Off the top of my head, I'd say the bike is a size too small, because I am 5' 1" and I had the R600 for my first road bike in 2002. It was a 48 cm. and, I totally understand why you want a road bike.
The crappy components are what made me want to get rid of this bike after a year. Although my speed went from an average of 11-12 to an average of 14-15 after switching from a mtb with slicks, the bike never shifted right. I never could get it in the big ring. Ever.
