Disc Brake Adapter PM

Adaptors available for Shimano, SRAM, Hope, Hayes, Formula etc. rotors:

• 180mm
• 183mm
• 185mm
• 203mm 
• 220mm

CNC machined from 6061 T651 aluminum. Machined surfaces allow for better caliper alignment and a 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/fork! Our adapters can be used on both forks and frames with 160mm and 180mm posts. Bumping up from a 203mm post mount (2015–2020 Fox 40 and 49 forks) to a 220 or 223mm rotor is also covered by our adapters. 

PICKING THE CORRECT ADAPTER

• To go from a 160mm post mount to 203mm rotor you will need a 43mm adapter.
• To go from a 160mm post mount to 200mm rotor you will need a 40mm adapter.
• To go from a 160mm post mount to 180mm rotor you will need a 20mm adapter and so on. 
• For 2016+ Fox 36 and 180mm rear brake mounts: 
• You will need the 23mm 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 20mm adapter.
