North Shore Billet Disc Brake Adapter Post Mount

NEW: Please refer to our chart for the correct adapter size you need.

Disc brake adaptors available for Shimano, SRAM, Hope, Hayes, Formula, etc. rotors

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.

Not currently compatible with TRP 203mm rotors.
