I say this with absolutely no sarcasm, but I marvel at minds like yours. I've watched at least a half-dozen Youtube videos (some of them twice) very closely,. I've also opened cleaned, and re-oiled my Alfine-8 hubs a few times. I've torn-down and rebuilt entire motorcycles. Yet these hubs are still black-magic to my puny non-engineering brain. I also never passed calculus. Is calculus required? Because I'm thinking calculus might be involved with the planetary gears and such in there.
