Review: Formula Neopos Air Volume Spacers

Nov 8, 2018
by Paul Aston  
Formula NeoPos


Formula's Neopos air-volume spacers are a foam version of the solid plastic tokens we are used to finding in most air-sprung suspension nowadays. For those out of the loop, adding or removing "tokens" or spacers from a fork's (or shock's) air spring is a method to tune the spring curve and the ride feel by altering the volume of air in the spring chamber. Neopos foam cylinders are made from a 'secret closed-cell foam material' that are said to give your fork a more consistent compression stroke, and get it closer to having that sacred 'coil-like feel.' A pack of three Neopos costs €29 EUR / $36 USD.

Installation & Theory

Previously, Formula didn't offer a plastic token option for their forks. Instead, it was recommended to add between 5cc to 35cc of oil to the main air chamber, which is effectively the same as adding plastic spacers, but with the benefit of infinite adjustment to the spring's volume.

Installation of the Neopos couldn't be easier – just remove the top cap from your Formula fork's air spring side (deflating the air pressure first) and throw them in – they do not need to be screwed or clipped to anything, they can roam free. Neopos are a much easier solution than adding oil to the fork, which was a faff to add, drain, and measure each time you wanted to make an adjustment.

Formula says that only one Neopos is needed to give its claimed benefits of a more linear feel, putting in more than one will not make it any more linear. Adding more than one will continue to increase mid- to end-stroke pressure, the same reason you'd add more plastic spacers.

You can read Formula's press release here for all of their science and graphs, but here is the layman's description: The initial stroke of the fork will feel the same at the same air pressure, mid-stroke support will be increased slightly, but the main difference will be less ramp up towards the end of the stroke. This is because, as the foam compresses, its volume reduces, which gives a more linear curve to the air spring, closer to a single rate coil spring which is perfectly linear.
Formula 35
The Formula 35 fork's air spring was originally tuned by displacing its volume with a measured amount of oil.

Speed-Sensitive Air Spring

The second claim is that, because Neopos' slow-memory foam compresses at a measured rate, the volume it displaces changes with the speed that the fork is compressing the air spring. For example: If you compress a fork to bottom out slowly, the max pressure could be 300psi, because the Neopos has time to compress at the same rate of the surrounding atmosphere. But, if you compress it very fast, the Neopos will not compress completely, the air-spring's volume will be reduced and the bottom-out pressure could be as high as 380psi.

Neopos' speed-sensitive action also controls the high-speed rebound rate. Because the bottom out pressure is higher at faster shaft speeds, the rebound speed is correspondingly faster. If the fork is held near full bottom-out, however (say, in a G-out situation), the Nopos will continue to shrink as it adjusts to the ambient pressure in the air spring, which will reduce the internal pressure to that original 300psi, thus slowing the rebound speed significantly. The result of using Neopos is a more consistent feel in both compression and rebound over a much wider range of impacts and speeds and, in theory, allow the rider to use all of the fork's travel, while retaining mid-stroke support, and without continuously bottoming.

This graph shows how the Neopos affects the spring curve. The two most important lines are the two middle lines at 60psi with a solid volume spacer vs. Neopos. We can see how the beginning and mid-stroke are the same, but there is a difference at the end of the stroke as a solid token will ramp up much more as air volume inside the decreases rapidly.

Riding the Neopos

Does it work as claimed? "Yes," is the short answer, I have tested the Neopos for months in different situations, but this describes one test ride: I found a short section of super rough trail in Finale (not a difficult task) with some corners and rocky straights. Starting with 10cc of oil (the equivalent of one volume spacer), I did a few laps to get a feeling for the Selva fork. Previously, my fork settings had felt over-damped and I wasn't getting full travel under any circumstances.

Out with the oil and in with the Neopos. I started with one. A few more laps revealed that there was a slight increase in mid-stroke support, which was easy to feel. More difficult to tell was if there was a benefit in the repeated and rougher big hits. It was hard to put my finger on, as the sections were rowdy, so I was more focused on the trail features. That said, there appeared to be an increased calmness to the fork in at the times where I was gritting my teeth and holding on the hardest.

