Lower friction when coasting so you roll farther on accumulated momentum

Rotor RVOLVER Hub Technology

By utilizing a clutch-type system and floating the ring, you lower friction when coasting so you can roll farther on accumulated momentum.

Rotor has long been a bastion for alternative ideas. They made their name selling oval chainrings to an industry that’s forever revolved around round. And now the Spanish company is taking aim at the hub market.

Their new RVOLVER technology utilizes radial pawls in the freehub body that engage a floating ratchet ring with a less than 15° engagement angle to react (they say) instantly to pedaling force without losing velocity. The idea is that utilizing a clutch-type system and floating the ring, you lower friction when coasting so you can roll farther on accumulated momentum. Press play to see the unique hub in action.

Rotor also claims that by connecting the ratchet ring to the hub shell without threaded parts significantly lowers RVOLVER’s weight, and sealed bearings and fewer internal parts make it easier to install and maintain without the need for special tools.

RVOLVER’s flange design features evenly spaced, notched flanges to reduce overall weight and allow for easier wheel assembly. The flanges also offer tailored hub shells for a standard or a 2:1 spoke lacing pattern. The hub’s multi-compatibility design means that it’s compatible with most frames and forks currently available. At launch the hubs, which are CNC machined from 7075 aluminum near Madrid, will be available in traditional road and 6-bolt disc rod, and 6-bolt MTB. Availability is set for October 2017.

    Late’s see; hardend steel pins cycling in and out of an aluminum freehub body many thousands of times…under load….what could possibly happen?

    Was it just me? It looks like as it is free-spinning a gap opens up between the red part and the black part

    Looks like an invitation for dirt etc to get inside. Just a thought though, maybe just a bad angle
