Lightest ever Shimano hydraulic disc brake system. Shimano debuts its lightest hydraulic disc brake system ever to the XTR line. Race rated to match the power and control of the M985 Race brake while dropping weight by 40g per wheel, the M987 disc brake will surpass rider expectations for a lightweight brake. Shimano engineers incorporated the use of a magnesium caliper and master cylinder construction in the new XTR BR-M987 to drop weight while maintaining system stiffness and control by properly managing heat.
The new, lighter BL-M987 hydraulic disc brake lever lightens up thanks to carbon fiber lever blades and titanium fasteners. The BR-M987 caliper is compatible with ICE Technologies finned disc brake pads and the BL-M987 lever is I-spec compatible.
