Postmount brake caliper on a Flatmount fork? No problem.

The Shimano SM-MA-F140P/D Adapter allows you to mount a Postmount brake caliper on a Flatmount fork with 140 mm direct mount – in combination with a 140 mm brake rotor on the front wheel. Ideal if you want to reuse, for example, an existing MTB/Gravel Postmount brake caliper on a modern road or gravel fork with Flatmount standard.

The adapter is made of light, robust aluminum, and the included mounting bolts are made of steel. This gives you a stable connection with low weight. Perfect for road, gravel, or CX builds where you want to combine your braking system flexibly.

The SM-MA-F140P/D is specially designed for front wheel mounting and matched to a 140 mm rotor. This ensures the correct brake position, optimal piston alignment to the rotor, and consistent braking performance.

• Adapter Flatmount → Postmount: enables the use of a Postmount brake caliper on a 140 mm Flatmount fork.
