Video: The Soundtrack of Luca Cometti Riding Tannus Tire Inserts

 Copycat! These are my sounds.

 @pioterski: what about "uah" or gruning like "ahrgh"
or "uff"

 I'm partial to Homer screams, myself: www.youtube.com/watch?v=Q0w5HuIfYDc

 @rezrov: we need to meet, greet and ride.

 @davidpr2: AHHHHHHHHHHHHHHHH!

 @davidpr2: There are many sounds that I can even find a readable notation for.

 @rezrov: I'm right there with you. People look at me like I'm crazy when I do it uncontrollably.

 There was a set of whoops in there man..

 @mtbmaniatv: also the first 30 seconds of video has a good amount of rock

 I was thinking the same thing. My commute to work has more roots and rocks than that trail. That said, it was some sweet riding.

 Its actually pronounced "Tan-nus", but we're ok with "Tan Anus". A**less chaps on a sunny day go a long way.

 @Tannus: did i miss where the weight was specified?

 @Jimmy0: You didn't miss anything, It's just on our website. Around 300g per insert. That's about half the weight of a true french Baguette.

 @Tannus: there’s a fine line between rubbing in some sunscreen, and rubbing yourself with sunscreen.

 @Tannus: Literally scoured your website and it doesn't have weights anywhere. Post weight (including necessary tube) please in all sizes.

 @tandan83: We’ll talk to our IT guy and have those uploaded tomorrow first thing!

 Putting a set in my bike added just about 1.5lbs to it. About the same weight as switching out to dual ply tires, but with added benefit of vibration damping and not having to deal with sealant.

 @Tannus: does that include the whole setup or exclude the tube portion?

 @Jimmy0: it’s just the Armour, tubes add a little extra (120-150g per tire).

One of our riders switched to an EXO casing tire with our Armour/tube from a DH casing setup tubeless, and has yet to flat, and his bike is lighter than before.

 @Tannus: gotcha. And what happens when you hit the same rock that would have sliced your tire without armour? Presumably you'd still slice it and the armour would just be exposed? How long you think someone can ride on That?

 @Jimmy0: We did the majority of our testing in Moab, home of the cut sidewall. Two of our riders had an exposed sidewall, but neither has had a flat. How long will it last? One of our testers has been riding on that tire for 6 months and still hasn't flatted.

 @Tannus: That's pretty crude marketing....

I dig it!

 @Tannus: All chaps are @ssless. It took me well into my 40s to figure that out.

 Happy to help! We recommend tires from 1.9" to 2.5", though we've had people running them in 2.6" without problems. It sounds like Armour would solve a lot of the issues you're running into!

 CaptainMarvels list of priorities in order 1. MTB ride quality and inserts 2. Some guy named Thanos

 Thanks for asking! As good as tubeless is, it still seems to add headache to almost every ride. Since Armour fully protects the tube, you can slam rocks, land sideways, case jumps, etc without having to worry about flatting or cutting a sidewall. But we’re bias.

 @Tannus: the flat protection looks cool. But like I said I’m more interested in the effect on ride quality. Can you speak to that compared to Cush Core?

 @BiNARYBiKE: Since the Armour goes in-between your tube and tire, it puts our material (Aither) next to the tire so it absorbs initial vibration. Other inserts sit at the bed of your rim and absorb big hits, but with the material on the outside it significantly reduces ride chatter as well as big hits. One of our riders who came off of one of the other inserts said that "Not only does it get rid of the small bump noise and chatter, I haven't heard a single rim ping yet. I can't say the same of my other inserts."

 @Tannus: Interesting. Cush Core's big thing is that the initial impact is met with air in your tire, and then dampened by the insert. Yours appears to be the opposite. Curious what difference I'd notice on the trail. Anyway, I'm all for these innovations. Of all the technological progress in MTB, it blows my mind that flat tires are still ruining race runs and weekend rides in 2019.

 @Tannus: I don't quite understand your system from looking on your website.

In the pictures (or computer renders) it appears like the tube is at some distance from the center channel of the rim bed so the valve stem kind of bridges a gap between the two. I'm sure that must be a mistake in the drawing. The tube sure must be resting against the rim bed, shouldn't it?

In another drawing (cdn.shopify.com/s/files/1/1756/9757/products/armour-pinch-flat_1800x1800.jpg?v=1548448339) which shows what's supposed to happen when you hit a sharp edge (which would pinch flat conventional systems) a gap seems to develop between the insert and the tire, so there must be air going in there. Where does it come from? Would it suck ambient air through the rim bead or well, where does it come from? And does it also evacuate quickly enough when the tire springs back to its normal shape?

