The Trek 7.6 has a triple - at least the 2010 model did - I had one There are people totally sold on road drop bars, but I find flat bars with Ergon grips to be 'da bomb" - I can ride this all day long with no hand problems and I've arthritis in my hands (my longest ride so far as been 75 miles). Of course it matters that the bike is fit properly to you.

That being said, just as I can't ride road drop bars, there are some who cannot ride flat bars regardless of grips or how the bike is setup.

I can't speak about the other models, but the Trek is a nice flat-bar road bike and wouldn't be a bad choice if it fits you. You will want to see what model year it is since it sounds like newer versions are now compact doubles rather than a triple chain ring.
