The 2.3 trek is 50/34 with a 11-25 cassette.

I'm riding a 53/39 with either a 11-25 cassette (on my Bontrager race wheels) and a 12-27 cassette on the American Classic wheels. (I'll likely flip flop the cassettes for tri racing season). This takes me over all the hills that I do around here. Except the 25% (is that what it was) alley that Mr. likes to do. I'm too afraid to try.
