the Planetary clutch is the control mechanism for the hub. While going forwards it ensures minimal slack, while going backwards the clutch creates maximum slack. Magical huh? It's also much lighter than a traditional cone style freecoaster clutch. Patent pending
the 9t driver is similar to what you'd find on a cassette hub however it has sprung down pawls, this enables the hub to stay disengaged until you pedal forward. Also due to the mechanism of the hub the driver bearings are not under high axial loads like traditional freecoasters
