I was removing the bottom bracket (again) to try to figure out what my creak was and I stripped the teeth on the drive side cup. I was putting a lot of pressure on and the bike moved and now the cup teeth are about a third, if not less, of what they were before. I'm not sure if I should try to remove it again and risk totally stripping the teeth or maybe glue the bottom bracket cup to the bottom bracket remover or some other piece of metal and then do it. The good part is that I just realized that this same cup is cracked and that it's very likely been my creaking problem. If I do totally strip it what would I do? Is it possible to get only a drive-side cup?

You didn't say what kind of bottom bracket you have.

If it's a Shimano cartridge BB, my first move would be to line up a genuine Shimano bottom bracket tool. The Shimano tool sits much closer to the BB and is much easier than a Park tool to keep lined up while you torque on it. Don't forget, the right side has a lefthand thread.

Shimano cartridge bottom brackets basically come out the right side in one piece (except for the stabilizing sleeve), so you're going to have to replace the whole thing.

Good luck.

side cup you must turn it clockwise! At least that is the case for most.

1500 miles in so far this season. However, most were done on the local roads of Staten Island, NY. Picture Paris- Roubaix with Burger Kings and strip malls along the way ;o)

If it's 3-piece - knock out the rest of the bb and cut thru the cup with a hacksaw - you'll hear soon enough if you touch the frame - make 2 or 3 cuts right thru the cup and it'll remove easily. You can even go to your LBS and use their thread-cleaning tap to clean any burrs.
thats kind of extremeishmael

I was hopeing someone could tell me a good glue i could attach something I could torque it off with. I know it goes clockwise
the solutionishmael

I give credit to Jeremy at Bike line for the solution- put bottom bracket back on use a quick release treaded through the axle (campy record)to clamp the tool close against the cup, then crank away. Two other mechanics said to cut it out, Jeremy strongly recommended against doing that. There are so many clown mechanics out there, and a lot of them work at the fancy stores.
