Fox Factory has filed a patent titled “Suspension Enhancing Hub and Rear Derailleur Assembly”, outlining two separate but related inventions designed to eliminate the negative effects that chain tension exerts upon a bicycle’s rear suspension and ride feel.
A rear derailleur with an electronically actuated clutch mechanism deals with chain tension between the chainring and the derailleur, while an automatic electronic decoupling hub assembly deals with chain tension created between the chainring and the cassette. In the patent, both components are described as being controlled by sensors detecting important information about the ride, such as gradient, pitch of the bike, and suspension action, while the possibility of an “over-ride” is also described that could allow the rider on-the-fly control over the behavior of the components.
It’s a “no-comment” from Fox on this one, but we’ll certainly be keeping an eye out for these components come the opening ro...
