I'm an 11 speed guy and personally find the really low 50-52t gears counterproductive to forward progress no matter how steep the trail is. But then I only run 30T front chainrings on my 29ers, not 34s like Nino and the boys.

I've had AXS since it was first released as a group set, and really it works amazingly well and took all sorts of abuse. It's on my wife's bike now. I only got burned once on a bike ride by a failing battery.

That said, I went with X01 11 speed on my DC bike and knocked off half a pound of unsprung weight compared to AXS. The AXS derailleur weighed around 350 grams and the new one looks even heavier. The 12-speed cassette weighs about 360 grams. Compare that to about 242 grams for the 11-speed cassette & 210 grams for the mechanical derailleur (not to mention better ground clearance). The mechanical combo gains some weight back in the shifter and cable but it's located as such that it doesn't matter. That's enough weight to matter and in the end, I actually preferred the mechanical shifting. I have tried to climb the REALLY steep stuff on the 42t, and it's too hard for me and I suffered which is why it's on my light duty DC bike, not my big bike.

As such my big bike has a 12 speed mechanical XX1 derailleur, an 11 speed X01 shifter & the very rare XTR 11 speed HG+ cassette with a 10-46 tooth spread. I find this to be my perfect combination.

I plan to just run 11 speed X01 on my new Relay.

The new groupset should be amazing and I really like SRAM products, but the added weight at the rear wheel just seems to be a significant negative.

It is all about the use case. I used to share the same mindset about Eagle cassettes being silly until I moved to the mid-west where you have mountains as opposed to rolling hills. When your local trails have long 200-800 meter climbs at an average gradient of 10-15% you definitely need gearing to keep you in a sustainable wattage and cadence. 

Example: On a XC bike using 32x42T gearing and climbing a local popular segment with 400M ascent in 3KM distance. I measured almost 260W NP for 32 minutes. When you have 2+ hours of climbing per ride, unless you are a elite level athlete with 320+W FTP, it gets tiring. Now consider a 35LB enduro bike with sticky and draggy tires. 30T/28T + 10-52T nets your about the same power numbers. 

It is a given that these uber wide range cassettes are here to stay because they are versatile across multiple riding areas. The AXS app can help see your time spent in each ring so you can size the chain ring appropriately. In the East coast a much larger chainring (34/36T) is better suited with these cassettes.

Also feel bad for the person from France who got roasted for having a 24x52T low gear. They're in the Alps!

Please take the gear/weight weenie discussion somewhere else, this is a rumors forum.

I doubt it as you can already buy it from Stages.

I have seen one on a recent trade show in Germany.

 Looks Like SRAM offering some new Level brakes soon. If you Look closely, you can spot the new SRAM Eagle flattop Chain in the second Picture.

With the upcoming levers having an angled fitting for the hose compared to the bore of the master cylinder... How will the stealth-a-majig work? It won't be as simple as it is now where the same spring is used to block the port upon removal of the hose and for the piston return.

 Looks like the cover is off. A distinct lack of side-profile photos and weird cropped photos.

Probably just the telemetry mount?

Hey dude, you’re supposed to be the focus of tech rumors, not the source.

It is not a hole. You can see it at the first Loic's insta photo.

Bike looked like it was working so good. Loic was just standing still with the bike floating under him!

Guess the cover isn't gone; it's just evolved

(edit - it might actually make sense for Specialized to keep it this way for release. looks like a much more polished way to seal off whatever's under there than the fabric)

What was the green light on the LHS side of Loic's handlebar?

He's running motion instruments all over his bike so I think it's just apart of the data acquisition system

Back to the carbon covers like he had on the last bike. Almost makes it more intriguing because we can see more, but still understand nothing about what is going on.

Yep, looks like the carbon cover and electronic lockout have made their way over to this bike. Jack is a mad genius.

Obvious choice would be some sort of mode light for whatever is attached to his suspension.... It's also been speculated that it's some sort of split time light to show if he is on time.

If it's not sealed sealed, the dirt will build up under it. Which is worse than having it all open.

 

@sspomer nice one with the filename, thought it was Jesse at first :D
