The Rotary cassette Boost is a high end mountain bike cassette hub with a thru axle system that will keep the rear end of a frame much more stable. The hub is designed to work with 148x12mm frames. It’s light enough for racing and strong enough to take big jumps. This hub is fully sealed, runs on 4 bearings and features an oversized AL7075-T6 axle. To make sure the hub will hold up any kind of abuse, we used the best AL7075-T6 for our hardware. Intended use: Snabb Plus, Eccentric Cromo 29”, Eccentric Djambo Evo and other BOOST frames.
