The M987 Race Disc brake is light. Shimano has redesigned it to produce great weight savings, along with a new rotor design for better heat dissipation. Weight savings are 40g per brake compared to the previous XTR Race M985. Top of the line and super light, the M987 is Shimano's lightest hydraulic disc brake to date.

Showing Questions 1 of 1
Q: I have a Cannondale Scapel 29" with inferno 25 wheels I want to buy the XTR disc brakes And I have few questions 1- will it fit on my bike? 2- which rotor would you recommend? The XTR? 3- I have a lefty as a front shock, will it fit in the front wheel? 4- will it fit on my rear too? Thanks for the attention.
A: Yes, Shimano hydraulic disc brakes are compatible with most modern mountain bicycles, and thus these XTR Race brakes should work fine with your Cannondale Scalpel (provided you have the appropriate adapters). If you aren’t sure which rotor size to run, you may want to conform with what originally came with your bicycle (typically 180mm front, 160mm rear). Larger rotors offer greater stopping power than smaller ones, but are heavier. Please note, certain frames can only accommodate certain sizes, so you should check with Cannondale on the maximum allowable rotor size for your bike.
