2x - 1 Derailleur
We have been thinking about adding this to the options we carry at our shop. It is an IGH wireless rear hub that has the same inernal shift range as a front derailleur. Why we have not seen this before I have no idea, but it looks intriguing. Your thoughts appreciated:

It looks like a nice implementation of an idea that we definitely have seen before. I didn't think anyone had offered anything like it for a long time but Sturmey has a current product. One of them has disc mounts https://www.sturmey-archer.com/en/pr.../cs-rf3-silver
Sachs also used to sell one. People used to obsess about chain line so they didn't like to have a lot of gears. So the combo of IGH with a few external gears made sense to them.

What existing electronic systems is is compatible with? ETap? Di2 with BT module? Seems like a nifty way to get lots of range with more gradual steps, and without so much exposed mechanicals to get buggered.

The advantage I see right away is that a lot of bikes sold now are really not intended to work with 2x. So if you want more gears that's a problem.

This is about the coolest bit of new tech that Ive seen in the last handful of years. Everything else has been 'meh' and quite bluntly most of it seems to just be stuff that is clutter and doesnt really improve a riding experience(at least mine).
I never would figure that I will switch to a 1x for gravel since gravel roads are just unpaved roads and my road bikes are 2x. This though?...I could see this being a possible change.
- The battery lasting 3 months is good and important to highlight.
- The ability to shift under load is neat, though I have never approached a 15% grade in my largest ring so is it super needed?
- $200USD for a different cassette is serious money.
- The cassettes only going up to 34t is limiting. Hopefully a 36t will be added soon.
- $2860 for their wheelsets is bonkers. That will eliminate all but the most willing of early adopters.
- The lack of standalone hub so you can just build your own wheel(or have it built) is a massive drawback.
- Service is a question- how fast will issues be resolved when something breaks or the bluetooth simply doesnt connect? You have a cyclist with a $3000 wheelset that only works in whatever gear ratio it happens to be set on.
It doesnt really do much for me that a 2x doesnt already do though, so if my view is similar to others, the cost may be a big hurdle. If this catches on and comes down to a more accessible price point, I would for sure consider it when I need to change my drivetrain.

If I ever got this - I would wait to see the long term reviews on how it holds up and the price would have to be lower.

I figured the money was too much for me. People buy pinions though, and they aren't cheap even before the special frame and they are relatively heavy.
My gravel bike is 2x. 28/42 up front. That's not really supported very well by manufacturers, if at all. I'm resigned to getting the equivalent 1x system, which means I'll go from a 28 32 to a 42 50 or something like that. It will take some getting used to looking at that
I wonder if you moved from Des Moines to Dubuque, you would feel differently about 1x. In Central Pennsylvania, all the roads either go up a mountain or down a mountain. 42-11 is a pretty big gear on gravel unless you somehow find yourself wanting to stay up with a pro peloton. I have won the sprint at the end of the local Wednesday night gravel worlds in my 42-11.

I have 48/32 with an 11-36 right now. Maybe I would change to 46/30 if I were in DBQ? Heck, if Praxis made a 46/30 when I bought my current crank, I would probably have that and an 11-34 cassette.

Yeah cost is an issue as many point out. That is a carbon wheelset though plus the cassette and IGH so maybe that helps somewhat. IGH technologi si pretty well established, but they are not as a manufacturer of it. I do wish there were a hub-only option or an aluminum wheelset. We woild be the first US dealer if we go for it.

The concept is brilliant, the execution is seamless, the cost prohibitive for most. I spend a lot of money on bikes but that is two grand I just cannot justify. I still hope they can make a go of it. Innovation is good for the cycling industry.

Frankly, if this is reliable and they get the cost down enough this could become a common 2x drive system. No wait, Shimano did not patent it so they will crush it out of the market.

I still have to watch the video, but I skimmed the posts, though it’s the title that got me intrigued...is there a way to get two gears instead of a singlespeed so you can have both a high and low gear, though without derailleurs? Would be nice on a winter bike, mainly for roads, with the two gears optimized for average speed/cadence on flat roads, plus a climbing gear.

All I have is anecdotal evidence but within my group we have about an even split of 1X and 2X riders. I'd say over the last three years the number of chain drops for the 1X users is close to 4x or 5x as many, at least. Chain stretch, pebbles, mud, washboard.. all contribute to dropped chains. And not only does 1X drop more often but you have to stop to put the chain back on.

Hmm, fortunately I don't have that problem. Maybe someday I will, but 3 years going, I've dropped a chain exactly once, and it was totally random. Though I run chain rings designed for 1x use and clutched RDs.

So do all of us. It's actually getting to the point that if the group is big enough and the ride long enough, there is almost a 100% chance someone will drop their chain.

The one I had as a kid was Bendix. Two red stripes on the hub. A bunch of bikes of my friends had them back in the 60s.

That was it! Must have been a Bendix then. I was too poor to have one back then so I was on a single speed. Who knew I was a cool single speeder before it was so fashionable!
