Hello Vital MTB Visitor,
We’re conducting a survey and would appreciate your input. Your answers will help Vital and the MTB industry better understand what riders like you want. Survey results will be used to recognize top brands. Make your voice heard!
Five lucky people will be selected at random to win a Vital MTB t-shirt.
Thanks in advance,
The Vital MTB Crew
I love when people are downvoting an innovation when its interesting and a breath of fresh air
Cool and fresh? You’d probably blow a load if they added a Girvin flexstem to this ridiculousness.
Whenever I see something like this bike, it gives me horrible Proflex flashbacks. Leave it to some motorcycle engineer to come up with this because his bro with a E bike asked him to do it. Nobody’s even mentioning how the geometry of this thing is completely buggered now. Remember when 29er forks all sucked because they had the trail measurement/crown offset completely wrong?
Also, dual shocks?
Roast him to his face dawwwwg.

Yeah it looks like an F1 damper, they supplied a few teams in at least the 90's and 00's and that is very much what they look like. Often shown next to mtb shocks since they are a very similar size!
Dude, they handling and geometry is very much understood here and basically the exact reason concepts like this exist at all. Telescopic forks have pretty glaring drawbacks when it comes to things like brake dive and friction so this is one way to get around it, while preserving good handling traits
Just gonna leave his old work here

RAAW retrofit kit to upgrade Jib and Madonna to make there bikes compatible with the new standard. I like this about RAAW, not making you buy a new bike to upgrade to a new standard but just selling the part to be able to upgrade it if you want, I think this is a good way to develop brand loyalty.

Vorsprung shock
Maybe already covered but Also seems like a v3 madonna on the way, but maybe it’ll just be subtle upgrades like the t type mount etc.

That's odd, I thought Steve recently said on a podcast he didn't like the poppetvalve layout of the Fox DHX2 etc, because of the digressive rebound damping and space restriction.
Why do you assume he can only have poppet valves in there?
Seems like a small valve for that... but I know the guys at vorsprung can perform magic, so I'm sure it'll be great
Not all "poppets" are equal. You can design a valve to fit the same space, that resembles a poppet valve but isn't digressive to the same degree as an X2 or CCDB shock. See the cone valve/spool valve discussion a few pages back. The design of the main piston makes a difference too - a large, solid (or close to) piston driving a ton of oil will tend more towards digressive, but a smaller piston with progressive opening shims will be more linear.
Either way, you can make different valves with wildly varying damping rates, and for different reasons so its best not to judge them on face value
New coil shock from Intend in the works?

From the associated interview: " What sets my bike apart from all others is the purple twin tube adjustable coil shock. This is something I was super excited to develop with Cornelius (Intend) as part of my master thesis. It didn’t make it to production though so now I am riding the only one of its kind and us it as the perfect suspension development platform."

Yep, saw that after. Got a little too excited there for a second.
I feel like I've come across that paper somewhere too, those are always interesting!
oh yeah here it is - https://www.diva-portal.org/smash/get/diva2:1609691/FULLTEXT01.pdf
They need better steel for their springs, what a piece of shit. If they cant source a good spring I bet the rest is junk.
Whoa, didn't even see there's an adjustable collar in there to adjust the spring stiffness. Cool idea! Integrated Sprindex approach.
I hope they release it with both trunnion and normal mounts on the shock! I love my EXT and I've used it for soon 5 years over 3 bikes because the tune, stroke and eye to eye can be changed. But It has me choosing frames with only normal mounts because of it.
Article up on the other site about a new Specialized patent for the "Under Bottom Bracket" linkage seen on the new Demo, represented by a 172mm bike that sure looks like it could reasonably be the next Enduro. Overall the information they give (some examples of anti-rise, anti-squat, and leverage rate with 5 different upper link positions/sizes) is basically right in line with newer trends of moderate progression, but there was an interesting bit halfway down the article about anti-rise:
“Changes can be made to the design of the brake mount and/or the rear braking system that attaches to the brake mount to cause the rear braking system to be positioned differently with respect to the seat stay member, but to still move or rotate with the seat stay member. These changes can result in adjustments to or tuning of the anti-rise characteristics of the suspension system.”
Is this referring to some sort of floating brake mount? The only thing I can imagine that would affect anti-rise characteristics within the wording of this section (particularly "still move or rotate with the seat stay member") is something like what Eminent did on the first AFS models (seen below).
I would say yes. Though I would prefer to use linkages and rotating bushes, not a sliding support like Eminent did it...
If I was guessing, BFRC style but with separated valves instead of back to back.

I'm certainly no patent expert, but it made me think... Could this Specialized UBB patent infringe on Knolly's 4x4? Obviously a different layout, but they're essentially the same: Horst link with a secondary linkage driving a shock.
I don't know anything about Knolly's patents other than the one about the seat tube meeting the down tube at a certain angle above the BB (which was in conflict with Intense a few years ago), but in the UBB system the shock linkage is driven by the chainstay/lower link, instead of the upper rocker link.
This has to do with "Old" tech.
Anyone have any ideas as to why PinkBike took and deliberately shit all over DVO's out of production fork in a "new article today? And Kazimer defending the decision to publish is utterly ridiculous.
Companies might want to re-thing where they put ad revenue. An honest review is one thing. Taking a bat to a company a year later?
PB doing PB things.
I’ve never paid any attention to any if their reviews anyway. Kazimer’s response just backs it up even more
Let's be honest, DVO stuff is just hot garbage, if they no longer existed tomorrow no one would miss them. For the last 3 years they were saying no one needed a 38mm stanchioned fork, now apparently everyone needs one.
Everyone has said no one needed a 38mm fork…
