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.

1860s technology = a horse ? 🫣

Great thread idea; I can't wait to see how it develops. I'm going to throw a wrench into it right away though, and say I DON'T care that much about geometry. Here are my thoughts: I come from a motocross background. For all the years I've been doing it, there has only ever been one size of MX bike, and every rider had to adjust to that size. Same with geo: it's different from brand to brand, but there are no flip chips or mullet options (well, they are all technically mullets - let's call it a "same-size wheel option.")...

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...

I typically use the climb switch once per ride. I like to turn it on halfway up the climb when I remember I have it and might as well use it. I tend to turn it off halfway down the descent when I’m puzzling over why my suspension isn’t working. I suspect I am not in the minority.

No ageism in here! I'm 40, and the bike I ride most is my Singlespeed. So I, in fact, do stand while climbing, a lot.

I also read 52 books last year! Well, I didn't exactly read each book all the way through. But I read the title on the spine, and if it sounded promising, I looked at the pictures on the cover and read the rest of the book jacket.

For years people have been asking for MGUs from SRAM and Shimano and there has long been speculation that those brands didn’t get involved because they didn’t want to undermine their own market share of expensive, high wear components. In doing so they’ve left their flank wide open for a Chinese company to swallow up the drivetrain market while solving issues riders have complained about for decades. Horrific miscalculation from the drivetrain cartel.

Blame Warner is a really bad take on this, Pon is shutting their factory down and cutting 120 jobs, Warner have nothing to do with this.

i block influencers can't take it

This is a Toyota style CVT, not a belt driven snow machine type

Agreed that this motor/CVT is predictable, inevitable, and nonetheless a really BFD for the ebike market and makers of traditional derailleur-driven drivetrains. I know I'm going to sound like a broken record here, but high performance eMTB sales represent a very small market, whereas the real effects of this are going to be seen in the touring/commuter/pavement pounder market. I'd wager Shimano and SRAM sells 100 times more derailleurs/shifters/cassettes to the touring/commuter/pavement pounder ebike market vs. what they sell for high end eMTBs.

MGU = motorgearboxunit meaning electric motor and gearbox in one housing without the need for a derailleur and a big cassette. Regenerative braking would be a cool feature but I don't see that in the near future due to the necessity to transport energy over the chain/belt the other way around than normal. And I think the effect wouldn't be that big either as you can only replace the braking of the back wheel and most braking should be done in the front.

Nah, you'd be massaging an extra 2 pistons at the end of the day.

New rumor. Canyon has a press release (which was revised afterwards removing MG) that at eurobike they'll have a long travel mtb with a prototype Avinox labled 'MG'. Might be a gearbox motor combo.

they should use actual moto parts... because they are fucking eMotos. I hate those fucking bikes.

Only a matter of time before some utter moron at one of the drier race venues sets fire to the forest with one of those flares.
