Whilst investigating a clicking, which I initially thought was my pedal, I eventually got round to my bottom bracket, a Shimano UN54. I have found that the left hand fastening, I don't know the technical term, (adjustable cup??) was actually cracked right through. Going further on the other side once I removed the chainwheel the drive side was also loose, I was able to undo it and remove the bearing without using the extractor. The cartridge itself feels perfect, smooth and no roughness or play. It was originally fitted by the local lbs, but about 9 months ago so probably a bit late to go back and expect a freebie repair.
So, can one get hold of a left hand cup without buying a complete BB assembly. I can't find anything online.
