Formula Introduces A New Technology for Air Suspension

Apr 4, 2018
by Formula  

Formula's latest trick is a special air-volume spacer made from a secret closed-cell foam material that, reportedly, alters the spring rate of a air-sprung fork to better emulate the linear compression and return rates of coil springs. Conventional plastic volume spacers can only control end-stroke ramp-up, which allows tuners to run slightly lower starting pressures, or increase suspension sag while reducing or eliminating bottom-out events. Formula's "Neopos" inserts promise that, and more.

The pink cylinders are compressible which, according to reason and the graphs in the following press release, create a more moderate spring curve through the more critical mid-stroke of the suspension, and soften the parabolic spike that conventional volume spacers create at the end stroke. In essence, the foam insert does not compress at the same rate as the surrounding air. The secret to moderating the spring curve is due to the lag created by the Neopos as it shrinks and expands during the compression and rebound phases. If Formula's volume spacers deliver as promised, they could be used to boost the performance of any number of air-sprung forks.

Formula press release




There's something new in the air.

Neopos is a technology that represents the next evolutionary step in air suspension - a cutting-edge innovation that will change your riding experience for the better. Neopos stands for “new positive,” a technology that improves the behavior of the fork’s positive air chamber. In R&D since 2011, Neopos will allow your air fork to reach a level of comfort, response and predictability unimaginable before this time.

Every great innovation must also be simple to use. The Neopos system has been developed with this in mind, and this new evolutionary stage of air suspension is now available to all riders.



A more linear curve, using all the available travel.

Neopos is not simply a volume spacer, rather, the Neopos completely changes the concept of a volume spacer. Thanks to the fact that it can be compressed, the Neopos makes it possible to make the air fork’s progression curve more linear, thus avoiding the excessive progressivity given by the traditional volume spacers, without giving up the much-needed support in the middle of the travel. With the Neopos spacer, you get all the support of a traditional volume spacer halfway through the travel, but without the abrupt ramp in the final part of the compression curve. The progression curve will always remain gradual, allowing you to use all the available travel of your fork.



A gradual and optimal increase of the air pressure level.

Thanks to its physical and mechanical characteristics, the Neopos allows for results that, until today, were unthinkable for air suspensions. While the fork is working, the Neopos inside the positive chamber will compress, thus allowing a gradual and optimal increase of the air pressure level. A result that can not be achieved with a traditional air suspension or with an air suspension that uses rigid volume spacers.





The response of a traditional air suspension is not constant.

The Neopos is not simply a “more effective” volume spacer. In fact, the heart of Neopos technology makes it something completely new. The progression curve of an air suspension is not independent of compression speed. As the compression speed changes, the air also varies in its response. In a riding situation, where the compression speeds change continuously, the response of a traditional air suspension will, therefore, neither be constant over time or 100% predictable. Simply put, it will be perceived as being more nervous than a coil spring.



A coil spring's response is always predictable.

In a coil spring, the situation is completely different. In fact, the coil spring always gives the same response to the same applied force, and it is completely independent of the compression speed. This results in the overall feeling of comfort and safety that a coil spring suspension usually forwards to the rider. The coil spring, being always constant in the response, makes the suspension more predictable, transferring a greater sense of control to the rider.



Neopos’ expansion time is always constant over time.

The physical characteristic of the Neopos is that of a slow expansion time which is always constant, i.e. it is independent of the compression speed. No matter how fast the Neopos compress, the expansion time will always be constant over time. If the suspension is subjected to a high compression speed, the Neopos will compress quickly but will still expand slower than the compression speed. For this reason, the real advantages of the Neopos technology can be appreciated on graphs showing the entire compression/extension work cycle of a suspension.



In a coil spring, the force returned is always constant.

In a coil spring, the force returned by the suspension to the rider (both in compression and in extension) is always constant, because it does not depend on the frequencies to which the suspension is subjected.
At the frequencies to which normally a suspension is subjected, a compression/extension cycle of a coil spring at the same load, will be the same both at high speeds and at low speeds.



With Neopos, the response of an air suspension tend to be more constant.

In an air suspension, with or without a volume spacer, the force returned to the rider, both in compression and in extension, is not constant because it depends on the frequencies to which normally a suspension is subjected. Thanks to the operation of the Neopos, the response of the suspension it will tend to be more constant.

