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.

• The Post Mount standard is universal for front and rear brakes
• 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

Notes

• NSB disc brake adapters do not come with mounting bolts. 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
• Not currently compatible with TRP 203mm rotors
• Due to inconsistencies in anodizing, the pewter you receive may be different than the pewter you see on screen or different from other pewter NSB items you may already own
• NEW: Please refer to NSB's table graphic in the images for the correct adapter size you need
