Park Tool Headset Crownrace Cutter CRC-1

To ensure proper headset performance and longevity, special attention must be given to accurately machine the fork's crown race seat. The CRC-1 is a professional-quality tool for machining both the outer edge and lower surfaces of the crown race seat. Its unique adjusting system allows a tight fit of the tool onto any threaded or unthreaded fork - even forks with externally butted steerer tubes - ensuring a smooth, accurate cut and proper alignment of the fork. Includes two sets of high speed steel cutters and adjustable bushings to machine forks with both 1" and 1 1/8" steering columns.
