Box Components Helix Qr Race Seatclamp

The Helix QR Seatclamp is cold forged and CNC machined from 6061-T6 Aluminium 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.
