Post Mount Disk Brake Adapter

$34.00

Now Available!

203mm » 220mm Post Mount adapters (+17mm). These work with 220mm rotors on 2015+ Fox 40 and 49 forks with 203mm post mounts. 

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

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

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.

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 a 203mm rotor, you need a 43mm adapter.
  • To go from a 160mm post mount to a 200mm rotor, you need a 40mm adapter.
  • To go from a 160mm post mount to a 180mm rotor, you 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.

If you are using Magura MT5 or MT7 calipers please contact us with your order number so we can provide you with a low profile bolt to ensure correct fitment.

The adapters do not come with mounting bolts. We have sets of 4 bolts available.

Well built product

These are very well built and look great on the bike. I wish the variants for the different forks were laid out more clearly. Small detail for a great product.

amazing quality

the color is really great, and it is a well made part. I like how I don't have to use the long bolts from the shimano brake kit any more.
