    ok, so the cassette is finally off the wheel!!!

    i wanting to put a 10spd 105 cassette on a campag vento, but it wont fit.

    the vento wheel previously had 8spd sora on it!

    i have been told it will fit, but the cassette is too "big" and i cant tighten the lockring back up!

    help!!!

    thanks

    p.s. i have tried it without a spacer behind the cassette!

    thanks!

    Sorry Steve23, In most cases it should of worked. I guess your Ventos must be so old they don't have a hyperglide freehub.

    In that case you can totally ignore what i've just put.

    haha fair enough, but it just wont fit!

    does there HAVE to be a spacer behind the cassette?

    No, the spacer is just there to pack out the space (the clue is in the name :smile:). You only need one if the cassette is too short for the hub body.
    Hmmmmm, so the 10sp cassette won't fit on account of being too long to allow the lockring to grip the hub, yes? If so, have you considered taking off the smallest sprocket and running the cassette as a 9spd?

    could do chuffy. as it only going to be used as a tempory fix!

    so just take the smallest one off and put the lockring back on as normal?

    Sorry i'm all out of ideas.

    My only thought is Mavics huibs sometimes include a 2mm spacer to make them Shimano Compatible. The spacer that normally goes behind a 10speed cassette (on non mavic freehubs) is only about 1mm (or less) thick.

    Yup. Just make sure the lockring properly engages against the cassette. You may need a spacer...:smile:

    Did you have a spacer fitted between the largest sprocket and the spokes when using an 8 spd cassette? You won't need the spacer when using 10 spd, that is why you have not got enough space for the lockring.
