Post Mount Disk Brake Adapter

$30.00

Now Available!

203mm  » 220mm Post Mount adapters (+17mm). These work with 220mm rotors on 2015–2020 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 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.

 

The adapters do not come with mounting bolts.  Sets of 4 bolts are available HERE

Nice Product

Great service, fast shipping and an awesome product. Fit perfectly and did what it was supposed to do. Only one small complaint... Wish it had of come with a couple of the mounting screws. My original set up had only one long screw that went through the caliper and adapter and this mount required two short screws for the mount plus two more medium length screws for the caliper.. luckily I had just enough spares kicking around to get the job done.

More Hardware Please

Fits as expected. Would be nice if it came with some more hardware to mount.
