I think sometimes it’s about how the combinations of frame characteristics and components come together that makes some bikes stand out over others. Probably the most disappointing bike I have owned was a Pinarello Montello. My first Basso Gap had a quick feel to it, nimble and easy to accelerate. It was a 56cm SL frame. My 54cm Gap does not have the same quality. The fastest speed I ever recorded on the flat was 25 mph on my 58cm Ciocc, before I mothballed it. It may not be super fast, but I love the ride qualities of my DeRosa.
