I have just swapped the Shimano freehub on my Ksyrium SSC rear wheel (FTS-L hub) to the Campy ED10 freehub body so I can use them on a Campy 10spd bike. I notice that Mavic provides a lockring for the cogs when the wheels are bought new. This lock ring was not provided, all I received was the freehub body. Can I use the Campy 11T lockring?

Yes. I even prefer it to the soft Mavic aluminum one. It doesn't have a shim like Shimano and gets chewed up pretty fast.

if your first cog is an 11..

I assume you are using an 11T first cog, if not, you need the 12-13T lockring.
