That BB looks like the exact opposite of what i imagined-- it appears as if the adjustable cup had been glued/corroded in place and the fixed is clean as a whistle!
Weird.
How'd you remove it?
I bought it off ebay for about 24$. I was expecting it to be in better condition. Sometimes you just learn your lessen and wind up with something sub-par. The clean side looked just like the dirty side. It got clean thanks to the procedure I'm talking about in this thread. I believe the former owner must have removed the drive side (fixed cup) then just threaded out the whole bottom bracket out of the other side, so, yes, it appears to be the opposite of the normal convention.
