Managed to get the crankshaft oot and confirm the bottom bracket is ******, one bearing completely disintigrated, a few loose bearings and some metal filings floating about in there . Now have to get the BB out, see if my mate has the tool to take off the retaining nut, if not I shall dig out the monkey wrench!
It's a FSA system, trouble is knowing what tools are called; I can see what the job is and what is needed, but what is it called - all a bit long winded but a good learning curve - I used to fix my cars so surely I can fix a bike
