  • In lay/non mechanic terms, can someone please explain to me what the deal with all these different modern BB standards is?

    I'm thinking about buying a Power2Max power-meter + cranks I need to ensure that the cranks and BB are compatible. Rotor3D+ appear to be the most versatile being compatible with BSA68, ITA70, Cannondale BB30, PF30, Pressfit BB86, BBright.

    One bike currently has an "FSA BB-6000 Gossamer MegaExo" BB and the other (SRAM rival?) is printed with BSA but the DS reads "33-09" and the NDS reads "38-09".

    I guess neither of these are compatible with the Rotor? Why is it all so fucking complicated??
