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.

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.

Can confirm my 210x55 Vivid with Levo mounting hardware weighed in at 674.4 grams. Supr Deluxe Air weighed in at 478 grams for the same length. 

My 230x65 Super Deluxe Coil with RS coil (500 pound) came in at 1,040 grams

Blimey, I got off lightly...

Sorry.  Does anyone have any news on a new Scott Ransom?

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. 

I think the main drawback with the lefty is that damper and airspring have to be on the same side in the same tube. That puts a lot of limitations on the designs and sizing of both, I believe. Might also complicate servicing. Some people swear by them, I've never ridden one so have no idea? Why do normal two legged forks not use needle bearings instead of bushings? Achieving the tight tolerances and near mirror finish required is easier on a shaft and bushing than three (or four) flats and corresponding housing. Two legs would have to be aligned and clocked instead of just aligned. Thus more chances for binding or added friction, the tolerancing would be a nightmare. Also needle bearings would have to run on hardended and polished steel inserts, aluminum just can't take the surface pressure from them. So weight and even more complicated manufacturing. That's why bushings are the norm. 

Edit: lefty size limitations are worsened as fork travel increases as well. Probably why lefty stayed in the xc to trail realm. Out of curiosity anyone know what the longest travel lefty was?

Supermax was at 160 for the Jekyll. All that makes sense. But I know with mordern manufacturing it is doable. Hell, they could add a Vorsprung secus like, negative chamber. Just seems like a good way to go when you want to make a very precise feeling fork, keeping weight down, and making it strong. Or even then, intend bandit. That one definitely surprises me that we do not utilize that sort of design more often. Having a Zeb lower with an air shaft side Boxxer stanchion. Id buy that for rough trail riding.

A lot of things are "easily" doable, modern capabilities or not. The limiting factor more often than not becomes the price.

$2500 “transmissions” would lead me to believe that price isn’t actually the limiting factor, marketability, aesthetics, and what they think will sell likely has more to do with it.

How many people do we see riding around on factory level suspension that don’t actually know how to, or ever bother to check suspension sag.  Price can’t be the issue

I'm guessing 'bzt bzt' sounds are much more easily sold than buttery smooth suspension. Can't see/hear the buttery smooth suspension. And your factory level suspension comment confirms it even more Tongue

New Lapierre Spicy incoming. 29 or MX, 180 front and rear and suspension layout à la new Mondraker Summum. Price will be high and no pros ridden it yet...

Specialized does own the Trust design now. Though my guess is we will see that on gravel bikes from them.

Clearly the next big innovation in forks from rockshox will be a stanchion coating you can ice skate over ;p

Ergon grips on TB bikes look like something new

Yep i noticed that aswell.
I know its not new but a few people I know would really benefit from going down in front rotor size as troys mechanic describes.

They announced them a month or so ago but AFAIK aren't available retail yet.  Pros have been running them all season.  I agree, they look like an interesting alternative to ODI Elite Pros - maybe a little bit more cushion on the outer edge of the grip before the flange.

The Norco DH bike is part of the team bits and the progression adjustability without changing shock settings has been mentioned again. Maybe it's adjusting progression but keeping the sag point the same and that is part of the reason settings don't need to be changed? How does this work with other systems that enable progression tuning, does the spring rate need to be adjusted when you change the flip chips?

If you keep travel the same and increase progression you usually get a higher leverage ratio at the sag point. If you keep the leverage at sag the same you generally loose a little travel. On a bike like the enduro, the flip chip does actually increase average leverage ratio if you put it in the high setting. Fairly similar to running a mullet yoke on that bike as it’s only something like 1.5mm shorter. Lots of bikes have changes to kinematics that aren’t mentioned when talking about what a particular flip chip does. It’s more of a question of whether or not the change is large enough to care about.

At 2:12 the disc looks like an updated version of the Galfer Shark Disc without fins and 4 rows of holes instead of 3.

Might be missing something, but has anyone else noticed that the new SRAM calipers are 90% of the time only on the rear end with the current caliper up front? Interesting how a rear specific caliper might be different... I know Troy runs a bigger rotor on the rear for more power, so maybe it's to do with a power increase?

Isn't the trek running a smaller rotor in the rear as well as mismatched calipers?

Nope, that’s the prototype TRP rotor they are testing. It indeed looks a lot like the Galfer!

On the proto SRAM caliper, I don't if it's already been noticed (can't recall), but there's actually 2 protos. Can't upload 2 pics on the same post though

We know that, yeah. The blocky, black one is the Maven, running mineral oil, then there's the red caliper that's probably running DOT oil (on a standard Code lever).

New slash coming with a higher spec alloy frame option as well as carbon. The idler is friggin huuggggg. Mullet only as well confirmed, that proto floating around is accurate.
