I am looking to replace a rear road rim. I am not racing (don't need top of the line) and have a few rear hubs (24h & 32h) to choose from. I have found a few good web sites for spokes but I have not had as much luck with rims. Does anyone have a favorite catalogue or web site for purchasing road rims? I am fresh out of grad school so cost is a factor. Thanks for the help.
