Promax QR-1 Quick Release Seat Clamp

Availability: In stock

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.
