Rear hub uses one 6901 and one 608 bearing.
Front hub uses two 6901 bearings.
This can be found at the tech-mavic.com website, and the Mavic reps should know that

The FTS-L freehub uses a nylon bushing and a ball bearing (I thought it was a 608 but I might be wrong). But I would recommend to get a "Mavic crossmax freehub bushing" on ebay from seller "jbosboom" to get a new nylon bushing and ball bearing for the freehub (not affiliated with the guy but he just sells the best/most complete package for the price)
