Now this isn't a new concept exactly, Shaft-Driven bicycles have been experimented with since the bicycle was invented.

Crucially though, they were all singlespeed up until very recently with advanced gearboxes, and even then, they never took hold. They're more expensive to manufacture, it's all propietary stuff so good luck servicing it and the efficiency losses are way, way above what even a dirty chain gets you.

Enter ceramicspeed re-inventing the wheel, basically. Admittedly, their target audience cares little about propietary or price, so they got that down. So they invented the shaft driven cassette drivetrain.

Now, you might look at this and think: "Well, what if we introduce literally any dirt to that thing" and the answer is don't think about it.

      I'm sold, how do I most efficiently transfer the equivalent of $8000 to denmark so they sell me a drivetrain that don't work

    Doesn't honda have some proprietary gearbox that's actually kinda good? It's like more efficient and reliable because it's all in a box but too expensive to market so they just sit on the patents.

    Surprised that they didn't design a simple cover to keep those gears clean. Just throw a ceramic disc over them, leave a hole for the shaft and a second hole for the axle and put a gasket on them to keep dirt from getting inside.

      Even a plastic or rubber shroud, something anything :screm-a: aaaaa

      Maybe the one in the picture is just for demo purposes

        Yeah, I looked it up and the production model is shrouded. This is just to show off their ridiculous drivetrain

    Is there any benefit to that design or does it just look cool?

      to a prop shaft in general? It's pretty bullet proof

      To this one? It might make a bunch of dudes from denmark very, very rich off of the disposable income of dentists

      You don't have to worry about the chain slipping. You just have to worry about a bunch of other things, instead.

    Thinking about dirt in your cassette drivetrain is poor shit. I never ride my bicycle anywhere near the outdoors.

        You wouldn't. It's just for shifting, which helps you go uphill in a totally sterile environment

          show me the indoor race that includes bicycles with shifting and we'll have finally found the target audience for this

    Have you considered though: your leg hair can’t get caught in the chain, 100%, while on normal bike it’s like 99.999%
