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

Was a little tricky to put. Follow the guide and watch the video on YouTube.

I first installed Tannus on my rear wheel because that was where all my flats occurred. No more flats after that! It worked so well I installed one in the front wheel about a year later. I have experienced no flats since using these inserts and I ride on and off road. The inserts were difficult to install. I managed on my own for the rear tire but I absolutely could not install the tire on the front rim. I got everything in place inside the tire but the last foot of rubber would not go on the rim. I went to my local bike shop for help. The tech needed ten seconds to get the tire on the rim. Ten seconds! I asked how he did it and he just told be he'd been doing it for years. So, don't be put off by the difficulty of installation. Your LBS can take care of it for you.My bike has 27.5 x 2.35" mountain bike tires installed. Some people have remarked that their ride feel changes after installing these inserts. I have not noticed much difference since using Tannus. The wheels are more sensitive to the amount of air in the tubes. I used to run 50-55 lbs air pressure but now I inflate to 40. Some people run less air with these inserts. I have read stories with tires at 10-20 lbs but you will get a more squishy ride at that low pressure. Experiment with different values to see which works best for you. Note: If your bike is going to sit idle for a while (weeks or longer), I recommend you deflate the tires. This will allow the foam to expand back to its original size and the tires will be ready when you inflate for your next ride.I can recommend the inserts. I have nothing but good to say since installing them. They are pricey but I loathe flats and will do anything to help avoid them.

Llevo 3 meses usándolas y no he pinchado una sola vez, mientras que antes cada salida era al menos una ponchadura (rodada en montaña, ponchaduras por espinas principalmente). Pesan un poco más las ruedas pero no es algo que realmente no puedas uno manejar con um buen entrenamiento. Sensación un poco diferente a llantas normales, pero terminas acostumbrándote (casi imperceptible con doble suspensión). Muy recomendables.

Works well and so far I do not have any problems with punctures. Very glad I bought the product. A bit difficult to install. I bought Park Tool heavy duty tire levers and it works well installing Tannus Armour. I use the same tire pressure as before and changed nothing else.

Buen manejo en bajadas . Subidas un poco más de peso pero sirve de mucho .
