TRP - Tektro Post Mount PM ROTOR ADAPTER
If you have a PM 180 fork, like a FOX 36, and you would like to run a 203mm rotor, you will need to lift the caliper 23mm, which will be the P23 adapter. If you would like to run a 220 or 223mm rotor, you will need to lift the caliper 40-43 mm, which will be the P40 adapter. Please follow the chart to pick your correct adapter.
To go from 220 to 223, add 1-1.5mm washers under the caliper.
