Post Mount Disk Brake Adapters – North Shore Billet

High-quality disc brake adapters for almost any setup. Machined surfaces allow for better caliper alignment and a more rigid brake setup. Made in Whistler, B.C. and shipped worldwide.
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. Not currently compatible with TRP 203mm rotors.
