the used frame market will be flooded with worthless sunday framesSo wait a minute, you mean to tell me that the dw-link isn't the holy grail of suspension designs?

Having the concentric pivot on the dropout will change the way that the bike pedals. The pedaling force is somewhat isolated from the suspension force due to the chain moving about the concentric pivot. It achieves this in a similar manner that a jackshaft does (though this suspension design is in NO way similar to a jackshaft).As mentioned, it's great for braking, not sure how it handles anything else though, why you'd do it that way etc.
It's not the latest so if you are a fashion whore, yes.
"Somewhat" being the key, since the pivot is not concentric to the BB.Having the concentric pivot on the dropout will change the way that the bike pedals.

It's good to have you back Zedro...you don't see any other advantage? Won't it at least help limit chain growth a bit? Or is it just a theoretical difference?oh gawd here we go...
it has the same system as a Kona faux-bar (irk), except for the braking mount. Theres nothing special otherwise, it'll pedal like a single pivot....

Naw cuz the main pivot still creates a different arc. Only a concentric BB pivot would do that.It's good to have you back Zedro...you don't see any other advantage? Won't it at least help limit chain growth a bit? Or is it just a theoretical difference?
The pivot "on" the axle does absolutely nothing to improve acceleration. If it did, that would go against every claim DW has ever made. Don't read into the marketing mumbo jumbo.Having the concentric pivot on the dropout will change the way that the bike pedals.

take off that linkage and the wheel is still essentially mounted to the chainstay; the axle path is still circular about the main pivot.It's good to have you back Zedro...you don't see any other advantage? Won't it at least help limit chain growth a bit? Or is it just a theoretical difference?
yeah pretty much, been out of the loop on the d.o.p.e deal tho (just a standard floater setup no?)so, essentially, from a braking standpoint, this design is similar to a kona faux-bar with the d.o.p.e. system...ie, a floater attached to the main pivot? is that the conclusion?
the biggest mystery, then, is the pedalling performance, which you speculate will be similar to a single pivot/faux-bar?
Uh oh.....The pivot "on" the axle does absolutely nothing to improve acceleration. If it did, that would go against every claim DW has ever made. Don't read into the marketing mumbo jumbo.
Yeah I was thinking about it after I wrote it. The order should have been reversed: Think first, write second.Naw cuz the main pivot still creates a different arc. Only a concentric BB pivot would do that.
just like cut first, bleed second.....wait no thats not it....Yeah I was thinking about it after I wrote it. The order should have been reversed: Think first, write second.
now theres a marketing brochure line I'd like to see:This design is much easier to eyeball and see what's going on than DW link.
but the * is a wildcard parameter...thats cheating!you forgot the little * deal in DW*link. you will find the results to be the opposite:

HAHA, yeah! Well what's neat about this, is with DW-link, a change in one small thing (say, the length of one member of the linkage) bled over into the other characteristics of the bike, whereas with the new one, it's much easier for Dave or someone else to play with one aspect of how the bike feels without changing the feel otherwise. This isn't to say that it makes the bike any easier, but it seems to be a more friendly set of tools to work with when prototyping, and may move through prototyping more quickly because design iterations can focus on one aspectnow theres a marketing brochure line I'd like to see:
"and it's easier to understand design naturally makes for a more efficient contemplation...."
I don't know.....split pivot still wins against five sphinctersbut the * is a wildcard parameter...thats cheating!

That broken hand's not only got you bitter, you've sharpened your wit again I see."mental midget" offends two groups at once.
good point, looks like a good way to simplify a design for saving $$$I would assume this design is going to replace the IH single pivots.....
This was a very important factor in developing this design. Split Pivot is not intended to replace or compete with dw-link, just complement it.good point, looks like a good way to simplify a design for saving $$$
You are a wise man on many counts...Man, I came up with this idea over 10 years ago... Infringement!
I would assume this design is going to replace the IH single pivots. Since it has a thru axle I would assume this is for the Yakuza Dh bikes. Also look at the main pivot location. Identical to the current single pivots. This design is still a single pivot, but with included floater. Looks nice!
For sure a great upgrade to the single pivoted cheaper models. Increased stiffness/weight ratio and better braking without added weight of floater. And he doesn't have to pay Tony or Spesh any royalties.
There's no way in hell these are going to replace DW link though. I can't see any reason it could perform better in ay way at all, but still a nice upgrade from the usual single pivots.
Edit: Does anyone else think the angle on the rocker is a little too shallow? Looks to me like the suspension would lift a little too much when braking, which can be worse than brake squat in some cases.
Edit again: Now that I think of it, since the main pivot is so high, the upper linkage NEEDS to be shallow to compensate. I should never question DW ever again....
submissions for the enginerd olympics requires a beer related component, like make it beer powered or the wiffle ball opens a beer for you.cool and all, but can't compete with the patent pending split-pivot wiffle ball . . . that thing is destined for the enginerd olympics
Trust me, our wiffle ball game had plenty of beer involved.submissions for the enginerd olympics requires a beer related component, like make it beer powered or the wiffle ball opens a beer for you.
actually i'm serious. It happens in february.
