QR-1 seatpost clamps are cold forged and CNC machined from 6061-T6 aluminum alloy, then polished, anodized and precision laser etched. The QR-1, as the name implies, has a quick release lever, making seat height adjustments a snap. Weighing just 30 grams/1.1 ounces (31.8 size), it's as lightweight as it is tough. The head of the lever and the face of the clamp are given a proprietary low-friction surface treatment that ensures smooth lever action for the life of the clamp without the need for a bushing. Laser-etched graphics and stainless steel hardware put the finishing touches on this snazzy seat collar. Understated, yet an excellent value.
