Removing A Fixed Cog

[MikeCottTrials]

How do you do it? bit of a noob question i know but it has to be done

btw Ive already done a search and it didnt really help

Clamp it in a vice as hard as you can, then put a piece of scaffold pole on the crank to undo it. If you don't want to damage the sprocket then put a piece of old chain around it before putting in the vice.

or get 2 x blocks of wood and put them in between the sprocket and the vice, grab hold of the wheel and turn, job done (if you are talking about a rear sprocket)

if not above will work

Two blocks of wood idea didn't work for me, the cog kept chewing through any wood I tried.

I used an old chain, and long pole.

Just a quick question, is the chain method used to take it off a crank aswell, i have an Echo crank and bashring with fixed cog and i want to take them both off.

I wanted to get the same gearing as on my onza so would i be able to take my ordinary T-Bird cog off and put it onto my echo cranks?

Cheers in advance, Rorz!

yeah , thats what hes talking about. Its just that someone then started talking about wheels for no reason, i got halfords to get mine off and it only cost me £5.00

Is that the same idea to get a screw on bash ring off..... i have tensile cranks with a duel bash.

tryed to get it off with a whain whip, but the whip snapped!!

vice idea sound good.
