    When I pinged a spoke on Friday I didn't think it would be a particularly big deal. I knew I had spares in a range of lengths; even seeing that it was driveside didn't seem like it would be particularly troublesome as I currently know the whereabouts of both my cassette lockring removers. However, upon eventually managing to waggle free the seven other sprockets it became apparent why the largest one had not wanted to come off and why the thin metal rod which was supposed to keep the sprockets together had snapped near the inside end. The broken spoke was leading/outside-flange, so there's no way a fresh one can be fitted with the sprocket still in place; whilst I can live with one too few spokes for a wee while I'd been hoping to keep this drivetrain going until the spring (though the replacement was recently bought when I saw one going cheap), so does anyone have any suggestions (other than attempting to hold the sprocket still with one chainwhip whilst using another sprocket and another chainwhip to try and rotate the freehub body, which didn't work) for getting this sprocket off? The hub is a cheap piece of crap which came with the cheapest rear wheel the BikeWorks had when I needed a quick replacement last year so can be sacrificed if need be and I have a new rebuilt rear wheel ready to step in which has a much less cheesey-soft freehub shell.

    Take the freehub body off the wheel. Hold the freehub body in a vice and remove sprocket with a combination of penetrating oil/chainwhip/hammer/violence.

    You could take it to a shop to see if they can fix it. Otherwise, if you can't get the sprocket or freehub body off, just bin the hub. Maybe keep the rim if it's still got life in it. A replacement hub and spokes can be had for not that much, likewise 8 speed (?) sprocket clusters.

    Freehub comes off pretty easily.
    You need to take the axle out, put an 11mm allen key into a workbench, slot the octagonal hole in the freehub onto the allen key, turn wheel anti clock wise with a fair degree of force. After a bit of creaking and swearing the freehub comes away and can be replaced for about £15, you might as well repack the hub with fresh balls whilst you've got it in parts.
