TO ENSURE SAFETY

TO ENSURE SAFETY

WARNING

•

When installing components, be sure to follow the instructions that are given in the instruction manuals.

It is recommended that you use only genuine Shimano parts. If parts such as bolts and nuts become loose or damaged, the bicycle may
suddenly fall over, which may cause serious injury.
In addition, if adjustments are not carried out correctly, problems may occur, and the bicycle may suddenly fall over, which may cause serious
injury.

•

Be sure to wear safety glasses or goggles to protect your eyes while performing maintenance tasks such as replacing parts.

•

After reading the dealer's manual thoroughly, keep it in a safe place for later reference.

Be sure to also inform users of the following:

•

Each bicycle's brake system may handle slightly differently depending on the model. Therefore, be sure to learn the proper braking technique
(including brake lever pressure and bicycle control characteristics) and operation of your bicycle.
Improper use of your bicycle’s brake system may result in loss of control or an accident, which could also lead to severe injury. For proper
operation, consult your professional bicycle dealer or the bicycle's owner's manual. It is also important to practice riding and your braking
technique, etc.

•

You need to use the Shimano front INTER M brake body and the hub as a set (excluding BR-C6060). The hub of the Shimano front INTER M
brake has a built-in power modulator. This system controls the braking force so that excessive force is not applied if the braking force reaches
the specified value. If the front brake is applied too strongly in case the hub is not equipped with the power modulator, the wheel may lock
and the bicycle may fall forward, and serious injury may result.

•

Never tighten the inner cable fixing bolt with it attached to your bicycle. Doing so may cause the inner cable fixing bolt to detach.

< Front >

< Rear >

•

If using the hub roller brakes in combination with a suspension fork, care must be taken when selecting the suspension fork to use. Please
consult with the shop or the bicycle manufacturer. If an incorrect type of suspension fork is selected, it could prevent the suspension fork from
functioning properly because of overheating during braking or lack of strength in the fork, which could result in an accident.

5

TO ENSURE SAFETY

•

The brake levers are equipped with a mode switching mechanism to make them compatible with cantilever brakes and roller brakes or
V-BRAKE brakes with power modulator. (BL-C6010 / BL-IM60-A is compatible with roller brakes or V-BRAKE brakes with power modulator.
Please note that it is not compatible with cantilever brakes.)

If the incorrect mode is selected it may cause either excessive or insufficient braking force to occur, which could result in dangerous accidents.
Be sure to select the mode in accordance with the instructions given in the table below.

•

When installing components, be sure to follow the instructions that are given in the instruction manuals. It is recommended that you use only
genuine Shimano parts. If parts such as bolts and nuts become loose or damaged, the bicycle may suddenly fall over, which may cause serious
injury.

•

Always make sure that the front and rear brakes are working correctly before you ride the bicycle.

•

If the road surface is wet, the tires will skid more easily. If the tires skid, you may fall off the bicycle. To avoid this, reduce your speed and apply
the brakes early and gently.

•

Check that the wheels are fastened securely before riding the bicycle. If the wheels are loose in any way, they may come off the bicycle and
cause serious injury.

•

After reading the dealer's manual thoroughly, keep it in a safe place for later reference.

For Installation to the Bicycle, and Maintenance:

•

When securing the brake arm to the frame, be sure to use a brake arm clip that matches the size of the chainstay, and securely tighten them
with the clip screw and clip nut to the specified tightening torque.
Use a lock nut with a nylon insert (self-locking nut) for the clip nut. It is recommended that standard Shimano parts be used for the clip screw,
clip nut and brake arm clip.
If the clip nut comes off the brake arm, or if the clip screw or brake arm clip becomes damaged, the brake arm may rotate on the chainstay and
cause the handlebars to jerk suddenly, or the bicycle wheel may lock and the bicycle may fall over, causing serious injury.

•

Depending on the product, the tire diameter of the compatible wheel may differ. Be sure to check the compatible size.
If an incompatible size is used, the wheels may lock and you may lose balance and fall off the bicycle.

6

TO ENSURE SAFETY

•

If the total weight of the bicycle (bicycle + rider + luggage) is indicated on the product, the power modulator that controls an excessive
braking effect is built in.
Use the compatible brake lever together. If the total weight of the bicycle is heavier than the recommended range, braking may be
insufficient; if lighter, braking will be too effective and the wheel may be locked, which may cause you to fall off the bicycle.
The power modulator is not an anti-locking device of the wheel.

