I am 50, in good shape and live in mildly rolling hills in Ohio. I just bought a Merckx bike on Ebay and have the choice of Campy Chorus components or a Campy Triple. Since I have always rode traditional 10 speed bikes the thought of a triple kind of intimidates me. The seller, also 50, suggests the triple to help the legs on longer rides. I would appreciate any thoughts on the subject.
