AFter about 4hrs of searching and countless bottles of Aspirin... I came across these numbers.

Mavic Cosmos 2004 Front wheel 6001 x 2
Mavic Cosmos 2004 Rear wheel 6001 x 1 and 608 x 2

Am I on the right track and now I just need to find a good place for ceramic bearings?

Also, do I need the puller to change these out? If that's the case I'll just get the bearings and take them
to my LBS. Don't feel like buying more tools.
