I have had 2 WSD bikes. I am 5 ft. 1" (barely). The first road bike I had was a Cannondale R500 47 cm. The levers still felt too far away and the shifting was never smooth, evn though my husband and son constantly worked on it. I now have a Trek 5200 and it is perfect. I am not sure why a lot of people get freaked out with the 650 tires. I have had no issues. My husband had a flat the other day and had a tube with a stem that was too short for his wheel. He used one of my 650 tubes (don't know how he got it in) and we continued to ride for another 30 miles.
