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.
Available in 31.8 and 34.9 in anodized Red, Blue, Gold and Black clamps with black levers and gold pivots, laser-etched graphics and Titanium hardware.
