QR-1 seatpost clamps are cold forged and CNC machined from 6061-T6 aluminum alloy. 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 in the 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.
Available in 31.8 and 34.9 sizes in anodized red, blue, gold and black with laser-etched graphics and stainless steel hardware. Meets or exceeds ENM standards.
