Tannus Introduces New Armour Tubeless Inserts

Aug 5, 2020
by Tannus Tires  
Downhill and freeride pro Reece Wallace explains the features of the new tubeless insert


Tannus has developed a tubeless insert to add to our Armour insert line, built for riders looking for the highest-performing tire and rim protection for their tubeless setups. Insights for the tubeless insert came from our original Armour insert, which uses tubes to give the insert its shape. The tubed version continues, with the tubeless insert giving a new option for more riders.

bigquotesThis is the hardest project we’ve ever done. The market for tubeless inserts has serious competition, so we had to design something that we believe is truly a better solution than those currently available. Youngki Lee, Head Engineer of Tannus Tires.

Armour’s winged shape is designed to provide a smooth but active ride feel that’s not overly damped

Armour Tubeless’ shape blends both an in-rim and free floating design, hooking into the rim bed while arching up and into the main chamber of the tire. Since the insert doesn’t need to sit flush against the rim, Armour is easy to install, with a five-minute average install time.

Ride Feel

Tannus athletes said one thing they didn’t like about other inserts was the “dead” feeling that thick shapes create, so our new Armour design acts more like a spring than a punching bag. It absorbs hits, but doesn’t eliminate trail feel. The tubeless Armour’s wings also give sidewall support for optimal cornering feel, while not overly stiffening sidewalls and impeding traction.

Material and Weight
Armour uses a new version of our proprietary Aither 1.1 foam technology and weighs 150 grams, lighter than many other premium tire inserts.Our development team took over two years to create a tough, impact absorbing and active substrate that can be molded into the desired shape while being light enough for downhill, all-mountain and trail riders alike.

Testing found that the tubeless Armour decreased rolling resistance and improved small bump compliance, making Armour three percent faster in the lab than a traditional tubeless system.

• 150 grams (equivalent to a tube)
• 5-minute installation
• $50 per insert
• Two sizes available: 27.5” x 2.1 - 2.6” & 29” x 2.1 - 2.6”
• 3% faster than tubeless in rolling resistance testing
• Winged structure for sidewall support and active ride feel
• Aither 1.1 proprietary foam technology
• Tannus Armour is available at www.tannusamerica.com.

 Would be interesting to test rolling resistance of various inserts. Does an insert that rides "higher" on the sidewall, like this one, chafe against the casing and cause rolling resistance?

I'm sure not everyone cares, but many do and this information is currently nonexistent.
  • 5 0
 I should add: I'm glad Tannus mentioned this in the press release, which is better than most. Still, would be nice to have some independent testing and see how others compare.

If Tannus can support the claim of improved rolling resistance, that would be impressive and opens up a whole new marketing angle for inserts.

 We have more information about an in depth rolling resistance test on our website (it should be there, if not I’ll have a chat with our IT guy ASAP). Put simply, there’s a reason we went with the shape that we did.

 @Tannus: I see the PDF on your website. It's light on information, says nothing about test methods, and does not cite the lab used. I'm not saying it's incorrect, just that it does almost nothing to support the claims.

Thank you for considering rolling resistance and I look forward to additional information.

 The point of these inserts is that you can run tires at lower pressure which throws the rolling resistance out the window, which really is useful for harder cornering like you would riding enduro or DH.

For trail/xc riding that isn't all about speed, you generally don't really need inserts, just run the tires at higher psi. Most of the 2.4-2.6 trail based tires at 30 psi are still plenty compliant. Hell, even tubeless is not really needed for most people out there that don't ride rocky stuff with high puncture resistance.
  • 4 0
 @onemind123: @onemind123: My guess is reduced rolling resistance could be achieved by holding constant the pinch-flat resistance, which allows lower pressure. Lower pressure usually reduces rolling resistance on rough terrain. Reduced rolling resistance on road or smooth terrain seems unlikely, but I'll try to keep an open mind.

I'm interested to see how Tannus presents their data and whether others will perform similar experiments. It would be an exciting development in bike design if we could simultaneously improve rolling resistance, pinch flat resistance, energy management, and tire stability.

This is all on our website now. Enjoy!
  • 8 1
 @Tannus: Thank you, that's a big step in the right direction and better data than we typically see from insert manufacturers.

Those are good numbers from a mid-weight insert. Some thoughts:

• Tire width could be wider. 2.3" is rather small; most people - especially those who like new technology - are using about 2.5".
• Pressure range could be tighter.

