The Promax QR-1 seatpost clamps are cold forged and CNC machined from 6061-T6 aluminium alloy. The QR-1, as the name implies, has a quick release lever, making seat height adjustments a snap. Weighing just 30 grams 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 31.8mm and 34.9mm, these fit most pro frames that run a 27.2mm and 31.6mm seat post, they come in anodised red, blue, gold and black with laser-etched graphics and stainless steel hardware.
