General Safety Information

• Check that the C-ring is inserted securely into the grooves of the pins on the disc

rotor adapter before riding the bicycle. If the C-ring is not inserted securely into the

grooves, the lock ring may loosen. If this happens, the disc rotor may come off and

the bicycle wheel may lock up or the brakes may fail to operate, and an accident

resulting in serious injury or death may occur.

• Disc rotors with diameters of up to 203 mm can be installed. If disc rotors with a larger

diameter than this are installed, the braking force may damage the main unit.

• Please use extra caution to keep your fingers away from the

rotating disc brake rotor during installing or servicing the wheel. The

disc rotor is sharp enough to inflict severe injury to your fingers if

caught within the openings of moving disc rotor.

• The calipers and disc rotor will become hot when the brakes are operated, so do not

touch them while riding or immediately after dismounting from the bicycle, otherwise

you may get burned. Check that the brake components have cooled down sufficiently

before attempting to adjust the brakes.

• The required braking distance will be longer during wet weather.

Reduce your speed and apply the brakes early and gently.

• 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.

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

the bicycle.

• Be careful not to allow any oil or grease to get onto the disc rotor and brake pads,

otherwise the brakes may not work correctly.

• If any oil or grease do get on the pads, you should replace the pads. If any oil or

grease gets on the disc rotor, you should clean the rotor. If this is not done, the brakes

may not work correctly.

• Vapor lock may occur if the brakes are applied continuously. To relieve this condition,

momentarily release the lever.

• Check that the quick release lever is on the right side (the opposite side to the disc

rotor). If the quick release lever is on the same side as the disc rotor, there is the

danger that it may interfere with the disc rotor, so check that it does not interfere.

• It is important to completely understand the operation of your bicycle's brake system.

Improper use of your bicycle's brake system may result in a loss of control or an

accident, which could lead to severe injury. Because each bicycle may handle

differently, be sure to learn the proper braking technique (including brake lever

pressure and bicycle control characteristics) and operation of your bicycle. This can

be done by consulting your professional bicycle dealer and the bicycle's owners

manual, and by practicing your riding and braking technique.

Vapor lock is a phenomenon in which the oil inside the brake system becomes

heated, which causes any water or air bubbles inside the brake system to expand.

This can then result in a sudden increase in the brake lever stroke.

• Obtain and read the service instructions carefully prior to installing the parts.

Loose, worn, or damaged parts may cause injury to the rider.

We strongly recommend only using genuine Shimano replacement parts.

• Read these Technical Service Instructions carefully, and keep them in a safe place for

later reference.

■ Burn-in period

• Disc brakes have a burn-in period, and the braking force will gradually increase as the

burn-in period progresses. Make sure that you are aware of any such increases in

braking force when using the brakes during the burn-in period. The same thing will

happen when the brake pads or disc rotor are replaced.

Note

• When using this disc rotor adapter to install disc rotors, the structure of the adapter

means that there will be more play than normal in the disc rotor. Because of this, the

disc rotor may interfere with the brake pads. Furthermore, it may also interfere with

the calipers in the radial direction (upward).

• If the brake caliper mounting boss and the dropout are not parallel, the disc rotor and

caliper may touch.

• If the disc rotor is worn, cracked or warped, it should be replaced.

• This product is not warranted against damage resulting from use such as jumping

while riding or if the bicycle falls over, except if such malfunctions result from non

conforming materials or manufacturing methods.

• Parts are not guaranteed against natural wear or deterioration resulting from normal

use.

• For maximum performance we highly recommend Shimano lubricants and

maintenance products.
