My current bike is a "regular" Trek 2100. The first season I rode it everything felt fine. Last year I rode double the miles of the year before and started having alot of neck and shoulder pain by the end of the summer.

I took a Trek Madone for an eighty mile test ride one of the days that I did a week long tour last summer. Great bike, but didn't feel a big enough comfort difference to think much about changing. In the fall I attended a WSD demo day at my LBS. I tried a WSD Madone, after having a quick fitting on it. It was a cold and rainy ride but I was so in love with that bike. They were starting to get worried about me because I didn't come back for almost an hour. My upper body felt much more comfortable.

I'm 5"4". 30" Inseam. Not sure about arm length.
