New maxxis pattern spotted on Brendogs instagram. Looks like it bridges a gap between the shorty and assegai maybe? More spaced out and looks taller than assegai.
But doesn't show what the bottom two links do through the travel. That's the juicy part!!
It does show it? Top link rotates anticlockwise, lower link clockwise. It’s a nice square side on view as well. Someone with more time on their hands than me could whip up a model in that linkage program.
Not sure if it’s been discussed earlier, but it’s basically a four bar with a linkage driven shock. All be it the link driving the shock has to flex in order to work.

WC over and the boxxer / vivid still not relesed. I wonder if they have some production issues?
I don’t know what is going on…
Word on the street is GX Transmission was supposed to be released last week, but clearly it wasn’t. I know that embargo is holding up a couple of bike model releases.

It really depends on where the flex occurs, it could effectively be a 6-bar with the correct flex.
Yeah, it does show it, yeah, it's obvious where the links rotate (counter rotating), I was interested in seeing some more travel happen to maybe see any inflection points in the movement. If I understand it correctly, Yeti's Switch Infinity, Ghost's dual short link, system, modern DW link layouts (four-bar), Yeti's 6-bar layout and maybe some more achieve good antisquat by extending the chainstay around the sag area, then through the inflection (one of the links starts moving in the opposite direction) the chainstay starts shortening, lowering the pedal kickback.
This is something that can't be done with a horst link but is something that might be possible with DWLink6 with a very similar layout to a horst link. That's why I wished we could have seen the complete travel. In the video they appear to cycle it riiight up to where the inflection point is and the links should start co-rotating (top link moving downwards).
WC over and the boxxer / vivid still not relesed. I wonder if they have some production issues?
Considering the state of the world post-covid, I would be surprised if there WASN'T production issues. It's going to be years before we see consistent "normal" production cycles. It wouldn't be a bad thing if they let more of their athletes get a few events under their belts and report back before doing a full launch
Pretty sure this has to be Vittoria with some skin in the DH game now..? What you guys think?

Looks to be a standard Mazza as far as tread goes. Last summer there was a vittoria rep and a sponsored rider at some eastern states cup races running Mazzas that had the same red hot patches. Kinda got the run around when I asked about them but can assume it’s just some slightly stickier rubber and maybe a bit of extra flat protection (for what it’s worth their enduro casing was pretty bulletproof to begin with compared to doubledown or supergravity) looks like every tire brand was having trouble keeping air in every riders tires at Lenzerheide.

Its definitely not a four bar linkage.
The chainstay is attached via two links are therefore has a virtual pivot point for where the "main pivot" would be, the seat stay will flex, meaning if anything, you could argue its a linkage driven "single pivot" where the single pivot is actualy a floating virtual pivot point.

The big red hot patch was debuted on their new Syerra 'down country' tire (that is actually what they call it) which is their newest MTB tread. They also started releasing multiple casing options for tires though I didn't hear much news about it. The old ones were all 'TNT' branded but now their is heavier TLR casings (only available on 'race' tires, I think they are a softer compound) and 2-ply tubeless (closer to TLR weights but I believe still harder compounds). I can't find any real world pictures of the 'race' branded tires so it may be that is just the way they will brand those. Hopefully it is all a return to DH/Enduro for them as their road and gravel tire offerings have been pretty solid for a while.
On a (vain) side note, it is a bit unfortunate that the hot patch is so big and so red, that would be hard to match with certain bike/kit colour combos.
So yea the pivot for sure needs flex somewhere in the system to unlock it. I did a suuuper rough model and measured the angle between the seat and chain stays at roughly bottom out (dont know shock specs) increases by around 0.3°. Where they're getting this I'm not sure. rear end looks like it built like a brick sh*thouse. (model not to scale).
They get it all over. A wishbone structure like they have here is not particularly stiff when you try to open it or close it. Adding a vertical brace makes it stiff (that's why triangles are so stiff).
The thing is unless there is some magic going on with the layup, the chainstay and seatstay both curve all along the length to achieve this change in angle. Which is likely coupled with optimisations in the geometry of the links to require as little flexing as possible going through the travel.

Yea makes sense. The frame will be flexing all over the place so not hard to imagine a 0.3°ish flex in the rear end. Definitely looks like the have laid out the hardpoints to minimise this figure as much as possible. Maybe also why they got rid of the vertical race compared to the non jack shaft bike?
Cool design though, I really like what it does with the axle path.

What the high pivot bike is compared to a DWLink6 bike (the Athertons) is like what a flex stay single pivot (XC/Stumpjumper) bike is compared to a horst link.
The normal pivot height bike is a standard DW Link and thus has a vertical brace. It needs it, it wouldn't work otherwise.
@Sonofbovril2 shows the linkage in about the samepart of the travel (and not any further) than what the video showed. And I'd really prefer a video/animation to see where it flips over (if it does of course).
@krabo83 it appears they are more or less parallel to each other and were tested back to back in NZ.
What are the chances Jordan Williams is on the Demo Prototype at the next race? Kinda crazy that he beat both his teammates (and everyone else) on the "old" Demo. It's still incredible that all 3 specialized riders were in the top 5.

The demo he’s on is a custom size for him, I can’t see him jumping on the new frame design this season, he clearly has something that works for him. and the next race is this weekend….. so unless he has already been testing the new bike in the background, then I can’t see it happening. I also heard that even the prototype of the new frames work costly, not that would be a problem to a company like specialized. But Loic stuck to the old frame last season when Finn was already on it, to me that indicates that it must feel like a different bike to ride…. and getting to that level of speed and composure that Jordan show last weekend would have to be done on something you feel 100% confident on. (Only my opinion, could be wrong)
Looks more like a Pirelli scorpion M
speaking of pirelli, anyone seen what tires loris really was on? :D

Yep you’re right. Thought brendog was maxxis sponsored but it appears he isn’t. May be doing some testing shopping around for a tire sponsor.
Maxxis DHRll by the looks of this…

My guess (hope, I will buy a Vivid the second it hits), is Eurobike.

Pretty sure this has to be Vittoria with some skin in the DH game now..? What you guys think?
It definitely IS vittoria, they did a nice closeup of the branding when Hugo Frixtalon finished with a puncture.

It wouldn't be a bad thing if they let more of their athletes get a few events under their belts and report back before doing a full launch
Hmmm, looks like a proto Rock Shox Sid flight attendant on Nino's Scott.
About time! The sooner we can abandon cable lockouts, the better
Quick overview and demonstration of Suntour's new electronically controlled suspension system. Looke pretty dialed.

Its definitely not a four bar linkage.

🤯
Making it a linkage driven four bar.
Yeah my mistake, I was confusing the terminology of Horst Link and four bar.
Correct, it could be considered a virtual four bar system.

Here’s a nice pic of the links under compression
so is this a newer or older prototype version in these pictures than that radical one that's been raced? didn't have time to read the article.
