Shimano XTR, XT disc brake adapter for 180 mm rotors - save a few grams


With the Shimano XTR and XT disc brake adapter for 180 mm rotors (SM-MA90) you can save a few valuable grams on your bike. This is because it has cut-outs that reduce its weight compared to conventional adapters. Of course it also works with other Shimano disc brakes and not only with the top groupsets for which it was developed. The adapter allows you, depending on the version, to mount a post mount brake caliper on an IS brake mount or to use a PM brake with 180 mm rotor on a PM frame for 160 mm direct mount.
