TRP CNC Post Mount Brake Adapter
The TRP CNC Post Mount Brake Adapters use a simple and easy approach to help you get the correct fit. "P" stands for "Plus", immediately followed by the millimetres needed to elevate the caliper to your chosen rotor size.
If you have a fork with 180mm post mounts, like a FOX 36, and you would like to run a 203 mm rotor, you will need to lift the caliper by 23 mm. For this you would need the P23 adapter. See the chart in the images to help you choose the correct adapter for your needs.
