 Neko on a proto Santa Cruz now? 

He’s posted other photos of that Nomad last year riding enduro. Also looks like he’s been riding the cannondale Jykle.

Makes sense. I’m sure any company focusing on performance would love to have frame feedback from the guy who’s been developing his own World Cup bike for the past two years.

I like how little material there is after the crank hole for the spindle.

The new SRAM stuff does pretty rad, but is there any advantage of the whole derailleur being directly mounted to the frame via the direct mount option? More ground clearance? Smoother shifting? Isn't that what the hangers were for..if you strike a rock and just the hanger is bent, you can sometimes salvage the derailleur - and in this case being mounted directly, just replace the whole thing? won't come cheap...

One advantage is certainly that the new rear derailleurs are much flatter and do not protrude so far.
The other is that SRAM uses its power more and its UDH dropout could become standard.

Great picture of that derailleur and I see from that angle that its flatter and doesn't protrude that much...still - seems like a really stable construction but I if a rocks strikes that, there could be more frame damage than expected..only time will tell I guess.

The UDH hanger part is replaceable. If it's plastic, it will not be as bendy as a thin metal hanger, thus won't bend as much. It will break, but hopefully the parts will be cheap to replace and will be intentionally a weak point.

Bending a hanger on a ride means you'll be able to ride out. Breaking the mount is a problem. On the other hand if I'm not grossly misunderstading how things might work, it would mean less weird shifting issues caused by bent hangers (the amount of drivetrains I've made to work again using just a hanger straightener is insane) and more user satisfaction. Unless the mounts implode on a weekly basis.

Rock strikes should be managed by the overload clutch...

Do you think those cranks could be made of titanium or more conventional aluminum?

Coming from Sram, I say it'll be alu or maybe carbon

I you look at front ant back of those new crank, it seems directly inspired by the generative design prototypes from last year.

bold cycles just released their new unplugged, wireless shifting only because there are no ports on the whole frame, brakes go through the headset of course… Sick

Nice ride, but cable through headset is a no go! Also the fat stem looks really ugly.

bigger problem is wireless shifting only IMO, what about those who want to ride shimano drivetrains?

Sram didn't make those cranks. Autodesk made them. The project had nothing to do with SRAM aside from sram uses the software.

SRAM did indeed make these cranks. If they didn't provide the desired parameters for the end product to meed into the generative design engine, they would not get that exact result.

That's like saying a set of allen keys assembled my bike, instead of saying I assembled my bike.

Completely right! There are some new features in the latest AutoCAD Release, one of them is the "create cranks" feature. That's it, hit the "create cranks" button and you're done! Awesome! Unbelievable! Woohoo

the release of the transition relay shows us that the new sram groups are called X0 and XX, the 1 in the name is gone. guess an official release is imminent.

From what I heard someone high up at Sram is heavily invested in autodesk, that's how their little prototype partnership came to be. (By heavily invested I mean a stock owning board member)

The theory is that the AXS motor puts so much force on the shifting, that the speed limitation is to avoid flexing a single shear mount when pushing the chain over. By going to a double shear mount and increasing lateral stiffness, the shifting speed can be increased.

I've looked at that new SRAM mount from several angles, and it looks pretty clever. It is much thinner than it looks. The ability to bend (or break) the slender outer part, coupled with the "breakaway" of the motor, and the narrower footprint overall, seems to be how it is intended to not just ruin everything.