Back to the workshop, I added one more Neopos and then headed back up. The fork retained its sensitivity (the Selva fork is one of the smoothest out there), and there was a more noticeable increase in the mid-stroke support. Now, however, the Selva was slightly harsh towards the end of the travel. The culprit, I discovered, was the Formula's 'e-bike' CTS (Compression Tuning System) chip I had previously installed in an attempt to increase the mid-stroke support of the fork. With the increased support from the Neopos, it was unnecessary. I switched it out to the original, 'Special Soft' CTS chip and the fork was spot on.

A few more laps determined my fork was working better overall, with more mid-stroke support and less ramp-up towards the end stroke. The lighter tune from the softer CTS gave me better tracking, bump absorption and less feedback into my arms and hands. Better still, the O-ring on the stanchion tube proved that I was getting full travel.

Starling Murmur Review Formula Selva

So I can put the Neopos in any fork, right?

No. The Neopos are not designed to work with non-Formula forks. For this reason, the official position of Formula is the following: "Neopos is designed and engineered to be compatible exclusively with Formula 35 and 33 mm stanchions diameter air forks. Formula is not responsible for any improper use of the Neopos on non-Formula forks." But, for the sake of our loyal commenters who would have instantly posed the question, and because I have heard of riders on the World Cup circuit using them in other brand's forks (even chopping them up to fit inside shocks), I decided to see what would happen.

The first great (and remember, not recommended) benefit of the Neopos is that they can be popped into any fork, and coming from a guy who has a drawer full of colored tokens - but never the right one - this promised to be a great problem solver. The next experiment was to try the Neopos in a 2017 RockShox Lyrik fork, swapping three tokens for two Neopos. I found a similar improvement, with increased mid-stroke support, although the Lyrik is already more linear than the Selva, so it didn't have as harsh an end-stroke feeling as I had to start with my original setup on the Formula fork.

Neopos degradation
Neopos degradation
My Neopos appeared to be degrading after a few months use in non-Formula products. Some mechanics who have done the same reported finding chunks of foam blocking the positive/negative transfer ports.

The third fork that the Neopos spent some time in was a Fox 36 on a Mondraker Level eMTB. After numerous days on this bike, the Neopos started to show signs of degradation, with lots of small pieces of foam inside the fork's main air chamber. This has not caused any problems for me so far, but I have heard reports from some World Cup mechanics that the small pieces of foam can work their way into the tiny air transfer ports that allow flow between the positive and negative chambers, which could affect fork performance. The takeaway is, use Neopos in non-recommended forks at your own risk. I wouldn't want to strip and clean my fork just to remove a bunch of foam particles.


Conclusion

To conclude, Neopos do perform as claimed in their Selva fork – a more linear spring curve and more predictable. For the €29 price tag, I would recommend that any Formula owners at least try the Neopos to see if they give the performance change they might be looking for. Another PB editor using Neopos exclusively in a Selva has had zero issues with degradation after well over 100 hours of use (more than Formula's suggested replacement interval).

The degradation I saw when I tried them in forbidden forks was likely caused by irregular-shaped air chambers or incompatible lubricants, so I do not recommend the use of the Neopos in other brand's forks. If I were a pro-racer with a mechanic or an avid suspension stripper, however, I would use them without a doubt.

Warning: Don't think that you can save yourself €30 and put in a chunk of your Mum's kitchen sponge and achieve the same thing.


Pinkbike's Take
bigquotesNeopos is a recommended solution for riders looking to tune the mid-stroke and end-stroke characteristics in their Formula fork. They are easy to install and live up to their improved performance claims.Paul Aston

 Been using the rubberised corks you get in wine bottles for a while now... They can be cut/shaved/drilled and (glued together) to stick into most top caps and so don't rattle around/break-up. Bonus is you get a free bottle of wine with each spacer you buy - marketeers are you listening?! ;-)

Real cork is better, but these are degrading soon, and tiny bits may block the air channels.

