assistance

The system is switched on and off at the buttons of the control element on the battery or on the handlebars. Furthermore, different assistance modes can be selected, the remaining capacity of the rechargeable battery is displayed and the different functions of the cycle computer

When switched on, the system activates during pedaling and the drive assistance is available. Sensors measure your pedaling movements and control the fully automated drive assistance according to the selected assistance mode. The level of the additional propulsion depends on the assistance mode, your speed and, as applicable, the amount of force applied to the pedals.

The assistance switches off when you reach a speed of more than 25 kmh.

Keep in mind that you may have to change your riding habits: Do not mount by placing one foot on the pedal and by trying to throw the other leg over the saddle. The CENTURION pedelec would set off suddenly. Risk of an accident!

Stop pedaling earlier than you are used to before riding a turn or bend. Otherwise there may be too much propulsion and your cornering speed may be too high.

Do not give in to the temptation to always ride in a high gear, due to the strong motor. Change gears frequently CENTURION bike to make your own contribution to moving forward as efficient as possible. Your cadence should always be in a smooth flow. In other words, you should pedal at more than 60 crank rotations per minute.

Keep in mind that the other road users are not yet used to the new pedelecs and their higher speeds. Ride with this fact in mind and anticipate the actions of other road users. Be aware that the speed you ride at will be clearly faster than you are used to. Therefore, keep these facts in mind and be ready to brake whenever unclear or possibly dangerous situations come into your field of vision.

Range – Useful information for a long ride

How long and how far you can benefit from the auxiliary drive depends on several factors, i.e. the road conditions, the weight of the rider and any additional load, the rider’s pedal force, the degree or mode of assistance, (head)winds, frequent stops, temperature, weather conditions, topography, tire pressure, etc.

Useful information for proper handling of the rechargeable battery

Remove the rechargeable battery do not use your CENTURION pedelec for a longer period of time (e.g. during the winter season). Store the rechargeable battery in a dry room at temperatures between 5 and 20° Celsius. The state of charge should be 50 to 70 % of the charging capacity. Check the state of charge, if the rechargeable battery is left unused for more than two months, and recharge it in between, if necessary

Clean the battery housing with a dry or, if at all, a slightly moist rag. Do not direct the water jet of a high-pressure cleaner at the rechargeable battery, as there is a risk of water entry and/or short-circuit.

CENTURION kids’ bikes

Useful information for parents

Children are among the most vulnerable road user groups, not only because of their lack of experience and practice, but also for the simple reason that

they are smaller and may therefore have difficulties overseeing things and be easily overlooked by other road users.

If you want your child to use his/her CENTURION bike on the road, you should be willing to invest time in road safety instruction and help him/her improve his/her riding skills You should therefore check the CENTURION kids’

bike regularly and, if necessary, re-adjust and service it. If you are in doubt or if you have any questions, contact your CENTURION dealer.

Bear in mind that it is your responsibility to supervise your child on his/her first rides and do not overchallenge your child! Inform yourself about the traffic rules in your country. They vary from country to country.

It is essential that your child has good control of his/

her CENTURION bike roads. As a first step in this direction we recommend that you give your child a scooter or a pedalless bike so that he/she can train his/her sense of balance.

(b+c)

. Children are less attentive.

(d)

before riding on public

This being accomplished you will need to make your child familiar with the functioning of the brakes and gears before you let him/her sit on his/her CENTURION bike. Find a place away from the road, ideally a backyard or park, where you can practice braking and shifting gears with your child under your supervision.

Once your child has progressed to a point where he/ she can ride in traffic cross curbs and railway tracks, i.e. to cross these obstacles, if possible, at right angle. Your child should also learn to look ahead and back for any danger before taking this kind of obstacle.

Set a good example when it comes to wearing a cycling helmet and to riding on cycle lanes. It is also advisable to let your child take part in road safety lessons offered at schools or by local clubs and associations.

(b)

Encourage your child to tell you at once if anything should not be working properly on his/her CENTURION bike or if there are any noises. Rectify the fault immediately or take the bike to your CENTURION dealer for repair.

Children and adolescents need to have

the saddle height and the position of saddle and handlebars checked at least every three months!

Handlebars that are too far away from the saddle or adjusted in a too high/low position can also lead to the fact that the child is less confident and relaxed during cycling. Normally, kids’ bikes allow adjustments of the saddle tilt and sometimes the tilt of the handlebars can be adjusted as well.

Special attention should be paid to the adjustment of the control elements, such as brake levers. Easy reach and operation should be ensured for the child.

