Hello! I'm new to this forum and pretty new to road biking...but am hoping to get some advice. Last year I did an olympic triathlon- borrowing my friend's 51" specialized dolce. I've been looking to get my own road bike...and just came across a 2005 52" Specialized Roubaix for sale for $700. I think the fit would be good since the 51" dolce was a little small for me- and 54" seems a little large. Any women have the roubaix? Thoughts on this bike? Thanks!
