I've seen it argued that different chains affect drivetrain efficiency, and I understand (generally) the potential efficiency problems with cross-chaining, indexing differences, different sized cassettes, different sized chainrings, and different lubricants. But my understanding is that the only real difference between cassette 'tiers' is weight.
Do different cassettes have measurable differences on efficiency? For example: DuraAce vs 105 vs [insert random cheap brand]?
Maybe this is obvious and I'm missing something. Thank you in advance for your thoughts/insight.
