    It's always exciting to see new ideas like this. Not entirely sure that this will change anything, but it's still a really cool idea!
    I lost my phone number. Can I have yours?

    From Ceramic Speed; It should be cheap because you won't need $1,000 jockey wheels. https://www.ceramicspeed.com/en/spor...-for-sram-11s/

    Or not.

    I'm not afraid of unusual designs (I have a Scalpel and a Grail). My biggest fear with this new drivetrain is the arguments that will follow... it will make us miss the simplicity of the "Rim vs Disc Brakes" debate ;-)

    We NEED to get away from chain driven systems (especially in Mt. Biking), I give these guys credit for making baby steps in that direction. I don't actually think this iteration will fly, but hey...they are trying.

    Catch being-nothing is as reliable/efficient and cheap and easy to replace (ubiquitous) as 1/2" pitch steel chain and chainwheels.

    Agreed. I actually think it's great that they're trying new things. That's the only way innovation happens.

    Doesn't exist? You haven't seen endless (rivals disc vs rim brake threads) posts about the chain lube and cleaning methods?

    Cars have been using this forever. Motorcycles have been using this for almost forever.
    My guess is that the power loss from changing direction of spin will be too much to be useful in races.

    True, and shaft-driven bicycles are more than a hundred years old too. The roller bearing drivetrain is interesting but still in early development and I hope they make something really useful from it.

    It does spur an idea though, Every year I crush tomatoes for sauce in a grinder, I could attach the trainer to the grinder and turn it that way, killing two birds: getting good spinning done instead of turning that friggin' crank; and getting sauce made. Everybody wins.

    The major design flaw in the revolutionary drive train is the cassette.

    Like the rotors on disk breaks (meat slicers!), this cassette will similarly saw off riders' limbs and appendages in a crash.

    No thanks, Mister Inventor.

    Not only that....they're still using a highly-dished rear wheel when there is no longer any reason to.

    I'm sure it does but most of it is covered from sight so it will be perceived like hub bearings.

    All the better to forcefully launch the Spinning Teeth of Doom into an innocent bystander when the wheel potato-chips.

    1) those little bearings aren't sealed. They ain't gonna last long, especially if they're ceramic.
    2) those little bearings look like they're ~6mm. A 6mm bearing only has about 150lbs of static load capacity. I can't imagine they'll be strong enough to last very long.

    I'm sure someone can market a speed loader for easy replacement.