The consequence is that the Neopos tends to make the compression/extension cycle more independent of the frequencies of the suspension while working which, in a riding situation, vary continuously. The result will be a more constant, predictable and comfortable air suspension. Meaning, more like that of a coil spring suspension's comfort.



Inserting the Neopos in your Formula fork is very simple, just follow these steps.

Removal procedure

Compatible with all Formula 35mm air forks.

The Neopos can be used with all Formula air forks with a stanchion diameter of 35mm (Selva, Nero R, Thirty-Five). A maximum of 3 Neopos can be used, regardless of fork travel.

As of May 2018, all Nero R forks will be supplied with two Neopos in the positive chamber. Since the 3Air System of the Nero R allows customizing the progression curve in the smallest detail, it will not be necessary to add or remove Neopos in this fork. In the Nero R, the Neopos has the function of making the response of the air suspension more comfortable.


Neopos Details:

Set of 3 Neopos
Suggested retail price: € 29,00 | $ 36,00
Availability: IMMEDIATE


Neopos is a technology that will forever change the way you look at an air suspension. A simple innovation, but at the same time, revolutionary. The feeling and comfort of a coil spring suspension but with the possibility of customization along with the lightness of an air suspension.

 You could always have stored wine in your stanchion. However, due to the air tight seals it won't be able to breath and thus won't age well. You're better off just using the stanchion to drink out of.

 @aljoburr: Looks like it free-floats in the formula as well - if the inside diameters are similar it will likely be OK. Would also mean that a larger diameter fork would probably not be a problem
  • + 1
 @sherbet: Also - Formula only appears to make 35mm and 33mm forks, so specifying "only works on 35mm" makes sense given that their lineup doesnt contain anything larger. I expect the issue is that if the fork diameter is too small it sticks, if it is a bit too large it probably has little to no impact.

 What is the obsession with linear spring rates?! The best system out there is Manitou w/ IRT so I can ramp that shit up.
  • + 3
 @LaXcarp: tbh, coil brings up much more than linear spring rate.. the initial forces needed without the complications of negative air chamber, the rebound behavior (even after near or total bottom outs), the midstroke support and recovery... you need to ride them a fair lot to notice it.. your rear suspension needs to be re-set after changing to a coil fork..
  • - 1
 @Lagr1980: Yea not buying it. 1. check out Manitou new air seals. Really only makes a difference in the parking lot and not enough platform to push off for technical moves. 2. Rebound is independent of compression. 3. feedback I get from coil is the support isn't there, ride a multi-chambered air spring and you can tune infinitely through the whole curve. 4. rear suspension needs to be reset for any fork changes, including air
  • + 3
 @LaXcarp: are you confusing IRT with the IVA volume spacers? IRT is specifically designed to give lower initial spring rate and more mid-stroke support without changing the final spring rate. if you just want more ramp up, the IVA spacers do exactly that.

 @xeren: No im not confusing the two. They are designed to have whatever rate you want in them, as long as you maintain a 10psi difference. Most people take that as an opportunity to lower the initial stroke psi but not blow through their travel by maintaining pressure in the IRT. I took it to further ramp up my end stroke (from mid-end) in a more specific manner than IVA can, while maintaining my initial rate. I run 55/90psi.

 I have a Selva on a bike, and a Pike on another. In the past year I have ridden Fox 36, 34 and DVO Diamond and I decided to go with the Selva. Compare to the Pike, it is just another level. It is way better on everything. Maybe the 36 has similar performance. The initial travel is coil, similar to the DVO. It is way smoother the than the DVO. Feels more agile and more playful than the other forks. Finishing is better than all the other forks. Service is easier than all other forks. If feels like the perfect mix between coil and air and you have total control over the travel and the settings. The bad part is trying to contact them on the site or US phone number. Do not bother. If you need to get an hold of them, just send a message on FB and they reply right away.

What do you think is the reason for RS, to improve the internal friction on the 2019 Lyrik?
They try to reach the performance of the Formula forks - because you can't find friction or even stick-slip there!
It works soooo smooth and the damping is excellent.

 So do these "float" inside the air spring? As in...do they rattle or deteriorate over time?

