Any use other than that intended can cause accidents resulting in death or serious injury.

THM-Clavicula crank systems have been exclusively designed

- for installation on standard racing cycles, time trial and mountain bikes.

- for the permitted area of application – see Application area, page 11.

Fundamental safety precautions

The following warnings for the THM-Clavicula component apply to all Clavicula models (Clavicula Road, Clavicula MTB etc.), unless otherwise specified.

For the time being we limit the service life of your THM-Clavicula crank system to 100,000 km or 10 years. It is imperative you contact us before continuing to use your THM-Clavicula crank system after one of these limits has expired!

Always remember that riding a bicycle involves potential danger for the rider and other road users, as well as for the bicycle and its components. Even if protective equipment and safety devices are used, accidents resulting in death or serious injury can still occur.

You should also rely on your common sense and avoid any unreasonable behaviour!

Assembly & maintenance

Risk of accident caused by assembly and maintenance work which has not been conducted in a professional manner.

-Do not overestimate your technical ability. All assembly and maintenance work should be performed by a specialist workshop for bicycles. This is the only way to ensure that work is conducted in a professional manner.

-Always observe all of the specified tightening torques for the screw connections.

-Only use suitable, undamaged, high-quality tools.

-Only ever use original THM components which are available from your specialist dealer or directly from THM.

-Never make any modifications to your THM components.

-Check your crank system (incl. cranks, bottom bracket, chainwheels) to make sure it is undamaged and functioning properly before every ride. Send us your THM-Clavicula component before further use if damage is visible (cracks, fractures, deformations, etc.) or if you are in any doubt about its functionality.

-Check your THM components before each journey to ensure the surfaces are completely undamaged. Send us your THM components for inspection before further use if damage is visible (deep scratches in the paintwork which extend into the carbon structure, large abrasions, etc.), if you are in any doubt about their functionality or if the Clavicula lettering is abraded at one or more points (wear indicator).

-Always ensure your bicycle is maintained in a flawless condition. Care and maintenance will prolong the service life of your bicycle and its components and also improve your personal safety.

 Apply grease to the threads of the pedals.  Assemble your pedals.

Finishing touches

Risk of accident caused by a malfunctioning crank system due to loose screw connections.

-Check the required tightening torque of all screw connections after the first 100 km – re-tighten the connections if necessary. Repeat this check every 2500 km!

Risk of accident caused by a malfunctioning crank due to wear.

-Do not continue to use your Clavicula component if the Clavicula lettering is abraded at one or more points (wear indicator).

Please note that if you use overshoes, or if there is an extremely small clearance between the brake shoe and crank, it will cause the crank surface to wear. This level of wear is increased significantly if the bike is used frequently in wet and dirty conditions! You can counteract this wear by sticking an appropriate protective film (Lizard Skins or other similar film) over the areas that are susceptible to wear. Check these areas for wear at regular intervals!

 Check the position and adjustment of the front

derailleur as well as the chain line. Readjust the front derailleur if required.

Maintenance

WARNING

NOTICE

Important maintenance information

If not properly performed, assembly and maintenance work could cause accidents resulting in death or serious injury.

-Do not overestimate your technical ability. All assembly and maintenance work should be performed by a specialist workshop for bicycles. This is the only way to ensure the work is conducted in a professional manner.

Improperly performed assembly and maintenance work could also result in a loss of your warranty rights (liability for defects)!

Risk of accident caused by damaged components.

-Never attempt to disassemble your THM-Clavicula component - only THM employees are authorised to do this.

-Always read and observe all of the assembly and maintenance instructions in this manual, as well as those provided in the manuals of other manufacturers whose products are used on your bicycle (e.g. frame, chainwheels, pedals, etc.).

-Always observe the minimum and maximum values specified – see Specifications, from page 8.

-Only use suitable, undamaged, high-quality tools.

-When conducting assembly steps that require a specific tightening torque, always use an appropriate torque wrench that is designed for the tightening torque specified.

Never use a high-pressure cleaner or steam cleaner to clean your bicycle, as the seals of your bicycle components are not able to withstand the pressure. If such cleaners are used, it would result in corrosion and material damage.

Never use caustic solvents (such as paint thinners, acetone, nitro compounds, etc.) as they can attack the surface of your THM components. Only use commercially available paint care products and water to clean your THM components. Spirit or petrol should be used carefully

- when using such products avoid excessive wiping and prolonged exposure times.

-Your THM bottom bracket is elaborately sealed and provided with permanent lubrication. There is no need to re-lubricate the bearings!

 Grasp both cranks of your bicycle.  Try to move the cranks to the left and right.

 If you feel bearing play, it means that the bottom

bracket is loose and needs to be adjusted immediately – see Adjusting the bottom bracket, page 20.

 Now shift the chain onto the smallest chainwheel.  Remove the chain from the chain ring and place it

onto the bottom bracket housing.

 The bottom bracket can now be rotated freely.

 Use two fingers to grasp one of the cranks directly

by the bottom bracket axle and rotate the axle in its bearing.

 If the bottom bracket axle rotates with perceptible

resistance, it means that the bottom bracket is too tight and must be adjusted immediately –

see Adjusting the bottom bracket, page 20.

WARNING

NOTICE

The maintenance intervals required for your bicycle depend on how often and in which weather conditions it is used. The following maintenance measures should be conducted more frequently if the bicycle is used in extreme conditions (rain, dirt, long distances, etc.). When conducting regular maintenance procedures make sure your bicycle is always clean and well protected by lubricants and cleaning agents. Ask your specialist dealer about appropriate lubricants and cleaning agents as well as information relating to their correct application.

Risk of accident caused by a malfunctioning crank system due to loose screw connections.

-Check the required tightening torque of all screw connections after the first 100 km - retighten the connections if necessary. Repeat this check every 2500km!

Risk of accident caused by a malfunctioning crank due to wear.

-Do not continue to use your Clavicula component if the Clavicula lettering is abraded at one or more points (wear indicator).

Risk of accident caused by malfunctioning brakes.

-After conducting any cleaning, maintenance or repair work make sure that the braking rims of your wheels are free from lubricants (such as grease, oil, silicon, Teflon, wax or other similar agents).

Never use a high-pressure cleaner or steam cleaner to clean your bicycle, as the seals of your bicycle components are unable to withstand the pressure. This will result in corrosion and material damage.

If you are using a hose, handle it with care - never aim the hose directly at the bearing components (fig. 1).

 Clean your THM-components at regular intervals by

using water and a non-abrasive, environmentallyfriendly cleaning agent.

 When cleaning your THM components always

check for signs of damage (dents, cracks, scratches, large abrasions, worn areas, etc.).

 Periodically preserve the surface of your THM com-

ponents using a high quality protecting wax or other similar agent.
