Hi Folks. I have a Orbit Eclipse Countryman bike that I am restoring. Having trouble removing the BB. It is a square drive with only one side (LHS) with a key way machined into the cup flange. I placed a C spanner in the only 1 slot and applied a moderate torque and bugga me it cracked the flange. Anyone know what type of BB it could be. It has no tool machining slots flats etc on the drive side but as stated a single C spanner slot on non drive. Cheers Kal.
