i've similar sentiments. no denying cedric's ingenuity, & to bring a truly novel drivetrain to production in such a short timeframe, with relatively limited resources is an impressive feat - i wish him well. but as effective this specific implementation may be, there's just a lot stacked against this becoming a sustainable alternative. lots of proprietary bits is certainly one (big) thing, but requiring a dedicated frame build with severe restriction of suspension layout / kinematics is not a route to mainstream adoption. alas, time will tell.
what really gets me excited these days is what trinity / williams racing are up to. rad mech in a box implementation, as well as a platform with a more or less universal drivetrain cradle that will accommodate their own box, as well as pinion, effigear, and conventional drivetrains - on the same bike. brilliant stuff.
