I think I've done a wrongun!
I was trying to remove my square-taper bottom bracket and, despite trying desperately not to, I've gone and broken most of the "teeth" off the collar with the removal tool. The bottom bracket hasn't been taken off the bike in 9 years, so it's pretty well fixed.
The teeth on the other side are still intact. Does anyone know if there's any chance of me removing the thing now?
