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 machining tool for milling both the outer edge and lower surfaces of the crown race 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
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
Always use cutting fluid such as Park Tool CF-2 when machining
