I have Felt bike - it had a problem - v.minor but it affected the line of the rear wheel, so quite an impact. Two photos and Felt sent my bike dealer a new frame - due to stock availability of my model/size it had to come from the U.S.
Took them a whole two weeks to give me a new frame, which was agreed overnight based on a couple of photos (and ultimately the returned frame I suppose). They upgraded the frame to the UHM from the HM Z35 to a Z25.
Felt after service is great. And that is not just because I got better frame, I was happy with the first one. They made a decision quickly, they told me the decision. They kept me informed of delivery and when it got to the UK they overnighted it to the dealer - who swapped the parts the day it arrived.
When you are spending that money a bike you want to know they will back it up- my experience says they will.
