I already know the answer but i figure i would ask anyway. Colorado Cyclist has a sale on Mavic Ksyrium ES wheels that would be only a few dollars more than a custom set I am looking at. Has anyone ever ridden the ES wheels? The customs i am looking at are CXP33 with chris king classic hubs. I figure I will call them this week and get their opinion, but its always good to get the opinion from someone who is not going to profit from my decision.
