I love my etap bikes. One tandem, one road bike. BUT, my road bike etap derailleur has failed. The failure was intermittent; try to shift and it wouldn't move. Not the batteries and maybe the server/motor (not sure of the terminology here). I called my LBS and they didn't bat an eye. Their report? Many etap failures are coming into the shop (as well as campy). Their advice? Stick with Di2 for now. Great. Can I get my money back?
