That honestly looks like an updated version of the last Radical before original Sunn went bust...

The Kern had the same general layout around 2010.

"See You Monday" on Finn's (& Loic's?) tyres this weekend - do we believe Finn saying its just a way of saying they're out for the weekend, or is something being released today..?

There's a bunch of new models on the horizon from Cube. Not sure though if anyone here is interested in the details (- since Cube afaik isn't even available outside of Europe).

I'd be surprised by that as it's a major holiday in the US (Labo(u)r Day) today.

In a interview Finn’s mechanic Kevin said it’s just a saying like, “see you later”. I think it was lost in translation a bit, but he made it seem like it was nothing.

The "ass saver" style one puts the battery right in the water spray. What could go wrong?

Might as well just hard wire the derailleur in to some solar cells, by which time you might as well just connect the shifter with a cable, which can work in the dark and doesn't need ridiculous charging gimmicks

Don’t think it’s applicable to most people.  Tend to bike in the woods.


Commuter bikes on the other hand.  I know axs and commuter don’t go together for most people but I’d imagine the market for that stuff is small regardless.

A solution to a problem, for a solution to a problem, no one ever had. Excellent.

The majority of commuter bikes are ebikes now, and only more  sales will happen in the future. 

So SRAM need to bloody plug the derailleur etc into the big ass battery already so you've only got one thing to charge.

I don’t know much about solar. But pretty sure it needs a lot of surface area and a lot of sunlight.

More interested in the YT brake mount being wider than standard. 6 piston or for stiffer brake mounts?

Notice the standard pm adapter bolted to it. The big one is probably reversible to reposition the brake along with the chainstay length flip chip.

high efficiency ambient light photovoltaics are being developed with some level of reasonable promise. I suspect SRAM is jumping on the patent train nice and early on this one so once the solar tech is public they'll be set.

Also protects them from having some whack company put out a crappy version. Some patents are just to block idiots

Finallly, a wireless water bottle cage. The industry is finally listening.

Funnily enough, I think you should have stopped way back there somewhere too!
But here we are...

Anyhoo, snark aside and back to jsray's post.
I can easily see a solar trickle feed being enough to run things like flight attendant or a wireless dropper.
Maybe not the derailleur.... I mean the whole point of AXS was to stop having cables running thru the frame, so a cable to the electric derailleur would be kinda an odd choice yeah?

I am kind of surprised that there haven’t been any devices that use regeneration to charge axs batteries. Can anyone calculate how many watts it would take to charge a battery that small? I feel like you could just run a copper coil in the jockey wheel or cassette and get all of that back on a descent or at least enough to only have to charge your batteries every month or more.

It will come, but not now, as they are still milking the cow of the marginal gains, and loosing watts is a bad look. A tiny dinamo makes sense in some aplications, but it probably makes more sense in shimano's "ecosistem"

Not sure why you're getting downvoted... you can probably jury rig a dynamo/USB bank combo to charge your AXS batteries on the road, and I bet bikepackers are doing just that, but a SRAM native, plug and play, sleek and integrated, trail rider friendly option seems like a no brainer.... but it'd have wires, which is off brand. I think that and the limited market for range anxiety paranoid type folks is your biggest obstacle to go to market. Everyone else can just carry an extra battery. Jockey wheel charging is far fetched... you don't need a ton of watts but you need more copper/EM flux to actually generate electricity.

 

Or stick to cables.
