The Race’s master cylinder uses the same high polish piggyback reservoir design as its XTR stablemate, the Trail (M985), but with the bore cap on the reservoir screwed in to reduce capacity (and weight) and only small Allen key reach adjust on the lever.
It’s not a ﬂip-ﬂop design and it’s heavier than other ﬂagship race brakes but the hinged bar clamp makes ﬁtting easy. Feel from the short lever blade is superb – slightly squeezy but with outstanding modulation and ﬁne control of its average power. The four-arm-spider ICE rotor (140mm size; the larger sizes, as pictured, are five-arm) uses a high-tech sandwich construction to reduce heat build-up.
However, our sample was fading at the end of the 150N pull sequence. The ICE rotor is only available in a Center Lock splined version which limits it to Shimano and DT Swiss wheels. It’s sold as separates so you can swap to a standard six-bolt XT rotor if you’re not going to cook it too hard.
