Hi, I've ordered a pair of Mavic wheels to replace the standard ones on my bike. I've got 2 cassettes, both Shimano 10 speed ones. They both have spacers but looking on here it seems I need an extra spacer for the Mavic hub, is this correct? If so, where on earth can I get one? I've been led to believe that this

is incorrect but this one that may be correct has a ridiculous cost for P&P

can anyone confirm that this is right, and hopefully recommend a less costly alternative to the one above?

Cheers!!

    I vaguely remember getting one included with some Mavic wheels..............but if not your LBS will have loads and probably just give it to you!

    Unfortunately you do need it, I swapped my freewheel from shimano to campagnolo and you don't need it for Campag. If you pm me your address I'll stick it in the post if you want?

    My Mavic wheels came with a spacer when I bought them.

    cheers lads, they are used wheels so I'm guessing there will be no spacer. Flexisurfer is kindly sending me one so should be sorted.

    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 so these cassettes fit it, but it's actually 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 just by fitting this cassette.

    Thus to run Shimano or SRAM on it, as it's wider than a Shimano hub, 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, or SRAM 8 or 9 or 10sp, or Tiagra 10sp, this is all you need, but if running Shimano DA, Ultegra or 105 10sp, you *also* need a 10sp spacer
    - a Shimano DA, Ultegra or 105 10sp cassette is actually narrower than an Shimano 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.
    (well, it's milled-out at the back, so this spacer fills it in and makes it same width as 8sp or 9sp : SRAM 10sp cassettes and Shimano Tiagra 10sp cassettes aren't milled-out like this and so don't need the spacer)

    So when running on the Mavic M10 hub, you'd have had the Mavic thicker spacer because you're running Shimano on the M10 hub, *plus* the thinner Shimano spacer if you're running 10sp.

    OP, the two spacers you link to at the top are the Shimano 10sp 1mm spacer, not the Mavic M10 3mm spacer.
    This is it http://www.sigmasport.co.uk/p/20414/mav ... te-spacer/
    When you buy the wheels new, they will come with the spacer - if you've bought 2nd-hand, who knows

    cheers Andy, wheels are used (only Aksiums, not got uggins of spare ££) so dunno if they will come with spacer. I've just ordered this

    http://www.evanscycles.com/products/mav ... c%20spacer

    and I have a Shimano 1mm spacer. It's an Ultegra 10 speed that's going on, I'm guessing I'll need to fit both the spacers right?

    Yep, looks correct Mavic spacer, and yep, you should need both
