The Promax "QR-1" BMX Race Seat Clamp - Quick Release is a light quick release seat clamp for frames with a round seat tube. The lever lets you set the saddle height without tools, and it still clamps firmly. Promax forges it from 6061-T6 aluminum and CNC machines it afterwards. Measure the correct diameter on the outside of your seat tube with the seatpost inserted. Choose the colour as an option.