 Hold on, has no one noticed the throwaway comment at the end of the article?
"after well over 100 hours of use (more than Formula's suggested replacement interval)."
So $30 for something that is designed to be thrown away after less than 100 hours use. Way to go green formula...
  • + 12
 100 hours mountain biking time (actual ride time, not including all the faff at either end of the ride) will be more than a year for the vast majority of riders.

It is also about the recommended service interval for most forks. Most people ignore that too. www.sram.com/sites/default/files/techdocs/gen.0000000005593_sc2_service_interval_counter_mat_v10_eng_rev_b.pdf

The oil you chuck out at a service is a lot more damaging than a few grams of plastic in these.

 @Daver27: If you use even one disposable plastic bottle during those 100 hours of mountain biking either before, after or during you are going to be using a lot more plastic.

The question is what happens when you leave them in too long. If they degrade and the small particles start blocking stuff inside the air chamber, you could have a bigger problem.

 @kopaczus: Do you replace dust wipers and oil in your fork or shock? those are generally more than 30 bucks every 100 hours? what about grips? chains and derailleur pulleys? shift cables? brake pads? Pivot bearings? its silly that these should be replaced but I bet a mountain bike cost about 500 to 1000 bucks to run for 100 hours if you pay retail and do all the "recommended" service. That's why no one does it.
  • + 3
 @Patrick9-32: Are you seriously claiming that 'the vast majority of riders' ride less than 2 hours a week?
Are you also saying that whatever they do at oil disposal sites isn't actually the right way to get rid of oil?

 You get a pack of 4 of them when you buy them. In practice, I've found I only need one... I've got 100 hours on it in my Yari and it's exactly the same as when I bought it. So maybe I'll change it out at 150 hours... that means I've got 600 hours worth of them. I probably won't have this fork or even this bike for 600 hours.

 Technically, formula took the idea from Manitou who had a similar design a 10 years ago in there MRD forks. Noble air system if I recall correctly.

The thing is, Manitou's IRT air spring, and all the similar twin + chamber springs achieve everything these spacers do, while being infinitely adjustable to the users liking.

 @mullen119: plus they don't leave chunks of foam after a while for those of us without personal suspension strippers.

 @mullen119: Not true. Key here is the NEO-Pos occupies space in the air chamber and that space changes when the fork is compressed. Not the same thing. And by the way i've ridden few years on IRT system and love it.

When converting your air fork to coil you mostly cant convert back.

 @NotNamed: You could do that with MRP. I believe the issue is that once you go coil, the metal spring, even when protected, mars the inside of the stanchion too much so that it won't hold air properly if you go back.

 So, I have been using them for a few weeks now in my Lyric. Improvements as told, very very nice feel for the midstroke and less bottom-out resistance compared to two tokens.
Hard to say if ist worth 30€ but I really like the new feel of my forks!

First thing I will do tonight is take them out and check for any wear and tear. Maybe it would help to attatch them to the top cap and glue them together in any way...

 I put one in my sektor, made a big difference to me. As you describe and just 'better' in all situations, it's the consistency thing which is important I think, a more predictable feel, more like you would get with a coil.

It must work, or pro mechs wouldn't be wasting their time cutting them up to fit in shocks.

 @Brookes: I was thinking about this too but thought that since its as a material that will be compressed, I figured it glueing it wouldn't be an option as it would pull off as it shrinks, but if in the real world that doesn't matter, awesome. The solution i'd come up with in my head was taping a bit of string to to top cap, threading the string through the center of the neopos and tieing it off. It will stay in place up at the top of the top cap and there is nothing restricting its compression (liked i'd assumed the glued butt end would).

 I put 2 of these in a Pike last week. Great so far, will keep an eye out for degredation. Sliced 1 up and put it in my rear shock (ccdb air) to replace volume reducer bands, not so impressive. I think it's down to the higher pressures in a rear shock. By the time you pump it up to working pressure (150psi v 85psi for fork), they are already halfway compressed.

