Rotor's new RVOLVER hubs bring genuine innovation

Spanish made road and MTB hubs with clever low-friction guts

BikeRadar has received details of an all-new range of road and mountain bike hubs from Spanish firm Rotor, and there's plenty of interesting tech to set them aside from what is an already crowded marketplace.

The RVOLVER range of hubs, which will officially be launched at Eurobike 2017, uses a unique clutch system to minimise friction when coasting, in a design that uses fewer internal components than a regular pawl and ratchet hub.

Inside, the clutch system moves — or “floats” — a ratchet ring away from the hub’s radial and angular pawls when the rider stops pedalling, thus disengaging the drive in an inventive way to reduce friction, and thereby decreasing rolling resistance and increasing coasting momentum. It’s something that’s demonstrated rather nicely in the following video from Rotor.

The ratchet ring connects to the hub’s shell without threaded parts, saving weight over a more conventional design. Rotor has boldly claimed that this unusual design makes the RVOLVER hubs the "easiest hub to install and maintain without the need for special tools."

The hubs are machined from 7075 alloy at Rotor’s facility, just outside Madrid, and all use standard J-bend spokes in a paired configuration. The rear hubs are quickly distinguished by their red anodised cassette bodies and are available with a standard or 2:1 spoke lacing pattern.
