We got those on sale years ago. Mavic had come out with some new wheel, and the OPs had sat around the shop for a couple years. I just looked and it says CD which I guess is not the ceramic. Whatever it is, a season at most.
The Ceramic is what, about 50% more for the rim? Look at what you can get a whole wheel for from a company like Colorado Cyclist that makes a ton of them.
No CD or Ceramic, but basically the same wheel and cheap.
