Nino still using the old shifter pod, or doesn't have spares of the new one? PotatoCam screenshot from his post of spares for Cape Epic

Sometimes I don't get the hate Sram receives.  We are all arguably on better bikes and better drivetrains because of their push for 1x.  One of my favorite bikes ever, the Kona Process 111 was able to be created because of 1x systems (Kona unapologetically designed it without the ability to run a FD).  Color me a Sram fanboy if you'd like, but they aren't afraid to shake up the status quo with new innovations.  I have AXS on my Spur and run the AXS reverb on 2 different bikes and absolutely love it.  I can't wait to see the next-gen stuff.

Tell me you're a sram employee, without telling me you're a sram employee: "AXS reverb on 2 different bikes" 

Kidding aside, if sram didn't make that 1x push, shimano would have us all on 4 chainring setups right now. But let's also be honest that sram really did the 1x push because they couldn't make a well working ft der if their lives depended on it!

Sram is awesome, but if they don't sell a decent rear derailleur without a battery, I'm out...

The FD'ers were pretty bad.  At the shop I worked at in College, we would use the rotor trueing tool on the FD cages to bend and shape them to operate better.

Also, in reality, with so many bikes go 'E', does anyone really need a 52T?

What makes you say it looks heavy?

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.

Which cassette do you mean by 11 speed 10-46? I am only aware of the 12 speed 10-45 that was initially designed for 2 by 12

Was already talked about at some point, it’s probably some sort of sensor that works with the shock

that's a sensor for that electronic shock from fox, should be on the rear caliper too. jesse melamed and others where seen with it last season while testing that electronic proto shock.

I do not thing, the new AXS derail. will be necessarely heavier. However, I am not buing AXS until it will be weigh-wise comparable to the mechanical derail. Based on some proto data, the cassette should be roughly 30 grams lighter than the current eagle 52.

They did/do a 10-45 that was for the 'race' xtr groupset. Basically just the 12sp 10-51 with the largest sprocket removed (11 speeds but still 12s spacing).

I have the 11 speed XTR HG+ cassette on my SJEvo. The product was announced (allegedly at the request of sponsored Pros), a few samples were produced, then due to the factory fire they removed it as an option. A few of these cassettes float around out there.

First Look: Shimano's New XTR is More Than Just 12-Speed - Pinkbike

+it's actually 10-45 I see.

It's basically the 12 speed, with the 1st gear removed.  It's lighter but mainly I just don't waste time going in to a 1st gear I don't want.

Because I wax my chains, frankly I experience very little driveline wear.

Oh yeah. Nice one.

Same with the Scylence hubs. We had a good few come in on bikes. Some of them were beautifully silent... others not so.

Haha!  I love it!  Sometimes when you're working on a project and you're not getting the results you want, you need to scrap it and come up with a new plan.  If making sub-par Front Derailleurs got us to 1x systems, I'm OK with that.

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!

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

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

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.
