Mavic Ksyrium SL Tubular Cyclocross Wheelset MXP

Up for sale is my cyclocross race only wheelset. These wheels have been awesome but alas I have moved onto disc brakes so they have to go . I originally purchased them with 150 road miles on them in mint shape. I believe they are 2010? Mavic Ksyrium SL TUBULAR. Campagnolo 9/10/11 speed freehub body. No cassette. No skewers. Clement MXP's glued and taped on Belgian style. Sealant has been added. 1.5 seasons on these tires. Still in great shape. They are straight and true. I am asking $500.00 plus shipping. Thanks!
