You have to bare in mind, that all the big companies didn't manage to develop anything similar to the Speedhub. That makes it even more impressive, that Rohloff did it in around 1996 as a small company!

Mercedes vs. Lexus.

Guess I have to watch it another 5 times until I finally understand. But definitely not your fault. Great video!

mr rohloff passed away last few months ago.

20years, 35,000km so far and no problems so far, German enginering at is finest

What amazes me is the brain of the inventor. Awesome video

Layman's term please, I'm confuse

But so how does this engineering spirit first into Rohloff's newest policy about refusing to sell seals? If your hub starts to leak oil, you cannot fix it yourself, you have to sends the entire wheel back to a "Rohloff Service Centre". So how does THAT work if you are somewhere remote?? You can buy the special tool to do it: still can, lots of people still selling it. But no seals. I've just had the UK distributer refuse to sell me any seals. They say I must send the entire wheel to them. And it's no9t under warranty: is entirely at my risk if I want to do it. I really don't like that.

Nope, didnt understand any of that lol

The mind boggles and hurt

What a tiny mechanical "wonder"! I've been driving Rohloff for about 10 years and shifting with it is simply fun because it happens so quickly and intuitively. In addition, the robustness, a really great development. Thank you for the clear explanations!

Great explanation and very articulate with precise terms. It would be nice if you discussed the need to minimize input torque when shifting as excessive torque can prevent or slow a shift operation; and in some cases, it may cause the Rohloff to skip several ratios or skip to a higher ratio: for example, shifting from 7 to 8 under high torque might cause the hub to fall momentarily into 11 or 14. These issues are completely eliminated when the shift operation is timed for when the rider has their cranks in the vertical position (applies minimal/zero input torque). For single riders, it is easy to time the shift. For tandem riders, it is more difficult. Food for thought it you ever decide to add to your video or produce a separate video focusing on this aspect. Thanks.

Thank you Dan, for the in-depth and complete explanation of this Rohloff Speed ​​hub! A masterpiece of bicycle hub-level design and engineering that has proven itself fully in the field. One day hope to be able to see and visualize every acceleration step in a follow-up video. Thanks again👌👍

One universal truth. No one can understand the workings of planatery gears by listening to someone explaining it.

Very well done! Informative, professional, top-notch. This explanation helps to tame this otherwise daunting piece of machinery. Thanks Dan!

Not going to pretend I understood this but makes me appreciate my Roloff when I'm out riding!

Thank you so much for this video and the insane amount of effort you put into it, specially with all your CAD models and motion analysis. Really enjoyed it!

Thanks for taking the time and making the effort to explain this technical marvel to the internet :) At first perception, it sounds like competent techno-babble to match Star Trek - but this is for real. Amazing.

So precise, beyond what i retain, however, thank you! Bike lifers such as myself will appreciate this info! Best regards. Really awesome

Holy mackerel. Who ever thought bikes would get this sophisticated.
