Cari, the Trek has a Bonrager Race crank (52/39/30) with a Shimano 105 12-25, 10 speed cassette. The Ruby comes standard with an FSA Gossamer compact crankset and a Shimano 105, 12-27, 10-speed cassette. I would have the compact swapped for the Shimano 105 triple.

We live in north Georgia, which is hilly, and I doubt that I'll be touring, but think that my "mature" knees would be happier with the triple. In fact, my LBS suggested that I take my current bike (which has a triple) out to a hill that I normally use my granny gear to climb and stop shifting when I got to my second-to-last gear to see how it felt. I did that, and although I got to the top of the hill, it was slow and difficult.
