Less Friction from Chosen Hubs
Chosen’s new smart hub features a new hub structure, which results in two major benefits compared to traditional hubs.
The first benefit is the reduction of the internal friction to a minimum and the second is the reduction of the rattle. The so-called Close Drive System closes the pawls when the hub is idle, easing the friction between pawl and ratchet teeth and reducing noise. The Smart hub comes in three rear versions and one front hub version.
