I'm looking to buy an Octalink BB, I need a 73x113mm. I'm confused by the different Octalink models that Shimano offers, specifically BB-ES25, BB-ES30, and BB-ES71. These different models all come in the size I need, what is the difference among all these? I've searched a bunch but can't figure it out.
I'm guessing the variation is in weight and quality with 71s being the "best"? Does anyone know for sure? Thanks in advance for the help!