Rolling Resistance
• What was the roughness of the test drum for the rolling resistance test?
• It's difficult to understand how rolling resistance can be less with Armour Tubeless and CushCore than no insert. Impressive result if this stands up to further investigation.

• Inconsistent, non-linear responses warrant further investigation.
• How significant or problematic to riders are the observed vibrations and amplitudes?

Rim Off
• Seems like a reasonable test. Does it correspond strongly to observations during ride testing?

Shock Absorbtion
• A large difference is observed between the Tannus and CushCore vs. others. If this is due to the impactor “bottoming out” the other inserts and hitting the rim, it would be nice to compare the pressures at which this force spike begins to occur.
• It may be more analogous to real-world riding to increase the pressure of the other inserts until similar shock absorption values are observed and report the pressures required to achieve this.

Thanks again for the data. It appears you may have a superior product and it would be as useful to you as it would be interesting to me to further validate it via test data.

  • 2 0
 @R-M-R: I have been curious about some of these things as well. in particular, rolling resistance. One thing that I have thought about in regards to that could be the volume that the insert takes up leading to a ramp-up in pressure as the tire is pushed into the ground, similar to a volume spacer/token. Either that, or it could be the increased pressure on the sidewall of the tire, allowing the tire to retain a more rounded shape. If the tire retains a better, more rounded shape as it is compressed, it has a smaller contact patch which correlates to less rolling resistance. That is my theory at least. I would be interested in what actually contributes.
  • 3 0
 @whattheheel: Thanks! Glad other folks appreciate the nerding!

@downhillbrill: If the data are accurate, which I currently have no reason to dispute, the next two questions could be:

1. What makes it so? It seems reasonable that an insert chafing against the tire would cause friction and waste energy, but maybe other factors, such as those you suggest, dominate. It's certainly unexpected.
2. Does this effect hold true in real-world riding? Rolling resistance is difficult to accurately measure outside of a lab and we appear to be dealing with only a few percentage points.
  • 2 0
 @R-M-R: good point. What does 1-2 percent on a roller equate to on a track? Just looking at results from world champs last year the difference in times between 1st and 2nd place is 0.2 percent difference. The difference between being on the podium and watching the podium is 0.1 percent. I am also curious about what that lab percentage equates to on a track. But then there are the confounding variables like weight, traction, damping. Trying to get statistically significant data would require 1000s of downhill runs per individual rider. Sign me up for that. haha
  • 2 0
 @downhillbrill: XC could also be a good application. Many XC racers use tires with a little bit of puncture protection (ex. Maxxis EXO or Schwalbe Snakeskin casings). With an insert, maybe they could use tires without puncture protection, which would partially offset the weight of the insert, and they would have less rolling resistance from the faster tire and the (possibly) reduced rolling resistance with an insert.

 I’ve been running these for about 6 months now, and they’re pretty impressive. I still like to use a double down or equivalent tire out back, but I can run as low as 22 PSI before I get unwanted flex. This is pretty incredible, as I before I would run 28 up front and 30 out back. Tons more cornering and braking grip without tires folding over, significantly more comfort and less fatigue on long descents, crazy light, and not a pain to install. Highly, highly recommended!

 Would these help with tire squirm in hard corners? I like the way my bike feels at lower pressure for riding around but I get into some hard fast corners and it feels like the front tire is going to rip off. And sometimes it does..
  • 10 0
 Yep that’s the idea! So far we haven’t had any reports of anyone being able to rip a tire off, but I’m sure It’ll happen. I personally run 20 psi at places like Silver Mountain and Moab and have yet to roll a tire or have it feel squirmy.

 20! Wow if I creep below 30 I’m destined for some burps. Thanks for the quick reply. I @Tannus:
  • 1 0
 @Tannus: can you explain how this design helps prevent burping or tyres folding? The majority of the material is in the widest bit of the tyre, and the "legs" down by the rim surely can't do a lot to prevent burping. Having recently fitted a Rimpact (breaking 2 tyre levers on the process), it's clear how that supports the bead. But I can't see how this does.
  • 4 0
 @mountainsofsussex: Great question. The insert itself is much wider and flatter than the pictures do a justice, so it's folding a decent amount in the middle after it's installed. What happens is the outside of the tire pushes the insert towards the middle, giving it more of a "diamond shape". This then pushes the tire to the outside of the rim bed as well as the wings of the insert, so the bead doesn't have much wiggle room once it's installed, therefore less burping and easier tubeless setup.

