I've been considering the 2009 CAAD 9 6 lately. I prefer the silver color over the black and white (with Shimano 105) options. I am on a budget and the price is good too. Is the Tiagra group that bad? The reviews here are very different and confusing. I am willing to take the weight penalty as long as the Tiagra transmission does its job. What about the Shimano R500 wheelset reliability (heavy I know)? I'm not racing but ride almost everyday 30 to 60 km. I also join pretty fast (for me anyway) club rides. I might be able to upgrade some components after 1 or 2 seasons but I don't want to curse the bike in the meanwhile. Thanks for your input.
