Details
Here it is, a new and improved version of Brompfication's Seat Clamp Quick Release! With several new design features the Seat Clamp Quick Release is not only the lightest and most attractive, but also one of the best functional available.
The lever handle is prevented from rotating with a new re-designed concave washer, that consist of two parts - a base that holds the lever handle in place so it doesn't rotate, and a concave insert. The concave itserts are made from low friction and self lubrication material called POM, that make it possible to open and close the quick release with ease. The lever handle is also made longer and the cam bigger, providing plenty of clamping force.
These improvements are all done without sacrificing on the low weight. At only 21 grams, Brompfication's Seat Clamp Quick Release saves 34 grams over the original! The brass version is a bit heavier, but still saves you about 19 grams. All aluminium parts are CNC machined from 7075-T6 aluminium, and axle and barrel nut and made from titanium grade 5.
- Aluminium Version: 21 grams
- Brass Version: 38 grams
