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.
