CNC machined from 6061 T6511 aluminum. Machined surfaces allow for better caliper alignment and more rigid brake set-up.

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

Some frames/forks use a 160mm rotor with no adapter, some use a 180mm with no adapter. Check your frame. These adapters can be used on both forks and frames with 160mm or 180mm posts.

Picking the Correct Adapter

To go from a 160mm post mount to 203mm rotor you will need a 203mm adapter.

To go from a 160mm post mount to 200mm rotor you will need a 200mm adapter.

To go from a 160mm post mount to 180mm rotor you will need a 180mm adapter and so on.

For 2016+ Fox 36 and 180mm rear brake mounts:

You will need the 180–203mm adapter to work with the 180mm post mount and a 203mm rotor.

Going from a 180mm post mount to a 200mm rotor requires the regular 180mm adapter.
