I posted this in another forum and haven't really decided yet between buying a new Trek 1500 with a triple, double or compact double crankset. I ride 12 miles a day over some hills in central mass on my current bike, a Trek 720. and don't use the small ring of the triple. I think the extra top end for the double is not worth losing some low gears, but the compact intrigues me - because of the crisper shifting and extra gearings on the low end. I compared gear-inches for the lowest gear I ride on the Trek 720 to the lowest gears for a compact double and find that I would only lose, by a fraction, the lowest gear. In summary, I am leaning towards the compact, the area I ride in is hilly but not mountainous, and I'm 55. Oh yes, I probably will upgrade in a few years to a more top of the line bike.
