Hayes Disc Brake Adaptor

Yes, this is a universal post-mount to post-mount adapter, meaning it is compatible with most standard post-mount brake calipers regardless of the brand, provided your frame or fork uses the standard post-mount interface.

This adapter is specifically designed to space your caliper out to accommodate a 203mm rotor. It assumes your frame or fork is currently set up for a smaller rotor, typically 160mm, and provides the necessary +43mm offset to bridge that gap.

No, the adapter comes with the necessary mounting bolts included in the package. You should have everything you need to bolt the adapter to your frame or fork and attach your caliper to the adapter.

Yes, this adapter is designed for post-mount configurations and can be used on either the front fork or the rear frame mount, provided the mounting standard matches the post-mount design.

Hayes engineered this adapter with specific attention to structural rigidity, which is critical when dealing with the increased leverage of a 203mm rotor. It ensures your caliper remains perfectly aligned under heavy braking loads to prevent vibration or uneven pad wear.
