I considered getting Kysrium Elites, because I didn't want to spend more than about $450 on wheels for training. I race on Zipps. They rule. Instead of Ksyrium Elites, I got DT 240s hubs built with DT spokes on DT R 1.1 rims. 28F 32R...etc. I think it is a great alternative to Ksyrims and you can get them from a guy who sells them on eBay...but for you I don't know...DT probably doesn't make them in 650C. I wanted some fast wheels for training, but in the end I decided to get wheels that I could ride home if I broke a spoke. A buddy just pulled a spoke through his Ksyrium SL SSCs they other day, he had to use his cell, stand around and wait for somebody to pick him up and now stands to spend $150-200 to get a new rim and a rebuild. Mavic really has you over a barrel if you have a problem...and you have no wheels for a week or two at best. Make sure you weigh those factors before you make your choice.
