Brembo GR-PRO Disc Brake Adaptor

The Brembo GR-PRO adaptor positions the GR-PRO caliper for the rotor size your frame or fork requires. Choose the +20mm or +40mm version by checking the native mount size and your intended rotor diameter, rather than choosing by rotor diameter alone.

The shaped bracket and version-specific mounting hardware locate the caliper for the chosen rotor size. Confirm the frame or fork's mounting specification and maximum rotor size before fitting.
