I am considering an upgrade to my frame. Currently a 2005 trek Madone, and considering a 2010 5 series madone. What I am wondering is, will I notice the difference and will it make me a better cyclist? I am new to racing (crits), cat 5, but have won a cat4/5 race and doing great in sprint laps, generally win them, or split with one other guy. I followed a cat 2 (didn't know until after the race he was a cat 2) in a race through super fast tight corners while the rest of the pack went way wide. So do I keep riding and getting better on my current bike, with absolutely nothing wrong with it, fits perfect, never sore in places I shouldn't, or spend a bunch of money on a new frame? What would I gain/how would it help me in being a better cyclist?
