Something like this? http://m.pinkbike.com/news/article2106.html
Yep… they are both going in the right direction. Something along those lines has to be what displaces the POS rear derailleur/overweight cassette of our current bikes. The manufacturers are not rushing there, as they love selling us endless replacement drivetrains. The problem is getting the gearbox technology sorted to be 100% serviceable and robust and then getting commitment from bike manufacturers to build frames around that technology. Right now, they’d rather just sell us drivetrains. But one day… the dream will happen.or maybe a Zerode bike http://www.zerodebikes.com/
Switch the Pike for 36s and ditch the bottle cage and this would be my dream bike too. If I was in the market for one I'd look hard at an SB4.5 also.A Yeti SB5.5c with a bottle cage inside the frame. Full Di2 XTR, just a Pike & cheaper, quality carbon runs laced to CK hubs.
That would be my dream bike.
