Race rated to match the power and control of the XTR M985 Race brake while dropping weight by 40g per wheel, the Shimano XTR M987 XCR disc brake will surpass rider expectations for a lightweight brake. Shimano dropped weight by using a magnesium caliper and master cylinder with a carbon fiber lever blade and titanium fasteners. Underpowered brakes lead to defensive riding technique and, ultimately, to slower lap times. Enter the new XCR Race brake, which encourages racers to attack technical downhill sections with confidence, leaving the competition in the dust. Heat buildup is the enemy of any brake system, but the Shimano XTR M987 XCR disc brakes aluminum-backed brake pads and the industry's first full ceramic caliper piston help to dump heat and maintain consistent power. Each individual brake comes with brake lever, and caliper. Rotors are not included.
Hint for breaking-in: New disc brake pads require a certain break-in period in order to provide the full brake power. The following procedure has proved oneself: drag braking on a downhill until the brake power noticeably increases. Then let the brake rotor cool out. Afterwards do 20 full stops braking from a medium speed. Attention: the rotors get very hot, do not touch them!
