ORIGINAL SHIMANO SM-MA-F-D/D – HIGH-QUALITY FLATMOUNT ADAPTER FOR THE FRONT WHEEL (140 MM / 160 MM)
The Shimano SM-MA-F-D/D (SM-MA-F-D-D) is the original system adapter for all road bike, cyclocross, and gravel riders who expect maximum reliability from their disc brake. This precision-engineered adapter is specially designed for the front wheel (FW) and serves to mount a flat-mount caliper to forks that also feature the modern flat-mount disc brake mount. Thanks to the clever **flip-flop design**, the adapter is extremely versatile: by simply reversing it during installation, it can be quickly adapted to a brake rotor diameter of either **140 mm or 160 mm**.
Made from high-strength, torsionally stiff aluminum, the adapter easily withstands the thermal and mechanical stresses during hard braking maneuvers in the peloton or on dusty gravel roads. The perfect Shimano fit with the standardized 70 mm hole spacing guarantees an exact, absolutely parallel alignment of the brake caliper to the rotor. This effectively prevents unsightly brake judder, annoying rubbing, and uneven pad wear. Perfectly suited as a spare part or upgrade for performance brakes like the BR-RS505 and related flat-mount models.
