Custom CNC made headset compatible with Cannondale SI headtubes. (For example Jekyll, Trigger, Scalpel, Claymore, Moterra, Habit, Flash, F-Si, Rize, Taurine, Beast of the East...). No Headshok.
It fits in place of the 50.8mm outer diameter integrated bearings.
-2 degrees head angle change. When ordering, send me a message with the frames' head tube length measure.
If you have any questions just ask.
