The Shimano SM-MA-F140P/D and SM-MA-F160P/D adapters allow you to mount standard 74 mm post-mount brake calipers onto flat-mount front forks. The 140P/D version is suited for 140 mm rotors, while the 160P/D model fits 160 mm rotors, ensuring a smooth setup when adapting caliper standards.

Designed for Seamless Integration: These adapters are engineered for front brake use and provide a solid interface between caliper and rotor. Each adapter includes the required bolts and hardware, making installation straightforward and reliable. The fit is precise, maintaining alignment and rotor clearance even under high braking forces.

Lightweight and Durable Construction: Made from high-grade anodized aluminum, the adapter is strong and lightweight. The steel hardware ensures a secure hold during braking and the compact design blends cleanly into modern road and gravel bike builds without adding bulk.

Installation Made Simple: Installation is easy with standard tools and Shimano recommends torqueing the bolts to 6–8 Nm. For added safety, securing bolts with snap rings or safety wire is advised to prevent loosening from vibrations over time. Once installed, the setup offers consistent and dependable performance.

It's an ideal choice for cyclists upgrading or tuning their brake system to match changing rotor sizes or frame standards without compromising on quality.
