Box Helix Quick Release Seat Clamp
Box One Quick Release Seat Clamps are cold forged and CNC machined from 6061-T6 Aluminium alloy. A quick release lever makes adjusting your seat height quick and easy. Weighing just 28 grams / 1 ounce in the 31.8mm size, it's as lightweight as it is tough.
The head of the quick-release lever and the face of the clamp are given a proprietary “zero friction" surface treatment that ensures smooth lever action for the life of the clamp without the need for a bushing.
