We all hear different things when we ride. What do you hear? For Downhill World Cup racer Luca Cometti, it's the raw sound of tires on dirt.
Tannus Armour gets rid of flat tires and smooth out your ride so you can focus on the parts of biking you love.
for more details.
"crap crap crap shit oh no! crap crap crap"
Is @Tannus pronounced Tan-us, like when people from jersey talk about themselves, or T-Anus as in "hate us cause dey ANUS"
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.
I dig it!
@tannus how strict is the width fitment? I run a slightly wider tire up front, tho is more of a 2.35 associating its self as 2.5
Shout out of appreciation for covering all questions and comments here!
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!
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.
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!
Need details fast / easy
Hey CushCore, have some spare time to test these?
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.
