BOX, Helix QR Seat Clamp

  • Sale
  • $ 28.95


Helix QR 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, 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.
