ORIGINAL SHIMANO SM-MA-R160P/D – HIGH-QUALITY REAR BRAKE DISC ADAPTER FROM FLATMOUNT TO POSTMOUNT (160 MM)
The Shimano SM-MA-R160P/D is the original system adapter for all gravel, road bike, and cross-country riders who demand maximum flexibility in component selection. This precision-engineered adapter is specifically designed for the rear wheel (HR) and bridges the gap between different brake standards. It allows for the straightforward mounting of a proven Postmount brake caliper (PM) to modern frames featuring a Flatmount 140 mm direct mount. At the same time, it enables the upgrade to a **160 mm brake disc** at the rear.
By switching to a 160 mm rotor at the rear wheel, you immediately benefit from noticeably more braking power, finer modulation, and significantly improved heat management during long descents or fully loaded bikepacking tours. Made from high-strength, torsionally rigid aluminum, the adapter confidently absorbs enormous shear forces during hard braking maneuvers without distortion. The proverbial Shimano precision guarantees an exact parallel alignment of the brake caliper to the rotor, which highly effectively prevents unpleasant rubbing, annoying brake judder, and uneven pad wear.
