I'm about to pull the trigger on a caad9-4 which comes with shimano rs10 wheels. As I understand it these are pretty low end wheels. It's my first road bike and I expect to go ahead and ride these for a while but suspect I'll upgrade around summer time. I don't really have any money for the bike much less an expensive set of wheels, however, I'm curious what is out there that I can start to save for. I'm 200 lbs (down from 220 already) and expect/hope to lose another 10 or so if I keep riding so I'll still need a somewhat robust wheel. I have no interest in fancy carbon wheels. Just a decent, fairly light, wheel set. Any suggestions? Also, are the RS10s really all that bad? Thanks.