 I actually tried this about 6 months ago inside my Boxxer WC. Not these same ones, but instead I 3d printed some of my own bottomless tokens from a rubbery type plastic. The goal was to test a difference between the stock hard plastic, and one that could compress as the pressure increased through the travel. The difference wasn't huge, but I for sure felt a difference that I actually preferred over the stock tokens. Just seems to have less of a harsh ramp up at the end compared to stock tokens.

 Did you guys even read the article? These are hardly urethane elastomers. Developing a polymer foam with these precise pressure response characteristics is actually an engineering challenge. Having an air sprung fork or shock react the way a coil and oil shock does, but with the weight advantage and on the fly spring pressure adjustment that air allows is like the suspension holy grail.

 @Stylexxx: its much less in terms of the cost of material. the hard part of a fork is to get the crowns to hold the stanchions in line with the lowers. few fork company will tell you how well they did this.

 @Formula What is the typical time scale for the Neopos to expand back to its pre-compression state (say, assuming the fork is immediately returned to an uncompressed position)?

"Hi ******, thx a lot for your message. The Neopos has been developed to work with air forks, lubrication oil is no problem at all and there's not a single thing that can go wrong. We spent more then 5 years for developing. This said, we highly suggest to use the Neopos with Formula's forks, which are the best forks out there by the way ????. Cheers, Formula staff."

"That means that we do not have responsability if you use the Neopos with other forks than Formula's."

"To buy it you can go to our dealer locator or distributor locator on our website

 I think people are having a hard time understanding that these are not springs. They are just a compressible material to change the rate at which air compresses. This is actually a really cool idea. I would like to see some units on those graphs however.

 @RichardCunningham: This looks suspiciously like the guts of my old RockShox Quad21 R from the 90s. They didn't work worth a crap when it got cold because they just turned into a block of hard rubber. Is this temperature sensitive?

 @bbeak: I would argue they didn't work worth a crap when it was warm either
  • + 6
 @RichardCunningham: Arguably most people won't need more than 2 tries to get to their preferred spring rate and a mass produced coil spring could be sold for 20 dollars if there's no branding or shit on it.

Nothing against the air spring itself, but it's not reasonable for it to dominate the market to a degree it does. MZ 380 with coil spring needle bearing on my DH bike, no pumping every day and perfect reliability, even after a long time without service. I think the coil spring actually would be the better choice for most people. A bit heavier, but a lot more reliable, better performing and cheaper than air.

 @RichardCunningham: Richard if you are aftermarket hunting, for my is a no brainer to get a coil fork. brands like MRP and DVO (you can actually service them) are winners in my book.

 @PHeller: wrong, a French company (CR Conception) offers a coil spring conversion kit costing around 100€, 100% made in France, and that usually match the weight of the air spring system if not save some weight (on Boxxers I believe).

 I ended up with a Formula 35 fork recently (bought on a used bike) and it is seriously IMPRESSIVE. Took a while to tune in, but it's like a Pike but with even less stiction. It's the most active fork I've ever owned, in a very good way.

However I have yet to find a source for small parts... their italian support told me they've pulled out of the US. I'd love to hear otherwise!

 If these will work in an RS fork, it would interesting to play with mixing RS tokens with one of these. I keep moving between 1 or 2 tokens depending on where I'm rising that day, but could one token with one of these being sort of that middle ground I've been looking for...

 Perhaps I am way too open-minded, but rather than judging a possible effective new innovation just by a press release only, I would like to read a review on if, and if yes, how it changed a fork's characteristics and performance. @RichardCunningham, are you planning a review any time soon? By the way, keep up the good work.

 Manitou had the exact same thing 10 years ago (noble air spring had compressible volume spacers) ... My guess is in 10 more years, fox will release this tech and everyone will think it's a huge jump forwards
  • + 2
 As always, there are a bunch of misconceptions flying around in the comments. The biggest I see is that people think the insert IS the spring. Air is still the spring, the foam insert simply makes the air volume dynamic (changes depending on conditions). As the pressure increases, the spacer volume decreases, and ultimately the air chamber volume increases. How much of this is happening? I don't know. It's clear from the graphs that the foam compresses very little until near the end of the stroke. The other thing to factor in is that less spacer you run, the less of the volume reduction you will see. I saw a few comments about how the charts have no numbers, and that is definitely a good point. I think the numbers were omitted because those charts apply only to formula forks with this particular spacer. However, if you put them in another fork, the ratio of overall volume to spacer volume will factor in.

