Forget that! Don't waste money on race wheels and training wheels. Think about it, you actually end up spending more money to ride crappier wheels most of the time. Besides, every day is race day ;-p

FWIW, my 404's have been the only wheelset I've owned the last 4 years, they've been bombproof, and they're not even the toughest wheels on the market. Carbon wheels are much more reliable these days than they used to be.
