Well Got my first shot on the 2 stage bike that Glen Hayden rides and i gotta admit its a sweet bike it grips real good and is the quietest bike i have ever ridden.
Anyone else tried one?

Ha Ha you no me to well Damo,how you 2 keeping? im saving up to go to NZ at the mo so i cant buy one but i think i will i may in the future.No Dave, you can't have another bike.
That's a really cool idea, would love to hear more about it. But I think it could also be done with a single shock ala the Sinister Passion (a proto was being shown a lot last year, hasn't made it into production yet, but FTW said he has more R&D he wants to do to it). Anyways, it uses basically a doubled up linkage, but the lower has a bottom out stopper/bumper thing so that the suspension will work one way for small trail chatter, but once you go through this the lower linkage will lock out and the suspension will perform differently for larger impacts. Don't know how it would affect the axle path since that it what your friend is looking at, but it would be a lighter execution than a dual shock setup, unless he is designing the suspension around the performance of 2 shocks.Have a friend who thinks 2 shocks will allow him to make a frame that will have a rearward travell when needed and at the sime it will shorten in turns like a low sp. Haven't though about his idea so don't bash me if it's bs but not the first time I heard sb purpose sth like this.
Seems like a step up in susp desing. Would be nice to try it out. Damn I need to stop visiting RM as I'm more and more confused about the bike I want, at least as long as money is an issue for meThat's a really cool idea, would love to hear more about it.

Here's a link to the thread about the passion:

edit:
here's some better pics of the linkage, kinda dark but that big red knob is what stops the lower linkage:

edit 2: some more pics of the linkage can be found on pg 10 of the first thread I linked to.

I'd love to ride one too! I remember seeing the proto at Plattekill 2 years ago, then it showed up at interbike. Then there was some shuffling at Sinister, and I seem to recall that Frank decided that the bike wasn't ready for production and needed more R&D. That was the last I heard of it.Seems like a step up in susp desing. Would be nice to try it out.

Dude two short stroke air shocks weigh less than the equivalent long stroke coil shock! The problem with the Gemini was its execution, the second shock kept activating every time you hit the brakes, the idea was sound.I've always been fascinated by the dual shock setup, however the problem it always induces is substantial extra weight. Even Cannondale was experimenting with this when the Gemini was in its early prototype stages.
With the advances in shock technology the last few years, do the benefits of 2 shocks still tip the scales in favor of this execution over the downfall of the additional weight? Idk. I'd love to try one and find out.
One word: Titanium. And the differance between 2 airs and 1 coil is very small. Also you didn't think about the extra weight because of the extra bearings and linkage.Dude two short stroke air shocks weigh less than the equivalent long stroke coil shock!
That doesn't take into account the additional mountain hardware and linkage to fully and properly utilize them. Also, I suspect that one of the reasons for using both a coil and an air shock is to utilize the performance of both.Dude two short stroke air shocks weigh less than the equivalent long stroke coil shock!
Wasn't trying to knock the idea, only give an example of one of the major companies exploring a dual shock system.The problem with the Gemini was its execution, the second shock kept activating every time you hit the brakes, the idea was sound.
True, but in the case of the 2stage, the shocks share the same mounting hardware of the link, and there is only 1 link, hardly adding weight and complexity. Its just a single pivot on top of a single pivot? Cannondale would have had their reasons for using a coil and an air shock I guess.

They are all different so calling it a single merit would be wrong. 2 shocks just give more room to play. I've already seen 4 different applications of using 2 shocks.Yeah, there seems to be a few more coming out of the woodwork now too! Maybe there is some merit to it?

Yup, you are right, they are all different, I guess I was refering to bikes with more than one axle path or a travel area, and yeah, not all 2 shock bikes have this feature.They are all different so calling it a single merit would be wrong. 2 shocks just give more room to play.

Can you be more specific?Is it really the case with 2stage? Tech monkeys gave mixed answers about that so I'm confused about it.
Is really 2stage a bike with area of travel instead of one axle path?Can you be more specific?

Yes, it is an area of travel. It does look like you may get some pedal kickback on big hits, but it shouldn't be too bad with the pulley placement they're using.Is really 2stage a bike with area of travel instead of one axle path?
Check out the animation on the home page of their website or go here http://www.2stagebikes.com/cs/services.asp?type=18 It's basically two axle paths with a smooth transition in between.Is really 2stage a bike with area of travel instead of one axle path?
Rankin apparently hated his tho', but meh, buddy I know who had one loved it so...Guys why don't you check out the tech on there website, they've won 2 DH campionships in NZ that I know of 1st an 2nd in fisrt year of production, though those guy's probably would have won well on any bike, its well thought of here, not my type of bike I'd have to ride one to be swayed, Ive see enough of one in my local area goes well and even better now that its been tuned up!
There's plenty of tech and visuals on here to get ya tech heads for or against it!
