Shimano MA90 R180P/S Disc Brake Adaptor for 180mm Rotor Info
The Shimano MA90 R180P/S Disc Brake Adaptor for 180mm Rotor is a direct-mount adapter designed to run a 180mm rotor on a post mount brake caliper. A straightforward, precise-fit component from Shimano — built to the same tolerances you'd expect from the rest of their brake system.
If you're upgrading to a larger rotor for more stopping power or replacing a worn adapter, this is the correct fitment for post mount forks and frames. Shimano-spec hardware means reliable alignment and consistent caliper positioning out of the box.
