I have inherited a lovely old racing bike but the bottom bracket's fixed cup seems to have warped or (more likely) been forced in cross-threaded, so it does not sit flush on the rim of the frame. I couldn't budge it with a standard spanner so even tried a Stilson wrench with a length of scaffolding bar for extra leverage, but felt I was going to damage the frame before it would move.
I'm 90% sure its a left-hand thread, but its an Austrian frame and I read somewhere that SOME continental frames have both cups RH threaded.
Any advice? If I do shift it, would any bike shop be able to Re-thread the frame (if it needed it) so I could fit a sealed bottom bracket unit?
