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.

## 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!!!!!!!!
