Mavic Cosmic 1st gen freehub

So this happened today slowly cycling to the shops... No idea how or why, but it did...

If anyone has a 1st gen Cosmic freehub maybe on and old battered rim they don't have any use for I would gladly take it off their hands for good cash. Failing that, I guess my only option is to source a new wheel, with it being such an old and outdated design...?

... Also, what are your opinions on building a rear hub on the Cosmic 16h rim and using a Dura Ace 32h hub?

That would solve the weird freehub issue if it went wrong in the future.

building a 16 out of a 32 h hub is more complicated than it seems, as using alternate holes means the spacing between them on the L and R side of the wheel are not quite right. In turn the wheel ends up being not quite right and when you only have 16 spokes that is... you guessed it, not quite right.
If you can't sort the freehub, I would rather keep the rim for a front wheel build and get something else as a rear

gipiemme and Campagnolo did 16h hubs from that era and with more normal fittings. Possible to swap them for the mavic hub?

Cheers for the replies. Yeah, I did a bit of digging and realised the 16 on 32 wasn't the best solution... I think I'm gonna pick up a Mavic 571 hub and swap the freewheel out onto the Cosmic hub. Seems like the simplest fix and leaves me with a nice spare hub I may build up at a later date.

Not exactly easy to find... are the freehubs compatible?

There's a few about I've got my eye on at the moment. They look like the same design, just the Cosmic hubs are 16h and not badged up as 571.
