FSA BB-1000/BB-4000 MegaExo Alternative
My '11 Cannondale Synapse Tiagra is fitted with an FSA BB-4000 MegaExo bottom bracket and it needs replacing. Bearing in mind that FSA BBs are very expensive and not that highly regarded I was wondering if there were any alternatives out there? The sizing is quite odd, whilst it sits on a conventional 68mm BB shell the bore is 19mm as opposed to the more common 24mm and 30mm employed by Shimano and BB30. Any ideas out there?
