Tannus lining

[cleo1943]

I recently had my third flat on my Level in 2,000 miles. At 77, I can’t have flats; they are too much for me. My hard tail had 6,000 miles when I gave it to my daughter, and never had a flat, because the shop put on tubeless tires and added sealant every few months and I used it every day. It would be expensive to change the Level to tubeless so the shop suggested Tannus linings. However, I learned from watching podcasts by scientists regarding covid, is to look at the data. For example, randomized groups riding in similar areas, one group using the liners, and the other not, in order to determine if liners made a difference. I can’t find any such data. I can’t afford to throw away money on liners that don’t work. Anyone know of objective data as to the effectiveness of the Tannus liners?

Frankly, I put them in based on common sense reasoning. 3 rear flats in less than a year from pretty small items made me willing to try something and the TAs just made sense. I guess time will tell. I really had no desire to use any slime products plus they offer run-flat-style protection.

We have the same issue: too many flats. I am relatively certain that tubeless/ slime works. As I said, not practical for the Level to convert. I am interested in how it goes for you. Would you mind checking back in from time to time and tell us your experience? That would be helpful. ThAnks.

Sure. I installed them on my Allant+7 with SCHWALBE G-Ones less than a month ago and had my Trek guy install them on my wife’s. Just remember that nothing is impervious to flats except a solid tire.

I have installed them on other people's "Fat Bikes." One was a 2Kw monstrosity. Overtime the density of the foam increases as it collapses. Tannus will deaden ride feel. In my opinion they are kinda intellectually disabled in the same vane as a Fat Bikes with a throttle.
Other ideas: Use eBike speed rated at 50Km Schwalbe tires with flat protection of level five or higher. Use Mr Tuffy or similar tire liners. Use Aerothan tubes with a slosh of Stan's in them. Aerothan will feel more like tubeless. The opposite of deadening the ride with Tannus.

Ive noticed a bit different feeling with the Tannus Armor but higher psi in the tube makes a definite improvement. Not sure how I’d feel about solid tires.

Yeah but the higher psi just makes it collapse faster. I have seen Tannus out of a wheel that is paper thin. With that said, I am using it in several bikes myself. Long term we will have to see if the effort and cost is worth it. HOWEVER, I am also using it as part of a multi-pronged solution.

1. A thick tire casing. On the front of my Bullitt, thats a 20x2.40 Super Moto X. On the back its a Marathon Plus. Both tires are e50 and belted.
2. Tannus under belt and the e50 tire.
3. A thorn-resistant tube under the Tannus and the belt and the e50 tire.
4. Inside the tube and under the Tannus and the belt and the e50 tire I am using a heavy duty sealant capable of stopping serious holes. FlatOut.

On my tubeless bikes, I use Flatout alone as a sealant and it has worked miracles with multiple nails (at once). Just a (fat) tire and the sealant.

These days I am riding big heavy cargo bikes that would need a pickup truck to get them home. So flats are a big no-no.

I'll put in my psuedoscience for tannus from the ozemtb study.

Small cohort - our family is running 4 mountain bikes

My emtb - 3 years, about 6000 km but mostly rocky mtb riding.
The first 2000 km was tubeless, during that time I threw out 2 front and 1 rear tyres due to sidewall damage causing leaks despite stans sealant. Several rides were cancelled due to random early morning flat syndrome....and many hours were spent splattering sealant around the shed during tyre changes.
Then I discovered tannus - now over 3000 km and not a single flat or problem except for the gassle during tyre changes.

mtb 1 , Norco optic - 2017- 2 different teenagers during that time. The first 2 years were tubeless, one walk home with a sliced sidewall ( tannus would still be rideable, but I doubt a tube would have helped) . Endless hours spent at the lbs / in the shed troubleshooting an annoying leak ( split rim tape) ....and then we changed to tannus and haven't had a problem since. Actually, we have had 2 broken spokes - the lbs refuses to work on tannus so I have to do the repairs myself.

mtb 2 - 2019 scott genius - always tubeless because sprogette dislikes the dead feel of tannus. 2 tyres thrown out due to sidewall damage / leaks , I'd say 10 early morning flats - but all responded to pumping up with fresh sealant. Three sets of clogged valve stems needing replacing ( coming up to no 4 as of wednesday)

mtb 3 has tubes , but sprogette 3 is gentle with her bikes


NB tannus definitely has a dead feeling, it's a small compromise for the reliability. It also doesn't roll as well. Forget about riding an e bike on flat tannus - I can JUST ride a narrow (2.3) tyre light mtb with a flat tannus , but the wider 2.6 on my emtb feels dreadfull
