The Rotary Single is a new hub that replaces our Primary Single. It features the same overall look as the rest of the line, but the new appearance is just the beginning of the story. Now we use the well recognized bolts from the Rotary Pro hub with hex heads.

We decided to employ a female system in this hub. The steel thru-axle with nuts was replaced with a lighter and stronger oversized alloy 7075 axle and steel bolts. In other words this hub uses the same system that proved itself in our Rotary Single Pro rear hub. The female axle system will immobilize the wheel in the dropouts no matter what, and there is much less chance to hurt your ankles on the bolts. Designed for pegless riding. Overall, we managed to produce an incredibly light and strong hub in an economical price range.
