This is my last post on this, I don't really want to derail anymore than I have, but I think you need to consider more than just the technical aspects here. There are issues with the technical stuff, but business and user experience are just as, if not more, important when you consider adoption of new innovations (any innovation, not just gearboxes). As a user, if I have a Pinion gearbox fail or need service, that means it has to be removed from the bike and replaced. Who is doing that? How long am I going to be out of...

For what it's worth: I'd still rather have all my tech rumors in one place instead of having to subscribe to a new thread for every new rumor. The current concept of one, singular annual tech rumors thread would work beautifully well if everyone just stuck to posting actual tech news and rumors. The problem is the guys endlessly talking themselves in circles or posting e-bike content (-for which there is a separate thread) or starting completely redundant discussions (like the 78th discussion on the feasibility of gearboxes). Maybe, what this thread needs is a more hands-on approach to moderation...

Gearboxes, the “fusion energy” of MTB.

People have been saying gearboxes are the future for what, a decade now or more? I think they are really cool and innovative, but they aren't going to see widespread adoption or replacement of current drivetrains. They are heavier and less efficient, the frame also has to be built around it, which means if you don't want it for some reason, that frame is out for you. They are more complicated to maintain, shops don't have the expertise to deal with them widely across regions, and do the smaller brands like Pinion have the facility to deal with large scale...

Very few normal people do pedally rides on DH tires. Only a few vocal people on forums, certain reviewers, ex-pros, and all these folks have crazy high fitness. I guess maybe people in Phoenix where the rocks are razors and the rides are short. Bike weight matters a whole lot less than tire efficiency, especially for us humans who are bigger than average. For people I ride with, in the PNW, we're always struggling to keep up with one or two friends who seemingly float up the climbs. Pedaling efficiency still matters for bike enjoyment, a lot. E-bikes are where...

Maybe this'll be like automotive how Buick and Porsche did really well for years and now are getting completely annihilated by the more-advanced Chinese competition.

Sixfinity is the number of zeros in the price tag right?

Had to say it.

As though the the gearbox wasn't also invented in the 1800s... Feel free to hate the lightest, simplest, most serviceable, most efficient method of changing gears on a bicycle that humanity has invented so far, but the rest of us will accept derailleurs where they make sense.

Much love! I'm just stoked to be part of a brand (Vital) that I grew up being such a fan of. We might be small, but I love what we stand for and everyone out there who connects with it.

Because they consume 2+ % more of your wattage, and that only gets worse the worse your chain maintenance gets! In addition, the idler produces more noise and potentially a rougher feel when pedaling, which can create a greater than 2% change in a subjective sense. Those losses are from chain link articulation on the highly tensioned top run of the chain: https://www.pinkbike.com/news/tested-how-much-slower-are-idler-bikes-wh… If you find evidence that electronic suspension will provide 2% gains, then it could offset the idler losses, when compared to a non idler/non electronic suspension bike, but you would still be 2% behind a non idler...
