Finding the right bottom bracket crankset combo I need to change my bottom bracket and crankset. But I'm not sure what to buy.
I know it's an eccentric botton bracket and I still need one because I use the internal gear hub Shimano Alfine.
My preferred crankset is the Shimano Alfine FC-S501.
What do I need to buy additional to the crankset? Can you suggest an eccentric bottom bracket?
Or would you suggest a different crankset?
Your bottom bracket is screwed into the eccentric. You'll be replacing the bottom bracket. The fact that it's in an eccentric doesn't affect the part choice. The eccentric is more like part of the frame.
To install FC-S501 you need any Shimano road Hollowtech 2 BB, as indicated by BB-SM4600 being the model called out in the Shimano exploded view diagram for it.
