Well not paid yet but I'm getting 'em (with ceramic bearings for the hell of it):
I figure riding is usually #3 on the list of things I do each week (sleep, work, ride, etc) so why the hell not. My wife asked me "why" and I explained that they wouldn't really make me any faster or competitive but they would make me hang on that last little bit more when the shit hits the fan in the race. Her very knowing response: "ohhhh so it's for our marriage" (i.e. happy Chris = good husband)
