Can’t know without seeing the other side but I wonder if that line splitter allows opening/closing the line to each caliper rather than running two simultaneously. Seems like a really easy way to test the differences between the systems on the fly, with a quarq sensor on there to add data to whatever the test riders report. Neat.
Formula is looking like they are onto me:

The ATC will be about the same as with a single crown 160 mm fork, so the geometry will not be affected. If the front wheel hits the downtube and/or if full squish makes the front end too low, add the tokens. If everything clears and is OK, just run it as it is.
EDIT: ah, apparently it's more like 10 mm compared to the single crown Selva. 36, 38, 40, Lyrik, Zeb and Boxxer are closer to 15 to 20 mm difference in travel at the same or similar ATC.
EDIT2: looking at the crown, comparing to the 40 and the Boxxer, it's designed to have less travel for a given ATC, the 40/Boxxer crown is much more flat. So that's where the difference comes from I'd say.

Maybe. Let us see how it will span out, when it will be available etc.
I mostly do more mellow trail riding, but man, the descents are being used. I have only 140mm rear, so I would like a 160mm fork, although tokens are one way to alter the usable travel

finally someone is listening. they are claiming production versions will be sub 5lb... interesting.
given that the current selva air forks have internal travel adjust, there's a high likelihood they'd carry that over for this.
based on the pictures and description, I'm assuming that they are using the existing Selva lowers (also makes sense for manufacturing) which means 20mm axle is going to be an option.

It doesn't. It might not bob, but that has nothing to do with overall performance. A heavy bike, even if the antisquat is dialed, is still a heavy bike.
There is no need for a FR bike to pedal badly, so to bob, but it will not be as nippy and agile on technicalities, as a lighter, smaller bike will be. And it will be more of a cow going down as well. The Hightower is more playful than the Megatower, the Megatower, based on what a friend of mine said, is a plow bike and needs to be pushed hard, to become at least a bit lively. Which means you're going really fast.

I only mentioned peddling. Check the anti squat for both there pretty close, heavier bikes are heavier we all get that.

Hey everyone, I've got a heater for you today. It looks like SRAM are officially working on an active suspension system to compete with Fox's Live Valve system. The cool thing about SRAM’s is that the controller, battery, and motor are all encased in a single component that attaches directly to the shock. It’s extremely compact and unobtrusive. In the end, this system attempts to do the same thing as any active system — make more grip by automatically adjusting fluid flow a zillion times per second. The best part: this is entirely wireless.
What do we think?

I'm just waiting for an integrated dropper/rear shock system. On a modern enduro rig post up probably means shock firmed up, and post down means shock open.
One lever to rule them all.
Integration could also add oil volume to a shock without adding more weight.

Thanks for reminding me that I took this picture back in 2019. Looks like this has been in the works for a while

Oh shit bro, do you mind if I put that on this article? Where did you take that? Can you tell me more about it? Fuck I love this thread.
Feel free! I took that picture up at Trestle. IIRC the owner was a Sram employee from Colorado Springs, beyond that I'm not sure. It looked production ready, so I'm surprised it took this long for there to be information on it

Yeah, hard pass on doubled up lever. I leave my shock open all the time.
EDIT: BTW, it wasn't as live valve-ish as Fox's system is, but RS already had something similar for Ghost, Lapierre and Haibike (the latter at a time they weren't focused only on e-bikes). Was it e:i or something similar?

Yes that's correct. I had a Ghost that was all ported up for it years ago. 2014-ish

Ya, they've been trying to do this for a long time. It appears as though the Lapierre system is quite a bit different. They took an input from the fork and extrapolated the data to adjust the rear shock because there was no sensor in the rear triangle. So, the system would sense a bump at the fork, then determine speed with a speed sensor, and try to anticipate the change to the rear shock with a delay function. It was crude, but a good intermediate step.
K2 also tried all the way back in the late 90's. The concept is there, we're just seeing refinement and iterations toward the correct answer. They'll get there eventually. It just takes time and money.
The E:I also had a cadence sensor, leaving the shock open when you weren't pedalling. It would open/close only while pedalling (closing if there was no input from the fork).

There was already some pictures of this stem on Gee's bike (Pinkbike article from Apr 13, 2021)
I find the concept quite interesting as well.
Only drawback it's almost 40gr heavier than previous model.

No surprise antisquat values are similar, how many bobby bikes are left out there? I think bob wise kinematics have been dealt with overall.
