I have a TREK 1500 WSD ($1000) and I love it. My last roadbike...well...let's just say I got if from Santa Claus. I tried several including a Specialized (men's) and didn't really understand what people meant by "it has to fit you" until I rode this one. I'm 5'6" and I got the 51 cm. I've had it for two months and have ridden it 30 miles each time out and my neck and shoulders don't hurt at all. It's great.
