What they both said! I completely agree. I ride a 47 cm Trek Pilot 5.0 (carbon/Ultegra) WSD road bike I love. I bought it used on ebay and got very lucky! I have changed out some of the parts and added a riser stem as I need to be more upright, but other than that, it fit me very well. If I were to buy another road bike, I'd look at Trek WSD models first. They've gotten lighter since mine was made back in 2007 and use compact double cranks instead of the triple I have.
