Park Tool Crown Race Cutter Adaptor One Color, One Size

In order to maximize the lifespan and performance of your headset, you'll want to cleanly face the crown race seat for a precise, low-tolerance fit. The Park Tool CRC-1 Crown Race Cutting Tool does just that, but it requires an adaptor for 1. 5in tapered steerer tubes. This is that adaptor. It includes a precision-machined adaptor body as well as a high-speed steel crown race cutter. Please note that it only works on forks where the tapered area of the steerer tube is a maximum of 4. 25-inches in length.
