The Rotary cassette is a high end mountain bike cassette hub with a female axle system that will keep the rear end of a frame much more stable, and can be used in horizontal dropouts without any axle positioning systems. It’s light enough for racing and strong enough to take big slopestyle jumps. This hub is fully sealed, runs on 4 bearings and features an oversized AL7075-T6 axle. The hub is held securely by 3/8” steel bolts compatible with 10mm dropouts. The advantage of oversized aluminum axle and steel bolts is significant: there is no weight penalty and bolts have 6mm hex sockets so you can tighten your rear wheel with an Allen key. To make sure the hub will hold up any kind of abuse, we used the best AL7075-T6 for our cones and removed the steel inserts that we used before.
