apparently we also have been doing it all wrong

That thing is uglier than my tax return this year.

 

[lobsterCT]

I read as far as I could in that review until my eyes crossed and I got a headache. Seemed big on claims with little real data. I would like to see the leverage curve.

I sense marketing bla bla.My linkage license is on my computer at home and I'm stuck at work.

But it seems like @andrextr commented at the bikerumor article already.

Just saw the videos. Dat main pivot placement and chain growth... what is the pedal kickback like on this polygon-shaped ugly fucker?

 

[Adventurous]

It looks like someone re-purposed a prosthetic arm for the swingarm.

 

[jonKranked]

i know someone who's already ridden it, according to him it's the real fucking deal.

here's some crazy shit:

In fact, Voss had to work closely with Fox to provide an X2 shock with almost no rebound and compression damping to optimize its performance. After testing, Polygon deemed the shock's platform lever unnecessary and eliminated it entirely.

 

[mrgto]

Looks flexy...

 

[captainspauldin]

Goddamn that thing is ugly.. "r3act 2fun" suspension, wtf? Is that a joke?

 

[slyfink]

they missed the boat. that design looks perfectly suited for a gearbox.

 

[dcamp29]

shock yoke longer than the shock

 

[jonKranked]

shock yoke longer than the shock

specialized is going to have a tantrum

 

[xy9ine]

i'm curious how / why the significantly reduced damping rates work (ie, talking about 60% reduction over "standard" tuning, and riding with both compression & rebound in fully open positions). what magic is going on?

 

[6thElement]

Black and red one on the bikerumour article looks pretty badass.

Reminds me of what a bike might look like if Picasso designed it. And I don't say that like it's a bad thing, it just looks like a cubist expression of a traditional bicycle to me.

both articles mention another company will be releasing bikes w/ this suspension in the near future. i'd also be willing to be that polygon has a DH version in the works too

 

[Jm_]

If you need a bike that doesn't benefit from the lateral stiffness of full rear triangle and has no space in the front triangle for anything, this might be a good bike for you.

Otherwise,

 

[blindboxx2334]

ele cs. do not want.

 

[Westy]

We just need the engineer to come here and be a complete dick about his design. Promote and defend it with unsubstantiated and unquantifiable claims.

 

[blindboxx2334]

the rear end reminds me of this:

 

[TrumbullHucker]

bongshed material... but i would give one a go hell ya

the pinkbike article hints at more stuff in the works, both from polygon and another company. wonder if we're gonna see anything at sea otter next week

 

[Sandwich]

it's not about the math and science behind the designs guys, it's about the feels. The feels make the ride reals. also about patent dodging using a tube instead of a link. and besides, who doesn't like more maintenance?

the level of gobbledygook marketing speak is on par with tantrum though. I wonder which one will hobby horse through a nice aggressive trail faster?

[canadmos]

Why bushings?

 

[jonKranked]

Why pressift?

better question

 

[norbar]

I'm seeing so many durability problems here jesus. I didn't read the article fully but how will this perform reasonably well with DHX 5.0 2007 levels of damping and why does it need so little of it?

Also paging @Vrock @Udi @hmcleay.

evidently we peons are simply incapable of comprehending the complexities of the system:

naild-it (3 hours ago)
i was lucky enough to be part of the press-camp ...
think about it this way: antisquat/progressivity/leverage ratio graphs... these are all static and for-the-most-part two dimensional ...

the key to the design is the ability to balance both the rider's pedal input (graphs above) AND the inertia (acceleration or deceleration) of the rider ... yes it is dynamic and not easy to describe on paper or the web

the current tools of curves and ratios are insufficient to fully describe the design.

So what we have here is our first mormon bicycle?

If you believe it is the best bike ever, it is the best bike ever.

Why bushings?

why a series of tubes?

 

[jackalope]

Magicneering aside, what I am most concerned about is that they were apparently willing to let a Juggalo name (and spell) the suspension system, but did nothing with the fact there's a big black shaft moving in and out an orifice.

 

[troy]

There is no magic engineering behind this thing. The tube thing works like nothing else but a super long link that moves in a certain axis. It works like every other 4bar design. Those A-S and A-R values look fine to me. With some simple analysis (MOST LIKELY - without detailed drawing etc. ofc) it will have a simple flatish/slightly progressive LR combined with an air shock, soo I can't see really see why would it be the next best thing since sliced bread... With that AS curves it will pedal nicely tho, not sure about the pedal kickback values, but the uber high AS values especially at the end of the travel suggest nothing good.

The linkage is actually a quantum cage that captures magic that warps the time space continuum.

Well thanks for that Mr. Killjoy...now what in the hell are we going to talk about over the next few weeks before Lourdes

Sounds flexy.
