    Cassette jammed on freehub

    I have a Niner S.I.R.9 with a WTB laserdisc lite rear hub. I have managed to dig the splines of the SRAM cassette in to the splines of the hub. Does anyone have any suggestions on removing it? It'd be nice if I could salvage these parts.

    Worse case, I start saving for a set of wheels for the Niner, I guess they could use an upgrade anyway.

    Do you have any way to hold the freehub body still while turning the cassette backwards with a chainwhip? That could possibly undig the splines from the body and allow you to pull it off. You may be able to get a visegrips on the part of the freehub that sticks out past the cassette.

    I've found a small screwdriver wedged between the teeth of the cogs can be used to carefully pry them back counterclockwise one at a time.

    You'll also want a metal file to smooth out the splines on the freewheel which will be a little messed up where the cogs dug in.

    This is a very common problem with light alloy cassette carriers, I've always been able to salvage things by working carefully.

    I had this problem with new light wheel with soft alloy (light) freehub.

    Undo lockring in normal fashion,
    remove cogs to extent possible ie until you get to jammed cog
    Using 2 chain whips, one applied normally on the cog with most teeth eg 23-27
    put 2nd chainwhip on the cog that has dug into the freewheel
    it usually budges, some gentle tapping with small peen hammer may help

    <edit> and clean rough edges on freewheel with small file as mp says
