Need help identifying this Mavic Cosmic rear hub..
I picked up this wheelset last week for next to nothing, and now I'm starting to understand why. Two LBS's were stumped as to what kind of cassette this thing would take. The consensus seems to be that it's some kind of proprietary Mavic system. There's very little information online. Perhaps someone here could lend some knowledge?
All I know is that the wheelset is from around 1994, has sixteen bladed spokes, and is kind of blue.
Ideally, I'd like to use it with a Campy Chorus 8-speed drivetrain. Am I wasting my time?

Sure looks like Campy 8-sp to me. One "groove" should be slightly larger than the others, but the 8 splines should be the same size. Sort of.
Killer wheels, in my opinion, Mavic's answer to the Vento and Shamal.

Original campy 7/8 speed spline pattern was symetrical, no wide groove or spline. The later EXA-drive 8-speed pattern had a single wide spline to enforce cog alignment. Fortunately, exa-drive cogset will still fit fine on an early cassette body, just keep them aligned correctly for good shifting.
Cassettes and Cogs - Branford Bike - Seattle/Bellevue - Campagnolo Pro Shop Looks to me like you have the original campy spline pattern so any 8-speed campy cogset (exa-drive or original) should fit and work fine with 8-speed chorus drivetrain.
good thread on various mavic/campy spline patterns and bodies at; Mavic Helium Freehub Body

Thanks for your help, gents. Went ahead and ordered an 8-speed Exa Drive cassette. If that doesn't work, I'll resell these and invest in a hyper-inflated set of Shamals.
