All new brake pads and rotors should be put through a wear-in process called 'bed-in'. The bed-in procedure, which should be
performed prior to your first ride, ensures the most consistent and powerful braking feel along with the quietest braking in most riding
conditions. The bed-in process heats up the brake pads and rotors, which deposits an even layer of brake pad material (transfer layer)
to the braking surface of the rotor. This transfer layer optimizes braking performance.
The bed-in process requires you to perform heavy braking. You must be familiar with the power and operation of disc brakes. Braking
heavily when not familiar with the power and operation of disc brakes could cause you to crash, which could lead to serious injury and/
or death. If you are unfamiliar with the power and operation of disc brakes, you should have the bed-in process performed by a qualified
bicycle mechanic.
To safely achieve optimal results, remain seated on the bike during the entire bed-in procedure. Do not lock up the wheels at any point
during the bed-in procedure.
• Accelerate the bike to a moderate speed, then firmly apply the brakes until you are at walking speed. Repeat approximately twenty
times.
• Accelerate the bike to a faster speed. Then very firmly apply the brakes until you are at walking speed. Repeat approximately ten
times.
• Allow the brakes to cool prior to any additional riding.
