Mavic ED10 Lockring Question
 

I picked up a set of Mavic Cosmic Elites with an ED10 freehub body. The wheelset did not come with a lockring and my Campy 9s lockring (13-26 cass) does not fit. Do I need to get a Mavic lockring? If so, does anyone know the part number or where to buy?

The lockring that you have fits the old Campy hubs with 26mm threads. Since 1999, when the hubs were redesigned, the lockring threads are 27mm. Your Mavic hubs have the 27mm thread, too. There are also two diameters - one for 11T cogs and one for 12-13T first cogs.
