I've had wonderful luck with my Trek's. Nice bikes.. right down to the 7200wsd that my significant other rides. It does the job.

They've performed true to their specs and if there was a problem it was due to human failure on my part as a rider.

Key is to have the bike fit for you so when your out there riding you don't even notice the bike beneath you. On Trek's I've reached the point of "ZEN" where I forget the bike is beneath me and all my attention goes outwards towards my surroundings. This doesn't include that incident 30 years ago while working as a messenger I got doored and flew through the air headfirst into a horses ass.
