Click on it - Very Interesting! Could this be the holy grail for MTBs? A shock that's super light but (seemingly) unaffected by heat build up. . .

arent nitrogen filled shocks unaffected by moisture and heat?
pure nitrogen is much more stable than pure oxygen (highly flammable) but it is still affected by heat. Pure nitrogen is also moisture-free. Most bicycle shocks are pumped up with a hand pump which is just drawing in atmosphere, which contains a good amount of nitrogen, oxygen and moisture. Although pure nitrogen is better than atmosphere or pure oxygen as far as resisting fade and preventing moisture damage it is still affected by heat.

So would it be possible to get a DHX air filled with nitrogen?

I can see the 4 page argument over nitrogen already.

Back on topic, I'd rock it. Lets get some e-speculation on sizing and stuff.

Livin it up in the O.C.
I like the little Shout-out to GarageWorks in the Bikemag article.
Most people know all about Push, but not GW. Steve (the owner) of GW has been working on MTB shocks since their inception and can do amazing things as far as custom tuning. Probably why he is one of the official shops for 5th element.

of the 21st century he meant i think.
Well, I wrote that the "MAGURA MX" were "... the first air shock with air dampening for MTBs ..." that is "...based on an approved technology they bought from CONTINENTAL Automotive." One of the important new things of the CONTINENTAL technology is the flexible rubber bellow that works together with the specific roll-of cone (http://fotos.mtb-news.de/img/photos/7/0/0/5/_/large/img_2006_10_10_Intermot_cads_2_en.jpeg). The "classic" air shocks by CANE CREEK ("Cloud Nine", "AD-12", "AD-5" http://www.canecreek.com/shocks.html), EKO SPORT, Inc. (ENGLUND "Total Air" http://www.mountainracingproducts.com/ta_notice.html, http://www.mtbr.com/reviews/olderfrontshock/product_21453.shtml, http://dirtragmag.com/print/article.php?ID=573&category=departments) as well as of Patrizio BERGAMELLI ("BERGMAN" Forks from Italy http://www.pro-mstore.com/prodotti.ctr?idcat=18&id_cat=75) are of course well known to me.

I'm guessing you're quite well informed for a reason Wilhelm; so I'm going to try a few questions:-

Adjustability - 1,2,3 or 4 way adjustable? Is low/high speed catered for and if so can it be adjusted individually and separately?

Make Up - What is that bellows made of? It must be at some pretty high pressures and is extremely exposed.

Travel - Is the design limited to a certain stroke length - for instance would the bellows diameter get relatively too big on a 3" stroke?

I'd be interested to hear some answers if you know them or if you're allowed to say if you do. . .

motorcycle shops have nitrogen tanks on hand and Costco also has it to fill car tires with. But like someone said there will still be some contaminated atmosphere left in there unless you disassemble and reassemble in a clean environment.

@SPDR,
all my "knowledge" about the MAGURA "MX" shocks is acquired from the above-mentioned articles in web based journals as well as forum discussions (http://www.ridemonkey.com/forums/showpost.php?p=2794568&postcount=1). The only official informations of MAGURA are to be read in their flyer (http://www.singletrackworld.com/docs/mx_rearshock_english.pdf?PHPSESSID=94166971760022ac2fb1dc645f68b03a). So far as I know there are the parameters of air pressure as well as of rebound that are adjustable only. One of the main goals of this shock technology should have been simplicity (including adjustability) and low maintenance. I desire but don´t believe that they´ll come out with a model that has a nice 4-way adjustability. In one of the pics (http://www.singletrackworld.com/article.php?sid=2669) it seems to me that there may be the option of a lock-out. Back in 2003 there was to be read in an article of the news magazine "bike sport news" (http://www.bike-sport-news.de/modules.php?name=News&file=article&sid=4159, unfortunately in German only) about the CONTINENTAL "Airbox" prototype that it would consist of 3 air chambers. However, I think that a "marriage" of the ÖHLINS "Twin Tube" technology (http://www.ohlins.com/Automotive/InsideTTXContainerPage/TTXIntroduction/tabid/131/Default.aspx) of the CANE CREEK "Double Barrel" shock (http://www.canecreek.com/double-barrel.html) with the CONTINENTAL "bellow over roll-of cone" air shock technology by MAGURA with all the options of the independent 4-way adjustability would be fine. Unfortunately, I don´t know what the bellows of the MAGURA "MX" shocks are made of. I would like to know if there are limitations to the stroke length, too. At least, it would be nice to see a DH/FR capable 3" stroke variant of the "MX" shock.
However, I´m wondering why MAGURA didn´t show the "MX" shock neither at Eurobike 2007 nor at Interbike 2007.

I guess I don't get how it's impervious to heat. The energy from damping has to go somewhere and air doesn't have much heat capacity... I would expect huge increases in pressure under sustained use.