For more information on how to perform the adjustments of the CENTURION kids’ bike to the proportions and needs of your child, read the chapter “Adjusting the CENTURION bike to the rider”. If you are in doubt or if you have any questions, contact your CENTURION dealer.

Get into the habit of doing the checks as described in the chapter “Before every ride” together with your child. In this way, your child will learn to handle the CENTURION bike properly and you will be able to detect any defects that have developed during use.

Lighting system

When riding on public roads a properly functioning lighting set is obligatory (see the chapter “Legal Requirements for Riding on Public Roads”).

Front lamp

Illuminants are either bulbs, halogen lamps or one or several LEDs, i.e. light emitting diodes, beaming white light by means of a reflector and/or a diffusion disc on the road lane.

You should be familiar with the assembly of the lighting set so that you can repair possible failures yourself.

Rear light

Either bulbs or LEDs beam through a (red) diffusion disc rearwards and are visible at best even from the side. Nowadays most rear lights provide a stand light function that is powered by a capacitor or a battery when the CENTURION bike has to stop at traffic lights, for example.

Things worth knowing about your CENTURION bike

Cycling helmets and glasses

Cycling helmets Your CENTURION dealer has a variety of styles and

sizes.

Verify that the helmet complies with the test standard DIN EN 1078. Cycling helmets are only approved for use during cycling. Observe the manufacturer’s instructions.

In addition to a cycling helmet and suitable clothing, cycling glasses are absolutely essential when you are riding your CENTURION bike. They do not only protect your eyes from the sun and the wind, but also keep out flies and other impurities that may impede your vision when they fly into your eyes. Risk of an accident!

Good cycling glasses must fit closely against your face so that the wind does not get into your eyes from the side. There are a great many different models, for example, without tinting and UV protection, which can be worn at night or in twilight conditions, or glasses with a high level of UV protection that you should wear if the sun is stronger.

Your CENTURION dealer has a wide range of cycling glasses available and will be pleased to advise you.

(c)

are absolutely recommendable.

Never ride without a helmet and glasses

(d)

! But remember that even the safest helmet is useless unless it fits properly and is correctly adjusted and fastened.

Clothing

The pedals and the shoes

Cycling trousers comfortably. These close-fitting trousers have special padding in the seat. They have no seams that can press into you and they do not form folds. Cycling trousers are therefore designed to be worn next to the skin. Another form of cycling trousers are baggy pants with inner pants including seat pad.

Since sporty cycling will soon bring you out in a sweat, a jersey made of synthetic materials is ideal fibers themselves do not take up any moisture but instead wick the sweat away from the skin up to the surface of the materials and thus prevent you getting cold from the cool wind produced by your speed. On longer tours you should in addition have suitable protection against the rain. Your CENTURION dealer would be glad to help you choose the right equipment.

Cycling shoes to provide firm support for your feet. In addition, they should have a stiff sole so that the pedal cannot press through. The sole should not be too wide in the area of the heels, as the rear stays or the crank will otherwise get in the way of your pedaling. This will

prevent your feet from assuming a natural position when pedaling and may cause knee pain in the long run.

Special cycling shoes are obligatory if your CENTURION bike is equipped with clipless pedals. With these shoes cleats are fixed to the sole. They give you a firm connection between shoe and pedal and allow depending on the model an acceptable

walking position.

The main advantage is that these step-in pedals prevent your feet from slipping off when pedaling fast. They enable you not only to push but also to pull the pedals. This makes it easier to pedal fluidly and considerably improves the transmission of the force as opposed to pedals with an open pedal cage.

The usual way to engage with the pedal is to turn it from the lowest position of the crank to the horizontal using the tip of the cleat and push down on the back of it. Normally, the shoe engages with the pedal with a click which you will hear and feel clearly.

You will be better prepared in case of a puncture.

Cycle computers

Electronic tachometers determine the travelling and average speed, the number of kilometers per day and year, and also the travelling time models show the highest speed that was reached, the difference in height, the cadence or (with a special chest strap) your pulse rate as well.

Today, there are global positioning systems (GPS) and specific power meters for optimal training on the market which are compatible with your CENTURION bike.

Fenders/wheel protections

Transporting baggage

If you want to mount fenders on your CENTURION bike, ask your CENTURION dealer for advice. There are removable mudguards clip-on mudguards, as well as firmly attached models that provide more protection.

Retrofittable fenders for a fix fastening are usually made of plastics and are secured in the correct position by means of additional stays. The length of the stay is perfect when the bottom edge of the fender runs at an approx. distance of 15 mm in parallel to the tire, i.e. concentrically, equidistantly.

