I've watched the video, and I can see now how the mechanism works. The idea strikes me as a fun engineering exercise, but I'm not convinced of any long-term use case to make the approach viable. Fun concept though, and would be fun to see in person someday. Who knows, maybe some of the ideas will prove useful in some way in the future.

Hydraulic sounds interesting to me in a very specific application: tandems. I am having trouble keeping the rear shifting spot on for as long as on my single bike (all cable operated) and it seems I'm not alone with that given recent threads in the tandem forum on this. But it would only make sense if hydraulic is/was much cheaper than Di2/etap... (and 1x13 isn't quite a mainstream tandem configuration...)

Yea, i like the hydraulic idea. I just dont even see the need for ten speeds let alone 13. Unless the accuracy of hydraulic can bring it into benefit (cos cable arguably has its limits over nine!)

Would love to see a video of it. Looks like a way out of the box concept. Interesting!

A solution to a problem or a question that was never asked. Just something new that the mfg have brought out to make you think what you have is old fashioned. With a double in front with 12 speeds, you have 24. Yet back up to about 1985 even racers thot that 10 speeds were good enough.
Will mfg keep bringing out one more speed every couple of years till the rear dropout is a foot wide? Gee------------------I only have a 24 sprocket rear cluster and now they just came out with a 25. I better see my loan officer at the bank!!!!!!!!!!!!!!!!!!!!!

I watched another video on this. Two things are pretty suspicious here--neither the prototype bike nor the mock up of the drive-shaft/spindle can actually shift, which makes it seem very likely they haven't really worked that out. They also refer in the video into an actually rideable prototype bike that they've been ride-testing on a track, yet there's no video of that included in the video I watched (or any other as far as I can find), which makes me think that something major is not working.
I'm thinking this may very well be vaporware.
