Hello,

I recently saw the 2013 Trek 7.7 FX at our LBS and I was very impressed. Other than the dual crank vs the triple for the 7.9 FX, is there any major differences between these two bikes? Also, if I'm considering chosing between a 2010 7.9 FX almost new and a new 2013 7.7 FX, which one would be a better bike? Your thoughts please.
Thanks.
