The BSD Revolution Planetary is a freecoaster hub based on the Planetary technology. It sounds crisp and engages instantly, yet it does not block the wheel when you ride backwards. Truly, Planetary hubs merge the most loved properties of cassettes and freecoasters in one single hub. With this hub it will be possible to assemble a very strong wheel with 36 spokes. Hubs with male axles like this one are tightened to the dropouts with a nut.
