Solutions

This video shows you how to remove (and reinstall) a cog (standard or Carbon Belt Drive) from your Shimano Alfine 11 internally geared rear hub.  The video shows the step by step process.  The procedure requires a set of spreaders or circlip tool and a flat head screw driver.   The total elapsed time of the procedure can be between 5-10 minutes, however it should be warned that removing the circlip could take longer and be a somewhat frustrating process.
