SM-MA-R180 P/S for Post mount caliper / SI frame Adapter
$24.00
The Shimano SM-MA90-R180P/S is a precision-engineered adapter that allows the mounting of a Post Mount disc brake caliper to a frame with International Standard (I.S.) tabs. This specifically adapts the rear of the bike to accommodate a 180mm rotor.
By shifting the caliper position, this adapter ensures proper pad alignment and optimal braking surface contact. It is an essential component for riders upgrading their rear rotor size or modernizing older frames with I.S. mounts.
