Post Mount Disk Brake Adapter

$38.00

NEW: Please refer to our table graphic in the images for the correct adapter size you need. 

Disc brake 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 for front and rear brakes.

Frames and forks that use the post-mount brake interface use a stock size varying from 160mm to 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.

If you’re using brakes with large calipers (Magura MT5/MT7, Hope Tech V4, Hayes Dominion A4 etc.), please also order a low profile (button head) bolt kit to ensure correct fitment.

Our disc brake adapters do not come with mounting bolts but if needed, we have sets of 4 bolts available.

NSB Great products

All good, with 2 comments: 1- it seems that the old 40mm PM adaptor was thicker and Hope calipers don’t sit well on it. The new version is thinner and worked for me. 2- the old gold color was better :)
