To ensure proper headset performance and longevity, you must accurately machine the fork’s crown race (baseplate) seat. The CRC-1 is a professional-quality machining tool for milling both the outer edge and lower surfaces of the crown race (baseplate) seat.
Includes high-speed steel cutters and adjustable collets to machine 26.5mm and 27.1mm crown race seats on 1” forks and 30.1mm crown race seats on 1-1/8" forks
The unique adjusting system allows a tight fit of the tool on any fork, threaded or unthreaded (even forks with externally butted steerer tubes), ensuring a smooth, accurate cut and proper alignment of the fork in the frame
