Possibly related, in the recent MBR video about the new Levo, there is this foam model next to the one of the designer's desks:
In the (possibly relevant) rendering above the models, it looks to be a bike with a single crown:
Yes yes yes!!! Finally some movement on the new Enduro! Maybe it’s not too far away. Spesh always strategically place some Easter eggs in their videos, nice catch!

I can't figure out why anyone making an inverted fork in 2025, especially a single crown inverted fork, wouldn't use the Manitou hex axle to add torsional stiffness. The patent is expired and it adds almost no weight. I imagine a 15mm hex axle is significantly stiffer in torsion than a round 20mm axle, and doesn't require a new front hub. Especially if you're already doing pinch bolts, you can do it the way the Dorado has been doing it since 2002? It's so simple!
We'd finally settled on Boost 15mm as a trail bike front hub, and now it's blowing up again. Sigh.
They axle isn't really in torsion though (that would be both legs rotating opposite way around the hub) so I'm not sure how helpful is? A 20mm axle or maybe torque caps are probably the better options out of what already exists

There are a few people who I eagerly await pre-season race footage of, top of the list is Loic and based on his recent story I'd say we aren't disappointed. New/Raw brake calipers, possibly uncovered rear shock finally, new chainstay, new/kinked seat tube? There's too much and yes I am hoping someone posts the screenshots for me.
Essentially an aluminum Pivot frame with hopefully non super boost. If it turns out to be cheaper, they will sell heaps most likely. At least in my thinking

There is a component of torsion and a component of bending. For the wheel be misaligned with the bars/stem, one fork leg has to be angled forward/backward (however you chose to view it) relative to the other. An easy way to visualize this is hold a bar straight out in front of you firmly holding one end with each hand and try and pull one hand down. Then do the same thing but with one hand very loosely holding the bar. It becomes much easier to lower the one hand and the bar will rotate slightly in the hand with a looser grip.
Gotta admit I'm pretty excited to see this upside down fork battle play out, I'm guessing more manufacturers will join the race. Both Fox/Cane Creek protos look dialed, the CC takes the cake with its machined looks but I'd happily ride either.

Forgot about that and props to Primoz, it is an insightful post. However, it is only looking at wag and not roll. If he did include roll, I'd venture to guess the results would be similar though, the USD is not as stiff as a RSD. But the nuance of the whole game is what is the right amount of flex/stiffness/compliance?
I think a lot of the roll in the rear wheel is generated by the way the frame is designed and I would not be surprised there is fairly little (compared to the rear) roll going on with the front wheel. You would be twisting the wheel basically towards the stanchion where the fork is the strongest. I'd guess most of the loading generated in this direction would be deflected to a different axis/plane just due to the structure of the fork, it buckling out of axis, etc.
If we are talking about roll specifically, I would not be surprised if roll was a much bigger factor with USD forks (no bridge) than with rsu forks (I also tested a bridge less RSU fork in that analysis and it's a noodle) but at the same time I would be surprised if the main factor generating roll was rider's inputs vs. The fork itself - the forces generated by the spring are not the same as the forces generated by the damper, on the return stroke they are not only not the same scale, they are even working one against the other so actually working really strongly to generate roll. With an USD fork the stanchion-interface-to-dropout, dropout itself, the axle (diameter and thickness) and it being clamped into the dropout and the hub assembly is the only thing preventing roll generated by the stanchions moving unsynchronised.

Clamping down on the axle is what improves torsional rigidity of an usd fork. Besides bending the stanchions also twist a bit and also twist around the axle. Clamping that down makes it a bit stiffer.

This looks like a good way to get rid of the vulnerable pull link that was hanging out under the BB on the last version of the Demo prototype. But I'm surprised to hear it has "pretty high anti-rise," and I'm also curious what numbers you think are pretty high, aka above or below 100%
Specialized has been on the very very low AR program for a long time, in the 40-60% range on the Demo, Enduro, and Stumpjumper for years and years. I would be shocked if they went above 100% on the new Demo, and that would represent a big change in suspension philosophy for them.
They were also promoting very low anti squat (or even pro squat), no chain growth, very little to no progression at all etc. And here we are 🤷🏻
Reminds me of the coffee related named Marzocchi models from before they were bought out by Fox...
Nah cappuccino coating was more like bronze color and also very shiny. This looks almost like matt in appearance and shade is also very different. Performance wise dlc/pvd would be most likely the best option and not too hard to get, colour options are in that region as well

Actually, it was called espresso 🤓. I had a 350, good sliding but boy that thing went down as fast as butter on a hot toast.

Heh not it seems the Mocha one is the closest I think from the color palette I posted above. As long as it's not latte macchiato coloured it's fine by me 😁

Towers are not tall enough. Said to be a new 32”. Going to be called MegaSkyScraper. Remember me as I just leaked the companies biggest news. Theyre coming for me.
This one looked like a motor was possible.
No chance they are 5DEV, Loic wants to get to the end of a run with 2 crank arms!
Yes yes yes!!!

Yeah, gonna be a big shock tunnel for an enduro bike, that's he first thing spec should improve.

Turner back in the FS game?!
I don't think the Spesh team leaves that much to chance.

The big question regarding all these new USD forks is, where are we putting the mudguard?

It's not hex axle, more like square with rounded edges. Nothing new from them, it's a same design as helm forks used from the get go.
There's a chance he is so fast because he wants to finish before his cranks explode.

Your chin is the mudguard now 🤷♂️
Will it be the return of frame mount mud guards?

Yeah, cappuccino would be much lighter
Does anyone know something about a new Megatower?
