The chain was not what broke when we tried that, and we did have a cheater bar. The actual metal piece that the chain connects to snapped. The crobar and firecraker sounds fun though. I'll wait until after I can try the tool in the vice though. Then it's time to have some fun with the POS

for the sake of this thread, do not quit until you get it off.

try this:
beefy chain, old chainring, rubber mallot.
put the drivetrain together.
bang the crankarm (with the mallot) in the reverse direction until it's off.
you'll want it on the floor for this one; your buddy holds the bike (brakes engaged if you have them), you wack the crankarm with the mallot. not sure what this method will do to the bb/cranks, but at least the cog won't win.

ed: even better, get a foot and a half of cheater bar around the crankarm before hitting it. make sure it's a heavy pipe. that'll learn it.

That's basically what I did except jumped on the pedals trying to backpedal them without a lockring on, or when I tried skidding it without one.

the mallot might be abrupt enough to do it?

idunno.

are you video documenting this?
because you should be.

Wish I had a video camera, only an SLR camera with no video :( . You would think jumping on it would have more of an effect (affect?).

i wouldn't, but i'm also not a physicist.
the only reason i believe that is i've taken stuff off with a mallot that no ammount of anything has been able to remove. You can slam something pretty hard fifteen times with a mallot, wheras i'm willing to bet you're not jumping on something fifteen times with as consistent a level of force.

Dude... it'll come off. You just gotta do it.

When I first built my fix. I didn't put any anti-seize on the threads for my cog. I just went to the bike shop (most of my buddies/teammates work there) and rode it around the shop stomp skidding everywhere. Like 40 mins later... I busted my kids on the top tube when the sucker broke loose.

Everyone is standing around laughing hysterically at me trying to celebrate and not throwup at the same time. Delicious experience. It will make you a man. Get it off.

On a side note... Im sure I simply missed it, but what kind of wheel is it?




Edit: The blocks of wood into a vice while you turn the wheel is a good method too. Alternate between riding and vicing.

There is actually a tool they make for this that we have at another shop of ours that I'm waiting for. Should be here tuesday. I'm not going to be doing any more skidding as I broke my wrist yesterday and have major road rash already from a crit down in san diego and I don't want to risk crashing again. Back to the tools.

I'll give you that. Just wanted to comment :o

good luck with this. I think penetrating oil is key here.

Regular ice + salt will get you below zero, but not by much. -10 or -20, perhaps?

If you want cryo-cold on the cheap and easy, go with a bath of dry ice plus ethanol or acetone. That will get you down to about -80°C. Any lower and you're starting to look at liquefied gases.

try turning it in the opposite direction

Well I finally got it off. Soaked it in WD40 and let it sit overnight then put it in the vice again and after breaking a few teeth on the cog it finally came off. I greased the threads this time.

everyone loves a happy ending!
