Know before you buy
This adaptor is designed to correctly position your flat mount brake caliper to accommodate a 160mm rotor on a frame that would otherwise be set up for a smaller rotor size.
No, this specific adaptor is engineered exclusively for 160mm rear rotors. Using it with a different rotor size will result in improper caliper alignment and compromised braking performance.
While this adaptor is designed to integrate seamlessly with SRAM flat mount systems, it is intended for use with standard flat mount calipers. However, for the most reliable performance and precise fit, we recommend using it within a complete SRAM braking ecosystem.
No, this component is specifically engineered for rear flat mount configurations. It is not compatible with front fork mounting standards.
The adaptor typically includes the necessary hardware for mounting the caliper to the bracket. Ensure your frame's mounting bolts are in good condition, as you will reuse the existing bolts to secure the adaptor to the frame.
