Post Mount Disk Brake Adapter

Regular price $36.00

NEW: Running a 220mm+ rotor and have a fork with a 200mm or 203mm direct mount (Zeb, 2021+ Boxxer, 2021+ Fox 40) requires our updated 20mm and 23mm adapters marked with a ‘*’

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

  • 180mm
  • 183mm
  • 185mm
  • 203mm
  • 220mm
  • 223mm

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.

Picking the Correct Adapter
  • Going from a 160mm post mount to a 203mm rotor requires a 43mm adapter.
  • A 160mm post mount to a 200mm rotor requires a 40mm adapter.
  • A 160mm post mount to a 180mm rotor requires a 20mm adapter.
  • 2016+ Fox 36 and 180mm rear brake mounts:
    • A 23mm adapter is required to use a 203mm rotor.
  • A 180mm post mount to a 200mm rotor requires the regular 20mm adapter.
  • 203mm » 220mm post mount adapters (+17mm): These work with 220mm rotors on 2015–2020 Fox 40 and 49 forks
  • Rockshox Zeb and 2021+ Boxxer forks are 200mm direct and require NO adapter to run a 200mm rotor.
    • Using 220mm and 223mm rotors with the RockShox Zeb and 2021+ Boxxer requires our updated 20mm and 23mm adapters marked with a ‘*.’
    • Using 220mm rotors with 2021+ Fox 40 requires our standard 17mm adapter. Using 223m rotors requires our updated 20mm adapter marked with a ‘*.’

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

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

Great look but IMO a little too big

I made sure I got the right size for a fox 38 180 post mount to 203mm rotor. On the website it will the 23mm size adaptor. 180+23=203, makes sense. When it came it's well designed and has a great look but IMO it pushes the brake calliper too far out and the pads do not contact all of the rotor. I put on a new rotor and pads, so I can see where the wear is starting and it's definitely not contacting all the braking area of the rotor. Still, I'm stopping well so I'm going to see how it goes, maybe I'm wrong.

Great workmen ship

I emailed asked questions about which break adapter I need. I received the answer quickly. Fantastic for sure. The only thing was shipped slow. But I was not in a rush just a observation. Thanks for everything I’ll be getting more products from you. Thanks Troy

perfect fit

i bought some mahoosive 223 Galfer rotors for the eeb and used the 43mm NSB post mounts, allowing for a perfect fit with the least amount of messing about. the NSB colour tones are awesome, love their gold.
