Needle bearings carry a lot of load for their size (the surface area of the race and rolling element contacting each other is high, thus the pressures are low), but there are hardly any needle bearings out there that come as a cartridge, with seals, they don't carry axial loads (deep groove ball bearings hold up surprisingly well in that regard), etc.
For specific applications they can be great. In a shock eyelet I'd give them a pass. DU bushings are way too cheap and modern bearing mounts work too well (I'm on my original bearings in my Super Deluxe after 4 and a half seasons and 450+k vertical meters of descending).

Only time I see needle bearings that last is in the wrist pin on a 2T engine. But that is oiled by the premix and pretty clean. Also high speed lower loading than suspension bits.
What about about Bearings like Moto’s and I think Push uses? Seems like the best solution to me. Allows for misalignment, side loading and of course axial rotation around the mounting bolt.

Spherical bearings were discussed above as well, yes they are superior to every other option in terms of performance, but they don't last too long because they are typically not sealed that well. Argument that you cannot fit them because there isn't enough space is complete bullshit, price and weight, those are real reason, 16mm OD is size used on those shock that use them, vs 15mm standard eyelet.
Been around since Ohlins first partnered with Specialized and discovered the joys of shock yoke extensions (esp. the ones that Specialized used to use that literally bolted the shock to the yoke)
Can’t say I’ve seen this bike before, so I’m guessing it’s something new from fezzari? That’s nik nestoroff on the bike. New dh bike? Or long travel bike with a 40?

What happened here was. it a huck to flat or something or did the new GT literally implode ? "There I was just riding along"
It was JRA during a practice run at Val Di Sole if I remember correctly. Granted, a world cup racer's JRA is beyond my mortal abilities. Frame was probably damaged at one point. Forgot details.

A big factor would be frame tolerances on cheaper bikes too, the minute you dont have nice alingment and that needle bearing has to take some axial load you would start to get issues.
Push's spherical bearings would be the best solution no?

"Another aftermarket element to the Vivid launch is the introduction of RockShox's Bearing Adapter Kits, which can replace the standard DU bushing mount with bearing hardware, where frames allow (8mm ID x 30mm hardware required). This kit also fits the 2023 SuperDeluxe Coil shocks, adding some tuning options to the existing lineup. Bearing mounts can help reduce friction in the linkage, and improve the sensitivity of certain kinematics quite a bit. The Bearing Adapter Kit costs $30 USD."
Interesting to hear a bit more about this one too.
The service manual has the how-to installation, might tell you something. Yay to another single use speciality tool!
The new vivid has the option to upgrade the reservoir to go from a select or select+ to ultimate version. I am curious if the same is possible for the Superdeluxe ? I know the ultimate version of the SD reservoir are available as separate purchase but nowhere it says if it's possible and compatible. -A select+ SD air owner that would love to upgrade to ultimate without having to buy a new tuned shock.

In this case I think it might have to do with manufacturability too. Machining a square tube and slapping some hard steel on it is easy compared to machining grooves for balls and needle bearings also give torsional support so you can actually steer with the single stanchion fork.
And it's also smooth as hell compared to bushings (apparently).
For the 65mm stroke vivid, claimed weight is 670 grams. I just weighed my Cane Creek IL with a 450-550# coil on it, 63mm stroke. It is 720 grams. The EXT Storia is lighter for this size, but I don't remember off the top of my head the exact weight. Kinda kills the point of an air shock for me if I'm only saving 50 grams.

Blister claims 703g for an 8.5 x 2.5" Storia V3 with a 375# spring, so I'd assume the EXT with a spring that would fit you would still be a fair bit heavier than the Vivid. It still isn't terribly far off if you have a light spring weight, though, which is interesting.
I'm just happy he walked away from that. I've got one of those bikes and am not too worried about it. Though I am wondering if the green ones may be cursed. Wyn was on a green one when he crashed and broke his hand, Roger was on a green one. None of the other riders have had any issues (none others are on green ones) things that make you go hmm

Are you seriously worried about 50g difference in shock weight on a 63mm stroke shock? I could cut my hair and lose 50g 😂
In my case where in the total system, the bike is maybe 20% of the weight, 50g especially on a performance suspension component is a trade off I’m willing to take.

The 205 mm 2021 X2 I have here weighs 663 g with hardware and one spacer. The 2021 Super Deluxe Coil that replaced it on my bike is somewhere around 900 g, give or take, with a standard Rockshox 79 N/mm spring.

Im probably going to get ripped apart for this, but it really surprises me that we do not have more forks like the Lefty or the Intend Bandit. It was not perfect, but given the more recent capabilities in manufacturing, we could probably make it a lot better these days. Ive heard from many (at the time) that when it was working normally, the last iteration of the Lefty was awesome.
I know some hate the look of them, but we for some reason we have accepted massive pregnant downtube bikes to be a thing, kind of. Maybe Im not disturbed by lefty because I have not very symmetric body so its okay with me. I dont know just has me wondering.

you’re comparing a coil in-line shock designed for a Spur, with an air shock (with piggyback) designed for a Spire or TR-11, and are surprised that they are in fact close on weight?

Lefty had needle beerings for that reason.
Any indication if the model-specific shocks available aftermarket or are these just ones that will be coming on stock builds?
Some shops are already listing the model specific shocks.
