Box QR Helix Seat Clamp 31.8mm
The Helix QR seatclamp is cold forged and CNC machined from 6061-T6 aluminum alloy.
A quick release lever makes seat height adjustments a snap.
Weighing just 28 grams/1 ounce in the 31.8 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.
