Commonly paired with Hope&';s Floating Rotor which are 1.8mm thick. Also compatible with Hope&';s Vented Rotors which are 3.3mm thick. We highly recommend using Hope brake adapters because the oversized calipers can cause compatibility issues with non-Hope brake adapters. Replacement brake pads can be found here!
