I am thinking about getting a crank based power meter (either Power2max or Quarq Riken).
Now I am trying to understand what other things need to be changed on my bike and I assume it will be the bottom bracket.
My current frame has a SM-BB91-41B bottom bracket and I am having Shimano Ultegra 6700 Cranks.
Questions:
- I assume BB91 is Shimano specific and I can only fit Shimano Cranks on it, right?
- Which other Bottom Brackets can be fit onto my frame?
