Mavic Cosmic Elite Wheel....Spacer needed or not?

Got some new Mavic Cosmic Elite wheels (Shimano M10). I have swapped the 105 (10spd) cassette from the old Bontrager Race wheel and there was a spacer on that hub. In the Mavic 'manual' it says to use the spacer for Shimano cassette's, which I have done. (It says spacer not required for SRAM)

On fitting/trying the the wheel and without adjusting anthing I now find I can't get into the largest sprocket, the rear derailleur is hitting the 'stop'.

Before I go adjusting things, I just want to double check whether that the Mavic spacer is really required for 10spd cassettes. The Mavic 'manual'/website is next to useless regarding infomation.

Can post some pics if needed.

Many thanks.

    I think you need mavic spacer + shimano for 10 spd on mavic wheels.

    Mavic Aksiums, Ksyriums & Cosmics have the Mavic M10 hub (unless they're Campag fit, when they have an ED10).
    This M10 hub is not a Shimano hub, it's a Mavic hub.
    It has the same spline pattern as Shimano & SRAM but it's wider than a Shimano hub because Mavic also sell a wider Campag-spaced cassette which fits it, allowing you to use it on a Campag bike.

    Thus to run Shimano or SRAM on it, you need a Mavic spacer, which is ca 3mm thick and has three notches in it (doesn't matter which way round these notches face, just fit on hub before the cassette - really old Shimano cassettes used to have three protruding rivets but no longer)

    If running Shimano 8sp or 9sp, this is all you need, but if running Shimano 10sp, you *also* need a 10sp spacer
    - a Shimano 10sp cassette is actually narrower than an 8 or 9sp cassette, so to run one on a Shimano 8/9/10sp hub you need a thinner spacer, ca 1.5mm, which comes with the cassette.
    - so if running on the Mavic M10 hub, you need the Mavic thicker spacer because you're running Shimano on the M10 hub, *plus* the thinner Shimano spacer because it's 10sp.

    Some people have said that with a SRAM 10sp cassette, you can get away with just the Mavic spacer : dunno, not tried it myself.

    Wow! Now that was what I call an answer. :D

    Thanks a lot to you both. Especially to andy-wrx for explaining it too.

    Now fitted both spacers to hub and now works like it should.

    Thanks again.

    Hi Zexel
    sorry to bring up and old topic, but how do you find the wheels agains the Bontrager Race.
    i am looking at a pair of the mavic's but not convinced there will be much diffrence to the Bontrager?

    Thanks for any help

    No Probs.

    Actually not much difference at all. I liked the Bonty Race's. The actual weight is about the same for both.

    The Mavic's are a nice strong and smooth wheel if a little on the heavier side. Nice and stiff, although I don't think I ride fast enough to gain anything from the aero of the Mavic's. Still straight and true. (I'm 88kg)

    My only gripe is that a couple of the bladed spokes on the rear have rotated slightly, no biggy really.

    But yeah, am happy with the Mavic's although if I hadn't had to change Bonty's I don't think there is much (if anything) to gain with the Mavic's.

    I have just changed the stock wheels on my Marin MTB to some "PRO-LITE Allien" and the difference was, 'Wow!'. Now thinking of getting some PRO-LITE for the road bike now as 'spare' set , just have to find a way of getting them sent to the house without the wife seeing!

    Hope that's helped.
