Tannus Armour Tire Insert, No Flat Bicycle Tire Insert, Puncture Proof Bike Tube Protector, Stops Flats from Thorns and Goatheads

No better protection for daily commute 5Star

I purchased one insert as a trial since reviews were mixed as to how easy it would be to fit and what the ride would be like. In the event the fit was easy with my Schwalbe Smart Sam, Active, 2.60 tyres. Riding on the road I noticed no difference; over roots,, etc. it feels more comfortable. I've consequently ordered a second.

For £134 i expected to get x2 of the 26x4" armor, unfortunatly i was wrong and only 1 turned up, have spoken to tannus uk and the price for the 26" armor is £50 per item, trying to return the item isnt the best either, they require you to pay for return shipping which for the price is mad. avoid at all costs!!!!!!!!

This product is fantastic ever since I put it on my bike. I have never had a single problem with going over anything. obviously within reason of course...

I am changing this back to a Great 5 star review because this is a great quality product and Tannus shouldn't be criticized because they didn't do anything wrong, as it was an Amazon issue. Also these 26x4 are not easy to install but after having these professionally installed at a Specialized bike shop by a Specialized bike mechanic which costed an additional $195 on my electric bike the bike rides nicer and smoother then ever and so far NO FLAT TIRES... Thanks again for the High quality bike parts Tannus...

Ok so its 10/28/23 here in the Chicagoland area. I recently purchased ( 2 ) of these for my fat bike . Buyer beware , your current tubes will not work . I went with the recommended 26x3.0 tubes & they worked splendidly. Now onto the install . I researched the fat bike install on YouTube, I watched 4 different installs . The Tannus armor official website says to trim them PRIOR to install and use baby powder , I personally did NOT do either. I figured I'd attempt to install them without a trim because I'm paying for 100% protection. I want 100% protection, worst-case scenario, I'd pop them out and trim them down if need be . Thankfully I didn't. Lets fast-forward the basics and go to install , I pumped about 3 or 4 pounds into the tube before I installed tubes into armor , line up the stem properly and install the first part into the rim. I was certain to push the armor back the the back of the rim , it makes for a smoother install for remaining tube/armor . Constantly watching to see that the tube or armor are not kinked or twisted or you'll have waddle ( unbalanced armor/tube ) . Once you have the tire on both sides of rim , set the tire down on the ground and roll it 10 or 15 feet ( prior to pumping remaining air pressure ) . Once you feel comfortable with this. Pump a few pounds and STOP ! Check ✔ both sides of the rim thoroughly on the bead to make certain there's no bulging. Then proceed to fill tire to recommended capacity. ( My fat tires say 20 lbs. Max ) I'm a big guy ( 6' 240 lbs. ) so I'm going with 20lbs. A short test run is recommended before any serious riding . Check both tires again thoroughly after. I read multiple reviews on these installs here on Amazon, one bloke said he was a retired engineer and he spent hours attempting to install these , finally took his bike to a bike shop. I was a bit perplexed by this. So I did MY own research. Its not rocket science, doesn't take any special skills or fancy tools aside from the usual tools needed to change a tire. Takes a bit of patience and a little elbow grease. I hope this review helps you. And PLEASE don't trim down & throw away good money if you don't have to. Good luck and be safe out there 🙏... P.S. the total time for both tires took me less than an hour. That's popping them off the bike , breakdown & reinstall. * UPDATE * It's now 12/23/23 . I have successfully ridden over 1500 miles on the Tannus Armor & ZERO flats ! I'm a daily commuter who rides in rain & snow . I have hit some pretty gnarly holes and bumps on the trails and the pavement and I've not had a single issue .

If you have a 4 inch wide tire you're going to find these extremely difficult to install. The installation instructions are for a thinner tire , I think !! Terrible customer service and forget about any type of warranty, they make up unheard off rules so you can forget about getting any type of exchange or refunds. Another company that all it cares about is the Almighty dollar. Also the inserts stick like epoxy glue to the insides of your tire so you can forget about reusing them when you eventually have to replace your tire.
