North Shore Billet Disc Brake Adaptor

CNC machined from 6061 T6511 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.
