Stan's NoTubes ZTR Alpine Disc MTB Rim

Stan's NoTubes ZTR 330g Alpine rim is perfect for every rider who craves low weight, high performance race rims. The ZTR Alpine also receives the first implementation of Stan's next-generation BST (Bead Socket Technology), resulting in a rim that doesn't have a bead hook, which lowers the sidewall of the rim by 2-3mm.

The ZTR Alpine has a wider inside rim cavity with shorter sidewalls, which means improved tire performance at equivalent pressures as well as decreased pinch flats. With these short sidewalls, the tire should not hit the rim and pinch flat as often when tubes are used. This design will allow you to run lower pressures and use 4mm more of the tire than ever before.

The curve of the rim sidewall is the same shape as the bead of the tire, so they fit together like a ball and socket joint. This design will help reduce the strain on the tire bead while creating a tighter seal.

Fully tubeless compatible when used with Stan's Yellow Rim Tape and Stan's 35mm Mountain Valve Stem.
