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 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.
