Does anyone know how to adjust the freehub body on a Mavic Cosmos rear
wheel? After taking the axle out, there is no flats for an allen
wrench (like Shimano). The freehub body has developed some side to
side play that is effecting shifting in the 12-15 gears.

TIA,

jtm

Cannot adjust or remove the thing. It is an offshore, lowend, permanently
attached to the hub body. Which means that unless you can overhaul a freewheel,
then you cannot overhaul this one.

Not uncommon with the few I have seen.

Peter,

Unless the Aussie market gets a different Mavic Cosmos rear wheel then I
have performed this maintenance.

I have just completed an overhaul of the Cosmos hub. It had developed about
2mm of larteral movement at the wheel which was frightening at speeds of
80kmph on descent. I removed the freehub, pulled it apart, cleaned and
repacked the 50 balls, bolted it back on to the hub fitted the sealed
bearings and adjusted the wheel without a problem. The seal arrangement is
easily reused unlike Shimano which are fiddly.

I picked up the info to do this from the www.tech-mavic.com site which does
not seem to be working these days (login "mavic-com", P/W "dealer").
Perhaps someone out there has access. However, I do have the PDF files and
they indicate that it is an easy operation.

Oh, I am not convinced as to the source of the lateral movement in my wheel
but the overhaul appears to have fixed it. I guess I will try a couple of
descents and test it out.

Second gen hub methinks..not the first edition.
