Mountain Bike Disc Brake Rotors

Replacing a worn rotor or fine-tuning your braking setup? Shop MTB disc brake rotors from SRAM, Shimano, Magura, Hope, TRP and more. This collection includes 6-bolt and Center Lock options in a range of diameters.

Match the Mount, Diameter and Thickness

Start with your hub's rotor mount, then check the rotor diameter and thickness supported by your brake, frame and fork. Match the rotor's pad compatibility to your brake pads as well. Similar-looking rotors aren't necessarily interchangeable, and a larger rotor only makes sense when the rest of the setup supports it.

Changing Rotor Size?

You may also need a different disc brake adapter. Check the exact rotor size and mounting requirements rather than assuming every size change uses the same adapter. For Center Lock setups, confirm the lockring and axle compatibility and whether the required hardware is included.

For a complete brake upgrade, browse our mountain bike disc brakes. If the fit is unclear, send us your brake model, current rotor size and bike details. We'll help you sort out the right combination before you order.
