It seems to be just springs with no damper on the unit so it's a shake weight, any momentum in the weight "smoothing" the trail has an equal or greater opposite effect, right? It's basically a Canyon KIS but for a different purpose or a fork/shock with the damper removed... aka a pogo stick.
Not hating, just trying to read through the marketing.

Yep. It's a shakeweight.
A weight (or "mass") on a piston that can damp the intensity of the oscillations ("shakes") of the structure to which it's attached. That damping can be tuned to target certain frequencies of oscillations.

Is Hope about to come out with a new version of the Tech brakes? This looks suspiciously like a bleed port, which may see the end of those messy open reservoir bleeds. Presumably if that's what it is, you'd just need to orient the lever downwards to ensure the bleed port is at the highest point (which would also allow any bubbles to flow around the internal membrane, which typically has a pretty intricate shape).

I don't think it's stupid, I have to run my levers really far inboard with a large gap between the clamp and grip, I'd love a shortened lever, but they can't really be beat anyway on power and light lever feel, except for maybe Hayes.

A lot of new regarding brakes these past pages. XTR, Mavens, Hope, and now another addition from SRAM I have spotted.
Ben Hildred is doing his climbing challenge, where he climbs 10k feet a day, for 100 days, and I spotted him covering up the caliper on his latest story - Strange, because I thought he just ran regular Level Ultimate Stealth's - But went through his old stories from these past climbs, and managed to spot two pics of a caliper, that size-wise looks like a level, but it differs in shape. It also seems to say "Prototype" when you zoom in on phone. Pic quality here doesnt really translate though.
This challenge is probably a very good test for most of the components on his bike, so no wonder sram wants to torture test some brakes. He's also running the yet to be released new axs dropper.
From his story today
Managed to see a pic with a text that looks to say "prototype" - You can also see that the side of the caliper is flat, compared to the current level brake which has a "ridge" in the side (see pic at bottom)
"SRAM" seems to be etched/laser engraved on top of the caliper

I think it's actually used more to lower the swinging of the skyscraper because of wind loading. But yeah, the most widespread use is in skyscrapers.
Yes, we use mass dampers to control wind accelerations in skyscrapers. They are basic shake weights suspended on springs. Slosh tanks are often used too. These are purely for occupancy comfort.
They can be used for strength design but then they need to be active dampers to react to all frequencies.
Because if this, they are rarely used for strength design and almost never used in seismic design (as no one knows what frequency earthquake the building will actually see).
These shake weights will improve hand comfort but at the cost of bike playfulness.

I can tell you the countershox doesn‘t make my bike any less „playful“. I mean if you want a freeride/big jumps or light trail/xc bike you probably wouldn‘t put it on in the first place.
Besides the actual weight I don‘t notice any different or weird feeling when jumping or trying to move the bike around fast. Whereas the added stability and comfort are huge.

Though it does seem like the EU ban is more "rumblings" from those in the industry than anything official. But we've talked about it on this thread before.
I'm just repeating what's been said before on the EU front, however I do know there are a couple bike releases dependent on SRAM introducing their new brakes first.

The "preference" for Mineral oil doesn't seem to have much scientific basis to it, and it is still a petroleum product so you're really just trading one evil for another. It appears that the EU and other places are looking to impose more restrictions on DOT fluid to reduce the number of harmful chemicals used, but not explicitly saying that mineral oil is better alternative.
It wouldn't surprise me if its purely a cost thing - that lack of regulation means brake companies can put what ever discount baby oil in their brakes they feel like and it doesn't need to meet any standards.

The weight on your headtube is very noticeable though when pulling up the front wheel?
I swap between a Dorado and a 180mm mezzer on the same bike.
The weight difference is about 1kg.
The Dorado is way smoother and eats the rough better at the cost of front end weight which is quite noticeable.
I assume the same would be true with a shake weight?

Ok guys sorry, I'm late to the party, but I can't find any info about that Fox fork leak.
Has anyone saved any photos or heard any rumors?

Fox asked Vital to remove those posts, so I doubt we're gonna hear anything more on the fox product side.
