Williams 58 tubulars

I am selling my Williams 58 tubulars. I have used them for only a few races and time trials. The Vittoria tubulars have never gone flat, and still have lot of life left! These are the williams with the new sixty six hubs with better engagement. I am included the williams skewers, 2 set of the williams cork brake pads and williams 11-25 cassette. I am asking $900 +shipping. Please let me know if you have questions!
