Seat Clamp Quick Release, Brass

This is the brass version of our Seat Clamp Quick Release—combining elegant design, exceptional functionality, and low weight.

The newly redesigned concave washer ensures the lever handle stays put—it consists of two parts: a base to secure the lever handle in place, preventing rotation, and a concave insert. Crafted from POM, a low-friction, self-lubricating material, this insert allows smooth opening and closing of the quick release. We've also lengthened the lever handle and enlarged the cam, delivering ample clamping force.

While the brass version is slightly heavier than the aluminium version, it still sheds about 19 grams compared to Brompton's seat clamp quick release.

Every aluminum component is CNC machined from 6061-T6 aluminum, while the axle and barrel nut are made from titanium grade 5.
