how to remove bottom bracket
To remove any bottom bracket, you first need to remove the crankset. For most of our cranksets, youâll need an 8mm allen key for this job. Once youâve removed the crank bolt, take the left hand crank off and push the axle through the bottom bracket to remove the right hand side.Your FSA bottom bracket will likely be one of four types; BB30, PF30, MegaExo or MegaEvo.hese are available from all good bike shops. Fit the tool to the bottom bracket and loosen and remove the right hand side followed by the left hand side. Removing a MegaExo bottom bracket is very similar. You need the same external bottom bracket tool and you can follow the same process outlined above.
