My hub gear bike had an aluminium eccentric block which rotates to adjust chain tension. The square taper cartridge bottom bracket is screwed into the block.
I need to replace the BB which is over 12 years old and probably siezed in place.
I can't wrench it out in situ, the eccentric will just rotate.
Any ideas?
