Know before you buy
This adaptor acts as a bridge between your bike frame or fork and your disc brake caliper. It specifically offsets the caliper to accommodate a larger rotor size, ensuring the brake pads align perfectly with the braking surface.
While this is a genuine SRAM component designed for their specific post-mount standards, it is generally compatible with other brands that use the standard 40mm post-mount interface. However, always verify your specific rotor size and mounting configuration before installation.
You typically need a 40mm adaptor when you are increasing your rotor size by 40mm over the native mount size of your frame or fork. For example, if your fork is natively designed for a 160mm rotor, adding this adaptor allows you to run a 200mm rotor.
Yes, this SRAM adaptor typically comes with the required hardware to mount the adaptor to your frame or fork, and the caliper to the adaptor. It is recommended to check your specific packaging to ensure all hardware is present before starting your installation.
This depends on your frame and fork's native mount size. Because front and rear mounts often have different native rotor clearances, you should measure your current setup or consult your bike's manual to confirm if a 40mm offset is the correct size for your specific application.
