Chromag Quick Release Seat Collar


The Chromag Quick Release seatpost clamp features a unique bushing that contacts the entire cam surface for the smoothest, most powerful action possible.

The combination of a precision brass bushing and the smooth cam action of the lever makes for the most enjoyable lever experience. The brass bushing is precision machined to press-fit perfectly into the collar and mate with the lever cam. A custom Chromag 6mm bolt ensures reliability.

CNC machined in Canada.
