CNC machined from 6061 T6511 aluminum. Machined surfaces allow for better caliper alignment and a more rigid brake setup.

The Post Mount standard is universal to the front and rear brakes.

Frames and forks that use the post mount brake interface use a stock size that varies from 160mm–203mm. It’s important to check your frame and fork for the default post mount size before ordering a suitable adapter.

To calculate the size of the required adapter, subtract the frame/fork stock mount size from the desired rotor size.

If you’re using Magura MT5 or MT7 calipers please also order a low profile (button head) bolt to ensure correct fitment.

Our adapters do not come with mounting bolts but if needed, we have sets of 4 bolts available.
