NS Bikes Rotary Rear Cassette Hub

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 alloy 7075 axle. The hub is held securely by 3/8” steel bolts with rounded flat bolt heads that are almost flush with the dropouts so there is little chance to hurt your ankle.

The advantage of oversized alloy axle and steel bolts is significant: there is no weight penalty and bolts have 8mm 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 alloy for our cones and we even reinforce them with steel inserts.
