If you have one, use an old chain nailed to a piece of wood.

here's another way, if you jsut have the wheel and no frame or you can't be bothered rotafixing it,
get a really big screwdriver and hammer ..(lockring-style).
it works!

fandango If you have one, use an old chain nailed to a piece of wood.
Have you ever done that? I wouold not think it would work unless the cog was loose ish to start with, but I may be wrong anyone tried this.

Actually the vice method works well. Wrap the cog in an old piece of chain and clamp it between some wooden blocks. Then just 'steer the bus' the right way and volia, hey presto!
This is what most LBS's do (other common technique is a cheater bar over a chainwhip) to free stuborn cogs.
Just make sure you steer the right way, otherwise you'll never get the cog off :)

My LBS guy actually uses his teeth to free stubborn cogs. All the real bike mechs were trained in this technique.. the noobs today just don't have the skillz..

yeah that I can see would work but is very diffrent to nailing a chain to a peice of wood.

Cool stuff, thanks guys. I may try the rotofix thing sometime but I reckon the vice may still be easiest method.

If you have a vice.
I've got loads.. just not the right kind..

Vice works, but make sure you wrap sprocket in old chain....you have to tighten the vice quite tight and if you don't do that some of those cheapo sprockets teeth will just bend under the force of the vice....I know I've done it1

Vice worked well, I've kinda chewed up the nice plastic Record jaw covers though :( needed to be tighter than I expected. Surly clone 3/32 sprocket, seems pretty tough.

rotafix is the easiest. i use it for getting the cog on and off all the time, even on the road. just make sure you put some rag or an old sock round the bottom bracket shell so as not to scratch yer paint. you also don't have to worry about damaging the sprocket as well.

i don't own a chain whip by the way, as i see it as a waste of money :)

Get an old drive-side crank arm with a small ring (22t or something) on it, get 30cm of old chain. Wrap chain around crank and chainring so it won't come off, real messy. Then do the same on the cog. Then you kinda use the arms of the crank to rest on the inner side of the cog and just push down therefore loosening the cog. It sounds like it won't work, but it will, I do this all the time.
Don't do this with an expensive hub though, just incase the crank arm slips and, I dunno, combusts.

chain whip here, got a lockring thing on the end so easy peasy!

stamp on the pedals backwards!!
I want to swap the rear sprocket on my bike, I have removed the lockring easy enough, but cannot shift the sprocket, I was hoping I could just jump on the pedals to unscrew it but no such luck, its a 16t and I'm lacking in any proper tools, any advice.
The best I can come up with is put the sprocket in the vice here at work and rotate the wheel by hand to unscrew (large pipe wrench/stilsons would be my chosen weapon but mine has been nicked), but any other ideas (short of buying a chain whip)?
thanks
