I love that you think gearboxes will become ubiquitous on ebikes and will entirely replace mechanical derailleurs and electronic battery-powered derailleurs and electronic hard-wired derailleurs and autoshift derailleurs and internally geared hubs, instead of becoming one more option among a confusing sea of options and pricepoints, like everything else in the bike industry. If only it were that simple.

Trek should have put an embargo on their supply chain relying on forced labor and debt bondage 🙄 Just post the bikes

Can we please not turn this into a d*ck-measuring contest regarding who rides which steep thing w/ which gearing?

WONT SOMEONE THINK OF THE BRAAAAAAANDS! THE POOR BRANDS!

So who's going to post the two Trek 32" bikes from the B2B site?

I would just like to call out the fact that 100% of the 6 mens elite world cups so far have been won on 148 rear ends.

I did not expect an XL Yeti to come with 465mm chainstays in the short setting.

What if we tried putting a small derailleur on the front cogs, may be just like 2-3 gears, then a 5-7 speed cassette on the rear with another smaller derailleur? Same ratios but better weight distribution?

Not a bad point. I suppose that's why all these racers on gear boxes are doing so well

Taken from PB, new TRP brakes in the works (or at least calipers)

DHF sucks. Always wash out unless you really commit to the lean and never ride berms

Dudes in their mid 30s will shit on Lycra then go out wearing skinny jeans. Brother the call is coming from inside the house!

All this drivetrain efficiency/Gearbox discussion is making me think about the joy I get from riding my singlespeed.

Two words in the title of this thread make everything relevant and on-topic. Tech and innovation. If there was strictly a “tech rumors” thread, it would inevitably discuss the technology that a product is competing against or replacing. There’s really no way around it. If you aren’t going to discuss the relevance of a new product or innovation, then what’s the point? As far as Ebike derailments go, the separate thread is nice. But you have to argue that 90% of the tech and innovation in MTB right now is because of Ebike market dynamics.

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...

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...

@dwhere you're better off starting new threads for new topics. tech rumors and long-form threads aren't very efficient these days

I don't think most people articulate why they dismiss gearboxes very well, or at all haha. For me, I'm not too interested in them for a couple of reasons. Firstly, I don't have the issues with derailleurs that others seem to have, I don't smash them or snag them on rocks, and I race DH and enduro in Utah and Colorado so there are plenty of opportunities for me to do so. Secondly, I like mechanical drivetrains and don't like grip shifts. Unless I have missed something, all mechanical Gear boxes have to use a grip shift to pull cables...

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.
