I forgot to say two other specs:
Brakes: the Cannondale bike has FSA SL-K cantis on it and I stop just fine and can feather onto someone's wheel in a cross race. Not sure I can work in peleton with them, but we'll see. But a world of difference from my old Jake's death-brakes.
Stem: the bike came with a 120mm stem on it -way too long for me. It was semi-carbon but the LBS through on the stock Cannondale 100mm stem and it was a) lighter and b) works great.
