I have a 2014 Expert. Did 40 steep miles on it yesterday. Great bike. You will love it.

Someone above mentioned "ultra-twitchy handling". I don't get that at ALL. This is a very confidence-inspiring bike as far as handling.

That feeling stepping on the pedal and the bike wants to GO! is a legit one; I get it as well.

Just guessing, but since late November I think I've put 700-800 miles on mine. So far I have zero complaints or issues. The wheels have stayed true... everything works great... the 6800 is awesome...
