Box One Quick Release Seat Clamps are cold forged and CNC machined from 6061-T6 aluminum alloy. A quick release lever makes adjusting your seat height quick and easy. Weighing just 28 grams/1 ounce in the 31.8 size, its 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.
