TRP have thought this one out, and that's why it's our choice of centerlock adapter to keep your brakes locked in when you need them!

The combination of low profile, chamfered Torx bolts mating to to the disc compression-plate gives a flat surface for the lock-ring to fasten against. Which has opened up the design up to implement the larger lock-ring profile, which allows the use of an Shimano type cassette tool for fastening, allowing you to really torque the disc-mount up compared to other designs with a smaller fastening system.
*Not compatible with axle/cone hardware with a 20mm or larger diameter.

**Requires 12-spline Shimano type cassette tool with an approximate outer diameter of 23.4mm