CAUTION

Be sure to also inform users of the following:

•

If any of the following occur while using the brakes, stop riding immediately and ask the place of purchase to carry out inspection and repairs.

1) If an abnormal noise is heard when the brakes are applied

2) If the braking force is abnormally strong

3) If the braking force is abnormally weak
If 1) and 2) occur, the cause might be a lack of brake grease, so ask the place of purchase to grease the mechanism with special roller brake
grease.
If 2) or 3) occurs when using BR-C6060-F, the power modulator may be malfunctioning. Have it inspected/repaired at the place of purchase.

•

If the brake is used frequently, the area around the brake may become hot. Do not
touch the area around the brake for at least 30 minutes after you finish riding the
bicycle.

Area around the brake

•

Avoid continuous application of the brakes when riding down long slopes, as this will cause the internal brake parts of the Shimano INTER M
brake system to become very hot, and this may weaken braking performance. It may also cause a reduction in the amount of brake grease
inside the brake, and this can lead to problems such as abnormally sudden braking. The design of the Shimano INTER M brake system has been
carried out based on standards such as ISO (4210) and DIN (79100-2). These standards specify the performance for an overall weight of 100 kg.
However, BR-C6000-F/C6060-F is designed with the overall weight assumed to be 130 kg. If the overall weight exceeds 100 kg (130 kg for
BR-C6000-F/C6060-F), the braking force provided by the system may be insufficient for correct braking, and durability of the system may also be
reduced.

•

The front INTER M brake system should only be installed to the left side of a bicycle which is 26 inch” or larger.
If it is used on a bicycle which is smaller than 26 inch”, the braking force may be too great, which could cause accidents.

•

In order to get the best performance from the Shimano front INTER M brake, be sure to use Shimano brake cables and brake levers as a set.
(http://productinfo.shimano.com/lineupchart.html) (The amount of movement of the inner cable must be: 21.5 mm (when using BL-C6010) /

16.5 mm (when using BL-C6000 / BL-IM60 / BL-IM65 / BL-IM45) or more when the brake lever is pressed. If it is less than 21.5 mm / 16.5 mm,
braking performance will suffer, and the brakes may fail to work.)

•

If the brake cable becomes rusted, braking performance will suffer. If this happens, replace the brake cable with a genuine Shimano brake
cable and re-check the braking performance.

•

The brake unit and front hub unit should never be disassembled. If they are disassembled, they will no longer work properly.

•

For BR-C6060-F, the power modulator is built into the brake body so a power modulator is not needed in the hub body. However, the special
front fork is needed to install it.

NOTE

•

Use a wheel with 3x or 4x spoke lacing. Cannot be used with wheels with radial lacing. Otherwise, the spokes or the wheel may be damaged,
or noise may occur when braking.

•

The INTER M brake is different from conventional band brakes in that the inside of the brake drum is filled with grease, causing the turning of
the tire to be slightly heavier than usual. (Particularly in cold weather.)

•

If you apply the front INTER M brake strongly while the bicycle is stopped and then shake the wheel, you will notice that there is a small
amount of gap in the brakes. This is normal, and will not cause any problems at all while riding.

7

TO ENSURE SAFETY

•

To check the amount of looseness in the head parts, grasp the middle of the handlebar
and one of the front forks as shown in the illustration, and then move the head parts
back and forth in the directions indicated by the arrows.
Moreover, because the brakes give a small amount of gap if you apply the brakes fully
and shake the wheel as described above, this will make it more difficult to check the
looseness in the head parts.

•

Products are not guaranteed against natural wear and deterioration from normal use and aging.

•

For maximum performance we highly recommend Shimano lubricants and maintenance products.

The actual product may differ from the illustration because this manual is intended chiefly to explain the procedures for
using the product.

After checking that the wheel does not
easily turn while the brake cable is
being pulled, depress the brake lever
about 10 times as far as the grip in
order to run in the brake cable.

Turn the cable adjustment barrel (A) of
the brake unit or brake lever so that
there is a 15 mm gap (a) (11 mm for
BL-C6010) in the brake lever.

(The amount of brake lever gap is the
distance from the position where the
brake lever is not operated to the
position where a force is felt suddenly
when the brake lever is pulled.)

After depressing the brake lever to
check the braking performance, secure
the cable adjustment barrel with the
cable adjustment nut (B).

NOTE

If the brake cable is not run in, it will need
to be adjusted again after only a short
period of use.
