It appears that the Shimano BB-ES51 can also be used, but I have no idea whether it is an appreciable improvement. I do know, however, it is quite a bit more expensive than the BB-ES25. Anyone else have any thoughts on this?dog.gone said:Confirmed.
68/121 Shimano BB-ES25 Bottom Bracket.
So, are we limited to this specific bottom bracket? Do we have to change cranks just to install an upgraded BB? Other options?
