Any news on "Split Pivot" ????
I thought we would be starting to see bikes by now?

DW's new suspension design. the split pivot.

- Start date
News, yeah, I have some of that...

Doesn't Trek have that?????? At lest the Trek Remedy I had looked like it did.Any news on "Split Pivot" ????

DW, I'm just curious how is it possible that TREK can sell the same idea of concentric rear pivot like your Split-Pivot is? Especially if your patent application predates TREK's attempts by 1 year. Has there been any agreement between you and Trek ?
It looks like Trek just used Hugo Becker's old axel pivot patent idea of simplicity and added a floating shock and patented the combination?
google patent application searched it and the trek patent and it just seems like a combination patent of simple rear and floating shock the way it reads
Anyone else try to figure out what all these patents say???
Now I'm not sure if DW's patent mentions even floating shock possibility but I remember DW talking about "very strong position" of SplitPivot. And if he hadn't forgotton to include floating shock arangement in his patent then Trek's ABP should be out of game. Or ... ?
In any case like this, a patent portfolio is enforceable once it issues. Although the Split Pivot case is in the advanced stages of pending, it still has not issued. Once a patent portfolio issues, that only gives the patent holder the license to go through the proper channels to protect the idea. In other words, you can legally file documentation with the governments of the world, and try to get the infringing party to respect the patent holder's intellectual property. This typically costs millions of dollars, and in the end it's a disaster for both parties. Trek has a prior history of being a very respectable company, and I have high hopes that the Split Pivot situation will be rectified amicably well before anything damaging happens.
Yup, the floating shock arragement is mentioned in great detail in the Split Pivot applications and illustrated. Take a look for yourself.

So, once Split-Pivot patent is issued Trek will have to stop selling their entire ABP related line-up and wait till SplitPivot runs out. Is it true? And patent-pending stage of patent process allows multiple applicants to sell identical ideas simultaneously until the 1st application is issued?
That is cool it covers the combination of floating shocks. But how is it better than the mechanical system of the 1890 patent that also has a concentric pivot? aren't all concentric pivots the same and can just be tuned different by the rocker and shock locations like all that have done single pivots before?
Pretty cool however it works out. I look for more out there after riding the various treks with split pivots. When is the first one from DW coming around?

Read through those patent applications for Split Pivot that I posted up, I'm sure you can figure out the difference! My lips are sealed on dates, but I've seen and ridden bikes, and I am happy with them for sure.
it is a bit hard to read, are claims 1 to 72 still in the application or just the other next hundred? Definately more words that the original patent in 1890 that is just a picture and a couple lines to explain pivot on axle. Pretty fun that easy back then and now so busy words how to connect a shock to a single pivot
So split pivot seems to be the 1890 split pivot bike and then combining desired tuning linkage styles like a kona walking bean or a fsr rocker linkage?
Always cool to see stuff so I have more to play with on the trail. Thanks for keeping us up to date and hopefully someone can find you on the trail on one of these sweet and interesting prototypes.

jeebus, Steebus, ya just gotta go down the document a bit to see the law firm listed! Sheeshus!
too many words in said article
Dave, can you tell us whether or not may we expect new split-pivot bikes presented at Interbike and/or Eurobike 2009 ? 
Over 150mm (6") of travel is preferred.
"Yes" or "No" is enough answer.
Actually I'd love to see some competitors to TREK's new Scratch model.

140/150mm of SplitPivot action coming from our camp... We might even be ready to sell them by this time next year! The engineering (both kinematics and structural) has been done for months, but finding the time(mostly)and money(also a big one) to build some test mules has been a sticking point. We have 2 different main-frame designs we're playing with. Stock frames will be exceptionally light (a 23# slack angled bike? yup) and we will also be offering custom builds for heavier or more "abuse" oriented riders.
Stoked!
Sexy time - hope find the resource soon.
Me LIKES the front "triangle" in the image that you posted... I'm a Short rider...It's all about clearance Clarence for me!

Not comparing...by any means... but just for my own memory, etc.... VooDoo? Or a THICK. Just shock angle... No one...Pu-lease... start raggin on the comment....
This rear by NO means compares to the two just mentioned... just what it reminds me of.... (been around too long to have someone take an offhand comment like I just posted and have a thread totally go off on a tangent..)
Immediately reminds me of a ventana front end:
http://www.ventanausa.com/frame_labruja07.html
with one of any of the shock positions.
It's a good thing none of that matters, because it sounds like it's extremely well thought out and I do love spooky bikes. Can't wait to see the finished product.

Sounds flexy, needing shims, and needing Rootbeer paint job.
BTW I want a DW link frame that is U.S. made. (and I know about the Turner)

me too. i wouldnt peel off that "made in USA" sticker off like i did on my Revolt's "made in taiwan" sticker
This sounds very interesting! I hope you manage the soonest.
Why do you so deny the true face of the bussiness? Maybe we'll see "Engineered in USA" sticker on Evils in few years like we've seen on some big names.
quck Dave....apply for a patent for a spinning bash guard. That way when you hit rocks, it spins on the crank and the crank stays where it is...thus decreasing drag on the bike during impacts and keeping feedback to the rider through the cranks to a minimum...do it....DO IT!!!!
edit: Call it Spilt Bash-it!!!
edit: Call it Spilt Bash-it!!!
Better build it with a 1.66 gear induction so that it builds forward motion when it hits something call it the Hammersplit.
im not denying the fact what so ever. i understand why its made there and its obvious why as well.
wouldnt it make you feel all warm inside if it said "made in Slovakia" (does slovakia even make anything)
Yes, it definitely would make me feel warm if Porsche Cayenne, VW Touareg, Audi Q7 had stickers "Made in Slovakia" and not "Made in Germany" because they ARE made in Slovakia.
haha that reminds me of these...
maybe he can make some chrome spinning bash guards to go along with the new ridiculous TLD gear.
some of the hottest women in the world are made in slovakia. czech girls get all the hype, but i've been to both countries, and i think slovak girls might be better!
Hey men, we're getting little bit off topic 
, aren't we. But I do love Slovak girls, too .
, aren't we. But I do love Slovak girls, too .
ha-ha. I want a job working at the factory they are made in.
Didn't notice your location at first.Hey men, we're getting little bit off topic
My family is from Pavlik Mills...
To keep it on topic, I'd like to ride a Split-Pivot bike in Slovakia!
Teaser...
Seriously..I like the look of that front end.

So are Spooky Bikes the only one to introduce new SplitPivot bike ? And I had so many hopes for this year Eurobike ....
