I'm new to racing and I need to get an extra wheelset. I'm currently on a Bontrager Select wheelset with Race Lite 700x23's and an Ultegra 12/25 10-speed cassette. I don't want to spend a fortune on a new wheelset so I'm thinking a new Bontrager Race wheelset with an 11/23 cassette. My reasoning is that I would have a slightly better wheelset with a faster cassette for racing. I would take the Select's to put in the support truck. I could also continue to train with the Select's. Should I run into a course that needs lower gearing I run the Select's and put the Race's in the truck. My budget is about $400 for new wheelset, cassette, and tires. What are the flaws in this plan? Are there better options/suggestions?
