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?
eTap stops responding mid-ride
I had this problem. Did extensive diagnostics while living with it. Eventually decided I could no longer live with it, after bike refused to shift climbing a 16% grade on a ride I was doing for time.
Involved my LBS, they contacted SRAM, who sent a replacement rear der (which is the brains for the whole system).
Problem resolved, that bike has not acted up since.
Now my OTHER eTap bike, which had previously performed well all year, has started exhibiting the same symptom 2-3 times on the trainer this winter. So far it has self corrected each time by shifting the front, but I suspect I will be pursuing a warranty replacement for it shortly.
My main takeaway is "Thank god SRAM killed the offshore channels and I had no choice by to pay a couple hundred more through my LBS. THIS time, the warranty has proven valuable."
