TRP P-Series Brake Adapters

TRP's new adapters use a simple and easy approach to help you get the correct fit. “P” stands for “Plus”, immediately followed by the millimeters needed to elevate the caliper to your chosen rotor.

If you have a PM 180 fork, like a FOX 36, and you would like to run a 203 mm rotor, you will need to raise the caliper 23mm, which will be the P23 adapter.
