Promax QR-1 Quick Release Seat Clamp 25.4mm Blue. 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