I really do think this is a somewhat valid idea, but the cost of that seems outrageous! I just looked online and.....

 I should also add that although this material APPEARS similar, I don't know how the chemical and physical properties/characteristics compare. I'm simply saying that foam is pretty cheap.
  • + 1
 @mtbsam: Right. Foam is cheap, but determining density, chemical/heat resistance and any number of other factors is pretty difficult. We won't know that stuff until they are out in the real world being anaylze by other manufacturers hoping to capitalize on the idea. If they work, give it a year or so before you see copies. I'm actually surprised Fox and RS don't make tokens that clip together but also can compress...
  • + 1
 Why not just make another air chamber at the top of the uppers where the spacers go with its own piston and chamber. then you can add air to that chamber and boom! There you go! Now you can ajust the progressiveness to whatever you want.



you just watch! this is going to be the next new fork design!!

 @southoftheborder: formula nero dh fork has 3 air chambers with 3 valves but I'd say it is fairly complicated to produce. Manitou dorado air automatically sets negative chamber pressure so you lose that adjustability. This actually seems like a simple and cheap solution...
  • + 1
 Stiction on the piston seal, adds heat to the fork, diffrent rebound rate , servicing. Would interfere with the air spring cap so would have to come up with another way to pimp up the fork.
I like this idea simple and effective. Its going to do what it says, even if I can't feel it cuz I'm s#@t.

  • + 1
 I wanted to LOL when I saw this, but maybe there's something here? For the foam to be compressed by air pressure enough to affect the fork curve, the pressure in the air chamber on a bit hit would have to be super-high...

Formula has about 0.001% of the fork market share, so for this to be widely adopted, it has to be licensed to other fork makers.

  • + 1
 As I see it there are many things with which to take issue. Graphs without numbers and such. What I noticed was the expansion time. Would the advantages (real of perceived) diminish after multiple hits. This would be far worse than the fade or change of fork compression due to heat increase or altitude change (yes a fork is a sealed system that should not change related to altitude change). Does any body else see this.
  • + 1
 Funny, I had this exact idea a few months back and even tried it out with a priority in a Fox 36. In the end it was just swatted to one side and I accepted that the awk double chamber idea was better. But maybe this is a cheap option, slightly better than hard plastics?
  • + 1
 Personally, I do not like compression curves at all. At the same pressure with traditional tokens the curve with the Neopos is much less progressive towards the bottom stroke. To reach the curve levels with the tokens it is necessary to increase the pressure by having a curve more linear than the one with the tokens but with larger initial detachment loads, going to lose the initial sensitivity of a classical compression curve. Forgive me for my English, please.
  • + 1
 I had a nice testride with that ...whatever you name it.
What can i say: INSANE!
Works absolutely brilliant. I run the same oil volume and the same pressure. Just added one of those... whatever. While using the same travel, there is clearly more support in the middle of the stroke. The fork just stays higher, the sensitveness and comfort remains unchanged.
Maybe i'll give another half one a try - they can be cut easily - but for now, i'm super happy with that fork, that was great already. Thank you Formula! Great job!

 This New POS ( translated from the Eye talian) is a recyclers dream. Now anyone can tune their suspension easily and cheaply. Just uncork and fit. Need another? Just down another bottle of cheap wine and use the synthetic cork to reduce the volume. Being drunk will add to the sense of front end compliance and ensure you never ride with a rigid fork...

 To say that an air spring's return rate behaviour is dependent on compression speed seems to be contrary to one of Newton's laws of physics. The one about for every action there is an equal and opposite reaction.

 One of the big issues with elastomers in the past was they turned to brick at cold temperatures. Did these guys give any info on how this stuff works in the cold? or does their perf change as they get really hot on long descents?

 Elastomers were rubber or variations on it. These are closed cell foam, which while they may attribute some compression changes in various temps, shouldn't be drastically different (unless the can somehow absorb moisture or oil in the air spring.)
