Hello all. I'm 53, semi-in-shape, and new to road biking. I rode a road bike when I was a kid but it was a steel tubed cheapie. My new bike is a 2011 Trek Madone 5.2 with the triple crank option. I live in a pretty hilly area, California Central Coast, and even with the triple crank, at times I could use a few more teeth in the cassette. I currently am running the stock 11-28 105 cassette. Could I use a 11-32 xt cassette without having to change my derailer? Is there another cassette option that would work? I'm guessing I'd have to replace my chain too?
Thanks for any replys. I'm really loving getting back on the roads.
