Shimano have redesigned their XTR XC race brake – now known as the M987. Significant weight savings have been introduced, along with a new rotor design offering improved heat dissipation.
The additional weight of many 29ers was a key consideration during the design process. Weight savings are claimed to be 40g per brake compared to the previous XTR Race M985, achieved by using a magnesium lever and caliper body along with carbon lever blades and titanium hardware. The range-topping M987 is actually Shimano's lightest hydraulic disc to date. The BR-M987 caliper is also compatible with Shimano's Ice Tech finned brake pads.