For safety reasons the front wheel stays must have security fastenings. They prevent the tire from being blocked by impurities taken up by the front wheel from the ground. In this case the security fastening frees the stay and hereby prevents a possible accident. The plug connection can easily be refastened.

Damaged fenders should be replaced in

any case. Risk of an accident!

There are various ways of carrying baggage on your CENTURION bike. Your choice will primarily depend on the weight and volume of the baggage and on the bike you want to use. Using a rucksack convenient way of transporting baggage on a bike. However, your CENTURION bike is fitted with a pan-

nier rack to take heavy and bulky items with you.

It is advisable to carry baggage in stable pannier bags with a very low center of gravity.

Another possibility of transporting baggage are handlebar bags for quick mounting and removal. Handlebar bags

are particularly suitable for valuables, photographic equipment and maps that should be within easy reach.

When buying bags, make sure they are watertight so that your belongings are protected and you will not have any unpleasant surprises after the first rain shower.

Transporting the CENTURION bike or pedelec

By car

Nearly every car accessory dealer and car company offers carrier systems bike without disassembly.

The usual design involves rails fixed to the roof of the car onto which the bikes are fixed with clamps gripping the down tubes. This can, however, result in irreparable damage to the frame. High-end, very thin-walled aluminum or carbon fiber frames are particularly susceptible to this kind of damage. Due to the material properties of carbon fiber, you may not see severe damage at first sight, but it can result in an unforeseeable severe accident at a later date. There are, however, special suitable models available in the car accessory trade.

Rear carriers are becoming more and more popular. Their big advantage over roof carriers is that you do not have to lift up the bike so high to attach it. Make sure the clamps used do not cause any damage to the fork or frame. Risk of breakage!

Whatever system you opt for, make sure it complies with the relevant safety standards of your country, such as the GS mark!

, and therefore has an influence on

Your CENTURION dealer will have assembled and adjusted your CENTURION bike ready for use when you come to collect it. Nevertheless, your CENTURION bike needs regular servicing CENTURION dealer do the scheduled maintenance work. This is the only way to ensure that all components function safely and reliably for many miles.

The bike will be due for its first service after 100 to 300 kilometers, 5 to 15 hours of initial use or four to six weeks. The bedding-in phase typically involves spokes slightly losing tension or gears coming out of adjustment, so there is every reason to have your CENTURION dealer service the CENTURION bike at this stage. This bedding-in process is unavoidable. Therefore, remember to make an appointment with your CENTURION bike dealer to have your new CENTURION bike inspected. This first service is very important for both functioning and durability of your CENTURION bike.

It is advisable to have your CENTURION bike serviced regularly by your CENTURION dealer after the bedding-in phase. If you ride a great deal on poor road surfaces or cross-country, it will require correspondingly shorter service periods. The off-season during the winter months is a very good time to take your CENTURION bike to your CENTURION dealer for the annual inspection, as they will have plenty of time for you and for servicing.

Cleaning and caring for your CENTURION bike or pedelec

Dried sweat, dirt and salt from riding during the winter or in sea air can harm your CENTURION bike. You should therefore make it a habit of cleaning all components at regular intervals.

Avoid cleaning your bike with a high-pressure cleaner. The high-pressure jet is likely to enter bearings by passing through the seals and dilute the lubricants hereby increasing the friction. This destroys and impairs the functioning of the bearing races in the long term. High-pressure jets are also likely to remove frame stickers or decorations to the rims. The electronics could be damaged in the case of pedelecs

A much more gentle way of cleaning your bike is with a low-pressure water jet or a bucket of water and a sponge or a large brush. Cleaning your bike by hand has another positive side-effect: you may discover defects in the paint as well as worn or defective components at an early stage.

Check the chain for wear and relubricate after cleaning and drying wear” and the instructions of the component manufacturers on this CENTURION CD-ROM).

Wipe dry the sliding surfaces of the suspension fork and apply special spray. Apply a coat of standard hard wax on painted, metal and carbon surfaces (except from brake surfaces and brake discs). Polish the waxed surfaces after drying to give them a nice shine.

Safekeeping and storing your CENTURION bike

If you regularly look after your CENTURION bike during the season, you will not need to take any special measures when storing it for a short time, apart from securing it against theft. Store your bike in a dry, well aerated place.

If you want to store your CENTURION bike for a longer period of time, e.g. over the winter months, please observe the following things: Inflated inner tubes tend to gradually lose air when the bike is not used for a long time. If your CENTURION bike is left standing on flat tires for an extended period, this can cause damage to the structure of the tires. It is therefore better to hang the wheels or the entire CENTURION bike or to check the tire pressure regularly