I never went "conventional tubeless". I just went straight from (latex) tubes to the Schwalbe/Syntace ProCore system. Tire installation is easy even with a mini-pump and bare hands (no tire lever). Only downside I feel is that eventually sealant seeps into the (pretty complex) valve and there is no way to clean it out. My plan is to use different valves for tire and tube so that should sort it out. My rims already have two valve holes so that shouldn't be too hard. I'm also looking at other alternatives but being able to install the tire with bare hands and a mini pump (no disposable CO2 cartridges) is a must for me. So your system does look interesting. I'm wondering though, I currently run somewhere between 5 and 6bar in the tube and 0.9bar in the front tire and 1.1bar in the rear (26x2.4" resp 26x2.35" tires). Is your system similar in that you're supposed to run a high pressure in the tube and then the insert is the soft bit? Then what pressure is it like? If your insert is like a 1.5bar tire (which seems to be what tubeless people are running) then for me that would probably relate to getting less grip than what I'm currently enjoying. I do get that your inserts provide damping which air in the tires obviously doesn't.

Is your tube very special/specific or could I use any tube should if for instance I happen to damage the valve and I'm away from any shop that stocks your products? Also I have a strong preference for Schaeder over Presta valves but ProCore kind of forced me into that. I'd be glad to go back to Schraeder.

Finally, props for offering a 26" version!

 @vinay: Awesome questions!

I think the easiest way to answer the question about where the tube sits is to watch this video about how to install it. Essentially the tube sits on the rim just like a tube would in a tire/tube combo without Armour. The only difference is there is an insert sitting between the tube and the tire with Armour inserts: www.youtube.com/watch?v=F1t0Xg5Xu7k

We're actually the opposite of that system, we recommend lower pressures in the tube than you would run with tubeless, as Armour cushions the impacts the tube receives and prevents pinch flats. We've been running 4psi less or so on our personal bikes, but it's something we're always experimenting with. You can run it higher if you'd like, the Armour will help with the small bump vibrations.

Any tubes work! Presta or schrader. We just recommend going down a tube size -- if you're running 2.5s for instance, use a tube for 1.9-2.1" inch tires.

 @Tannus: Thanks for the answers, sounds great! I live in The Netherlands so I'd appreciate puncture protection on my commutes too (somewhere between 100 and 150km a week). There never is a good time to puncture, especially not with two kids on your bike! I'm running Schwalbe Marathon Plus tires on these (with a thick breaker layer in the tire) so running your system would allow me to get away cheaper (thinner) tires in the future. Good stuff.

I just visited tannus.world which appears to be your Dutch website but even though there is a mention about the aither 1.1, it doesn't seem to be available in that webshop. I live just north of Amsterdam so would the system be available in your Amsterdam (physical) shop, in Purmerend (which appears to be just a PO box) or would I be best to get the system from your regular website?

Yeah I've got good experience with the higher pressure in the ProCore tube in that it presses the tire to the sidewall so even at low pressures in the tire I still don't get tire roll when riding off-chamber corners. Or would the insert itself already prevent tire roll?

Glad about 26" for my mountainbikes and definitely glad that I can use tubes with Schraeder valves!

 That’s for our tires, the 27.5 are labeled as 2.0-2.5 but work just fine on 2.6! Rim width doesn’t matter with the inserts. Great question!

 Our inserts go in-between your tube and tire to protect the tube from going flat from sidewall cuts, pinch flats, and anything sharp you might hit.

 Jokes on you @OzzyPhoto I am! and they are the bomb! Look forward to helping you photograph the riders!

 I don't know who you are, but I like you.

 As the guy writing this, I'm 160lbs and I'm running 18 PSI on my DH bike, and 10 PSI when I go do big-mountain freeride. My tubeless I wouldn't dare go below 20psi.

 @nug12182: not mutually exclusive

 Talk to your local bike shop, we hate how expensive shipping to CA is too....

 580g for a pair of 27.5" pair. Then 250g for some Light weight tubes. 750g Total. BUT.....250g of Sealant, Valves 20g, rim defender can be between 100g -250g.
You need to use heavy duty tyres to prevent punctures. Switch DH to Trail casing tyres can save 600g.

Armour set up Weight: 830g
Tubeless set up: 400gish depending on rim defender option.

Change your tyre casing?
Many possibilities but overall i would say you wouldn't notice.
You would then gain, No burping, No clogged up valve, resistant to tyre cuts, no sealant change every 6 months, no compresses / air can need to inflate, Run flat protection.

 @Onzajoe: Well, there you have it folks. Couldn't have said it better.

 Yep! We're working with a distributor down under right now, you should see them available there within the next 2 months. Or we can ship from the US. Or, find someone flying from the US to Australia, convince them to buy new clothes while down there so they can fit your Armour in their suitcase. Works like a charm.

 @Tannus: cheers guys very helpful and cant wait to get my hands on a pair.
