Shimano XTR M985 Adapter
- Post Mount Calliper to IS Frame Mount is an interchangeable, precision engineered disc calliper mount adapter for post mount disc callipers to be mounted to international standard frames. Available in three rotor sizes. For 2011 Shimano has split the XTR range into two very distinct but still complementary ranges labelled ' Trail' & ' Race'. The best part though is that the XTR trail is the yin to the XTR Race's yang, & together mountain biking's first family of components offers a broad matrix of fully interchangeable options to tube your ride.
