I am a avid mountain biker, (got 5 MT Bikes) and no road bikes. but after last cat 1 race and pressure from my friends i realize i need to get on a road bike to build endurance.I am looking at getting building a tarmac pro w/ campy chorus 11 speed, campy wheels and other odds and ends. The shop that sponsors me has a Pinarello FP3 w/ 10 spd Dura -ace. 2008 model for 3800 but i could get a good deal on it. I want a lightweight and very competitive bike that i could eventually break into road racing with. What would be a good pick?
