## Description

Tannus Armour is the ultimate in tire protection and performance for all levels and styles of riding. Sitting between your tire and inner tube, the Tannus Armour provides 15mm of puncture protection on the top, as well as 2mm of sidewall protection from sharp objects and rocks. Whether you are a city biker, adventure tourer or prefer the off-road, downhill or gravel trails, Tannus Armour gives you increased grip and vibration dampening for a smoother, more comfortable and enjoyable ride. Tannus has been developing tire technology since 2003 and we are the number 1 brand of airless tire technology in the world. At the heart of Tannus is our patented Aither Technology. Aither is a multi-cell foam compound that forms the structure of the Armour.

Review: Extremely Dependable - No better protection for daily commute 5Star
Review: So far so good - 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.

## Features

- STOP BUYING & PATCHING TUBES: Our patented foam insert is engineered to stop punctures while improving the comfort of your ride.
- TRUSTED BY PROS: Professional MTB teams use Tannus Armour to ride harder without fear of pinch flats or thorn punctures.
- NEVER GET STRANDED: Our inserts convert your tires to run flat so you can finish your ride regardless of having air in your tube.
- BETTER HANDLING THAN SOLID RUBBER: Our armour IMPROVES your ride handling unlike solid rubber tyre replacements.
- FAST, EASY INSTALL: Average installation time is 10-15 minutes.

## Questions & Answers

**Q: Will this work with wtb 650b x 47c road plus tires?**
A: They come in all sizes

**Q: Will this work on a 700 x 25 tyre?**
A: Ahahahahhahaha.. Nope, I had to get therapy after my unfortunate run in with these. If you are getting loads of punctures on a commute then buy solid tyres and have them fitted by your nearest stockist, that or practice repairing punctures as these are not fit for purpose.

**Q: Hello my question is whether I can still use the normal inner tube size of whether this has to be adjusted**
A: No, you HAVE to use a size smaller inner tube. The liner fills the inner space so a smaller tube is required.

**Q: Why are you selling the 26 in fat bike for that price other than greed ? Disgraceful**
A: Well I bought it and it works well, fiddly to fit but good once sat correctly. Is expensive though

### ⭐ TOTAL RIP OFF!!!!!
*by D***. on 15 October 2022*

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!!!!!!!!
