Mavic Ksyrium Wheelset for sale. These wheels have new Enduro bearings installed. The rear rim was replaced with a Mavic Ksyrium ES rim. The rear wheel spokes were all replaced. The free-hub was also replaced. The wheels are perfectly true. They have Continental 4000tires with Zipp tubes. The rear quick release lever is Dura-Ace and the front one is Mavic. I was using these wheels with a ten speed cassette. You can also use them for 9 speed. These wheels can be a huge upgrade for your bike. Let me know if you have any questions.
