Important safety information
Important safety information
Because each bicycle may handle slightly differently depending on the model, 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 a loss of control or a fall, which
could lead to severe injury.
Do not disassemble or modify the product. This may cause the product to not operate correctly, and you
may suddenly fall and be seriously injured.
Do not apply the front brake too strongly. If you do so, the front wheel may lock and the bicycle may fall
forward, and serious injury may result.
Because the required braking distance will be longer during wet weather, reduce your speed and apply the
brakes early and gently. You may fall or collide and be seriously injured.
A wet road surface may cause tires to lose traction; therefore, to avoid this, reduce your speed and apply
the brakes early and gently. If the tires lose traction, you may fall and be seriously injured.
Do not allow any oil or grease to get onto the brake shoes. Riding the bicycle with oil or grease on the
brake shoes may prevent the brakes from operating and result in serious injury due to a fall or collision.
Do not use the brake cable if it has any rust, fraying, or cracks. Otherwise, the brakes may not work
correctly.
<Disc brake>
Please use extra caution to keep your fingers away from the rotating disc brake rotor. The disc brake rotor
is sharp enough to inflict severe injury to your fingers if caught within the openings of moving rotor.
Do not touch the calipers or disc brake rotor while riding or immediately after dismounting from the
bicycle. The calipers and disc brake rotor will become hot when the brakes are operated, so you may get
burned if you touch them.
Do not allow any oil or grease to get onto the disc brake rotor and brake pads. Riding the bicycle with oil
or grease on the disc brake rotor and brake pads may prevent the brakes from operating and result in
serious injury due to a fall or collision.
Check the thickness of the brake pads and do not use them if they have a thickness of 0.5 mm or less.
Doing so may prevent the brakes from operating and result in serious injury.
Do not use the disc brake rotor if it is cracked or deformed. The disc brake rotor may break, and result in
serious injury due to a fall. Replace the disc brake rotor with a new one.
Do not use the disc brake rotor if its thickness is 1.5 mm or less. Also do not use it if the aluminum surface
becomes visible. The disc brake rotor may break, and result in serious injury due to a fall. Replace the disc
brake rotor with a new one.

Important safety information
Disc brakes have a bed-in period, and the braking force will gradually increase as the bed-in period
progresses. Accidents or falls may occur due to losing control of the bicycle, possibly resulting in serious
injury. (The same thing will happen when the brake pads or disc brake rotor are replaced.)

Is the gap in the brake lever sufficient?
Does the brake cable have any rust, fraying, or cracks?
Have the brake shoes worn down to the grooves?
Do the brake pads have a thickness of 0.5 mm or more?
Are there signs of cracks or peeling on the levers?
Are there any abnormal noises?