Manitou has a three chamber system called IRT available for the Mattoc trail fork, and chickadeehill makes their three chamber AWK spring kit for Rockshox forks down to 120mm of travel and for Fox forks down to 130. Clearly a three chamber air spring system can work for more than just downhill forks.

 @FuzzyL: my comment wasn’t sarcastic, I honestly don’t know if anyone who rides one.

 I do. Is excellent.

 @colincolin: Might be a North America vs Europe thing. MRP, Manitou, DVO, are all based in the USA. I've seen them all here. And Ohlins because they come on Specialized. I've never seen Formula forks, and in all my years maybe only one set of their brakes that came stock on a commencal.

 I have seen plenty of high end formula brakes on the trails. I do have the selva and it makes the pike look like a budget fork. You can get it from universal.

 @colincolin: MRP, Manitou and DVO are common enough in the Northeast...i have yet to see an Öhlins fork in the wild.
  • + 2
 @nyhc00: As an Italian Brand they might indeed be much mit common in Europe. Plus, as far as I know, they’re only spec’ed on bikes of rather small brands. But they’re reasonably priced for a fork that’s made in such relatively small batches, and they work really well, especially the supple feel is something I like, I wouldn’t be surprised if they became much more common.

 I have a pack of these for sale in the buy sell. Work as advertised, used them in a Rockshox Yari, but sold my bike and now have MRP with their ramp control. Look me up!

 Might want to give this a look Pinkbike, very similar to this and the Manitou IRT diazsuspensiondesign.com/runt

 IRT is excellent. This NeoPos is a different concept. Is a simple idea. Sadly, all the 'bigger' companies will copy it.

 That looks amazing! I've used the Luftkappe and MRP Ramp Control, but that sounds like a step up.

 I have one of these RUNTS from diazsuspensiondesign.com in my Fox 36. This thing is amazing!!! Not made out of a sponge, but rather engineered for different travels in different Rock Shox and Fox forks. It is infinitely adjustable. Makes the small bumps super plush, while maintaining mid stroke support and bottom out resistance. You CAN have it all. yeah it costs a little more than wine bottle corks,($200US) but it doesn't degrade and the only maintenance would be a 30 cent O ring every few seasons!! Well worth the money if you want to go faster, corner harder, and drop bigger!

 @paulaston Have you tried to glue it onto rs/fox original token or only onto its screwing base? That could work I guess

 So the Fox fluid is degrading the foam, So, can you run formula fluid in a fox (or RS) fork?
  • + 1
 Reminds me of the MCU's (microcellular urethane bumpers) back in the 90's than Manitou used which would hydro-lock when wet

 Hey Formula, how much does that socket to remove the top cap cost? Oh you don't remember? I'll tell you. It's 34 euro.

So when you quote 30 euro add another 34 euro for a non standard specialized tool.

 Have been running one of these in my Rockshox Yari since they came out. Works great with zero adverse affects.

 And paying 30 quid for these .I am going to the hardware shop and getting myself a can of expanding foam .Undo the top caps and squirt it in. Winner,Winner Chicken Diner

 My RS bottomless tokens have some squish to them. They are not made of hard plastic.

 This is actually true for the ones that go in the dual position forks, they are rubber and not hard plastic, but nowhere near as squishy as foam.

 Seriously, had flashbacks to the early nineties and disintegrating elastomers in my Manitou fork. This is the last thing I want to see when I wake up in the morning. Wink

 @Lotusoperandi: Theoretically, if it is closed cell foam, there should be no disintegration.
  • + 1
 @Poulsbojohnny: Absolutely correct! Neopos has nothing to compare with old elastomers. The elastomers don't even compress with air. Check this out www.facebook.com/rideformula/videos/2053761097985771. Cheers!

 Hi, Neopos is not to compare with old elastomers. Here a video you can maybe find interesting www.facebook.com/rideformula/videos/2053761097985771. Cheers!
