Formula has foam spacers, so they compress with rising air pressure in the chamber and give some more linearity - with added plastic volume spacers, you ramp up the spring very quickly, this takes some of that ramp out.
As for the decoupler, they have a floating-ish piston, which means they lessen the piston bind when the fork flexes.
What the buttercups do is different, they take away the chatter that isn't covered by the spring in the fork (due to stiction and the like). So the same as a rubber top mount in a car (with flexible rubber bushings in the links taking loads in different directions). What bikes essentially are are race cars, where everything is solidly mounted, more or less. With race cars this is done for performance, as it gives precision (less unwanted flex and movement of the wheel) at the cost of comfort - that's why this is not done for road cars.
As for the wheelbased article, didn't read through it, but the pictures only cover the buttercups, yes. And the one that has a pin going through is done that way to prevent a 'dead' rebound adjuster - the rod needs to be rotationally fixed to the chassis in order for the dial to turn the screw inside it. Otherwise everything could rotate and the clicking of the dial wouldn't actually do anything with the rebound setting.
As for the IFP aspect, true, the charger already uses it. But it's spring backed, not pressure backed, as it is in shocks. There is no spring in the patent application and I think items 347 and 348 are just the compression rod/assembly and the bladder.
What an IFP would add is some more stiction in the system, but easier servicing, as you'd only need to replace and O-ring instead of the bladder. But Charger dampers are technically unserviceable anyway (to the detriment of angrybikemechanic: https://www.instagram.com/p/CaXw90esxmU/ ).
Fox's (Marzocchi's) solution with a cut in the rod to bleed away excess oil is also a wonderful solution when it comes to oil ingestion, but it does require you to run the same damper and lower lubricating fluid, which might not be the best, depending on the design of both the bushings/chassis and the damper.
Yeah thats a good point about the elastomers. I definitely like the idea of more comfort but I don't think the Buttercups are the best solution.
I do like the idea of easier servicing though and I haven't been impressed with the current charger damper. I'm no engineer and I don't quite understand what makes a good damper but I feel like both fox and rockshox have fallen a little short of the mark.
And as for marzocchi the old ones seem to have it somewhat right. Personally I like the idea of an open bath damper a lot more than the cartridge systems we have now. Running more oil in my option is not a drawback. It seems to keep everything running smooth at the expense of some weight and old leakage. It also works for Moto so I think it should work on a bike too.

Replacing the bladder is a good thing, as they have not been the most reliable when it comes to holding oil, and they have actually not been available as replacement if they break.
Regarding open bath, you have the risk of foaming of the oil as it will bounce a lot inside the stanction. You can somewhat negate that using a lot of oil and putting the compression damper at the bottom, but that is adding a lot of weight, which is undamped weight.
Conti tyre release date: April 8th - Very little stock being spread world wide to begin with, major stock rolling in October/November
New trek E-Bike: Lightweight trailbike spec, basically a Specialized Levo SL. Rolling out in a few months, no solid date as of now
New Pinion "AXS": Currently in development with real world testing expected to take place from July. Benefits from this is that you'll be able to change gears without having to stop pedalling.
Zerode DH Bike: Zerode are currently making a new DH bike, expecting it to come out in time for next season.
Dean Lucas is currently riding an alu frame, not sure if it is just because of shortages or if it is slightly different. Also, on the latest Making up the Number podcast Matt Walker confirmed they are on a revised front triangle with some minor geometry changes.
Pivot released an updated Switchblade but doesn't seem to be any press? I guess just minor changes with seat tube and colours? not sure if geo changed?
I hope its a white bike but I also want to hear more about this ohlins shock its surly time

A friend send me a picture from that Shock without the cover but i ganz Upload it here. And you didnt see that much were the compression adjusters was are now Something mechanical covered in ductape. But you cant really see what exactlys going on there

New HT X3 Pedals

Gwin also riding them. Looks like the plate to help Clip in is the biggest difference.
I guess anything that uses an idler would be a high pivot, but that's not very high at all. It seems more in line with the GT Fury. Still a very cool bike, but I feel like we should call these bikes mid pivot or something like that.
There have been test pilot tires with existing treads for a while now, the ones I’ve seen in person have another layer of pinch flat/sidewall protection compared to DH casing and was told they’re crazy heavy (in the realm of 1500g or more for a 29 DHR2)

vali's session from our pit bits vid - idler different (not enclosed like loris/reece etc bikes). is this what was going around a week or so ago? new slash rear end or something?

Anyone know what the bike is in the foreground? Seems to be hiding in a few other shots as well. New Megatower?
