I ride the Trek 7.5. Mine is a 2014 and I have 1500 miles on it. I think it is a great riding bike and I enjoy it every time out. Handles well, reasonably fast and smooth. Mine has a carbon fork and the Iso-zone rear seat stay. It makes a difference on bumpy surface. Mine is stock and the components function perfectly. I have the stock 28mm tires which I find are great combination of speed and ride. I haven't even changed the cassette. I find the gear range very good with the compact drive. The only negative I can think of is I am not too wild about the seat. Overall I highly recommend it. You can't go wrong with the 7.5 FX.
