Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Quick, I need some help - ghetto cog removal

ok, if anyone's on at this time of night...

basicly you can assume I dont have any tools (actually I've alot, just not a cog removal tool). What's your advice for removing a super stuck cog? I've removed the lockring and the thing's not budging - I've been riding it around trying to lock in a skid vicious enough to remove it but to no avail.

Anyone have some tips?

Sweet. Rotafix works better to get the cog off than on (actually it probably works just as well to get that sucker on).

yeah, i was going to say reverse-rotafix it, but i was also going to say CHEATER BAR, which is just about my favorite tool, ever.

put a chainwhip on that muther, and stick a long pipe over the handle of the chainwhip. you've just given yourself a bajillion more foot-pounds of torque.

torque is the shiznit!!!!!

vise works suprisingly well just throw it in cog side down and spin the cog off with the tire as your handle

wrap a small piece of chain around the teeth before you vice it and it hurts even less

it hurts my heart to hear you express torque in foot-pounds.