Hopefully that makes sense, and isn't just me rambling.
  • 2 0
 @Tannus: I see, so in effect, an uninstalled insert is a sort of n shape, that's then squashed into the inverted v by the tyre sidewalls, and air pressure forces the tyre into the rounded shape. Then the insert stops the tyre collapsing in heavy cornering by pushing the sidewalls apart. Interesting. Can it get you to the end of a stage with a flat like Cushcore/Rimpact? And would that trash the "legs"?

 Been running these for a while now, I’ve had some tough times getting air to stay in my tires but once I worked out the kinks they’ve been amazing! The secret is to make sure your tires don’t already have holes... Just did a ride tonight on ~20 psi and had insane grip and still held plenty of speed for everything. I’ve been running the tubed version in my DH bike for two years now on the same tubes! These things are amazing!
  • 26 22
 I have been on these inserts for several months. The truest test that convinced me these were the real deal was racing at Bootleg Canyon. If you havent been to bootleg, it is pretty much a 3-4 minute razor sharp rock garden the whole way down. I raced with 21/22 PSI and had unreal traction, not to mention improved small bump compliance over the chatter. I did several rides on The Whole Enchilada in Moab as well and you really notice the damping of the inserts after 30 miles of continuous square edge rock hits. I honestly will not ride without them at this point.

 @slumgullion: this is true. I try to be as unbiased as I can though. Despite knowing all of the guys at tannus, I didn’t use the 1st version of the product. It didn’t fit my riding style and I wasn’t one to benefit from it so I didn’t use it. They knew that. I wanted to run tubeless inserts from day one. Everything I said above is my true experience with the product. Im not running anything on my bike that I don’t want or that I think doesn’t improve my performance. If I thought cushcore was better l, I would buy it. Just trying to give real world experience about a product that has changed my riding experience. But I understand there may be inherent bias

 I have been running these for a little bit and I really didn't think I would like them but I have to say I'm impressed. I can't speak for all the claims but certainly the rim protection is great and you can run lower pressures in your tires. Not stupid low pressures but I dropped min eby 2 psi in the front and 4 in the rear. Haven't had any hard rim hits or folded tires. These are good especially if you don't want to run cushcore but you want cushcore-ish rim protection. I think this is a super good option. Also they're not super heavy so I haven't really noticed any downisdes. Good Job Tannus!

 Very interesting. The first Maxxis tire in the video being installed with new Tannus insert is wire bead!!! and not the usual kevlar mantra of tubeless tires. But the PDF you attached here is much more interesting ( that with some laboratory test comparison results). The simplest, cheapest and lightest tire insert The Noodle achieves the same or better results than others especially in dynamic tests. No, it doesn't say everything especially about riding abilities but it's still interesting.

 My biggest concern with these inserts and the main reason I've yet to try CC or the like is getting nice sidewall cut 8 miles into the ride. I carry a tube and a boot for those instances and that will easily get you going in a few min and in most cases finish the rest of the ride in full stride. I've seen the CC method of trail side tube install and that looks like a pain... especially when you are with a group that is waiting on you to wrestle the tire back on the rim. I'd like to see haw Tannus suggests dealing with tail side repairs. Can you easily install a tube if needed? I don't want to be stuck riding out on a half flat tire. It looks as though Tannus has solved the installation issue... and the numbers seem convincing. But, I need to see this thing fully tested over a season of pretty harsh riding. Side wall cuts happen even on those DH casing, triple layer, Kevlar lined, with tiny bits of panther in them so you know they are good, tires.

 Cushcore has the XC version now which isn't nearly ad protective as the original and also weighs 150g. Like you I am curious how they compare. I have been really happy with Cushcore XC on my hardtail.
  • 10 4
 I have the CushCore pro. I also have the original Tannus which requires the use of a tube. CushCore has sidewall support when running lower pressure. The Tannus does not. It appears this newer version of Tannus will lack significant sidewall support. Lowering tire pressure is great, but without sidewall support at lower pressure its difficult to corner hard.

 I just put in a cushcore and I'd say it is hard to beat. Bought a set on sale and about $65/tire with valves. Install was really not that bad, took me about 15 minutes the first time. Very happy with the results. I don't tend to damage rims but wanted the other benefits and to have protection in the rear wheel for the bike park. I'm impressed they are making this one for $50/tire.....maybe will give it a try for another set of wheels.
