Description
Wave goodbye to pesky punctures with Tannus Armour tyre inserts! This clever insert delivers a full 360° shield, guarding against thorns and sharp objects - as well as pinch flats.
Crafted from a patented Aither multi-cell foam, it’s remarkably lightweight yet incredibly tough, ready for anything the road (or trail) throws your way. Snugly nestled between your tyre and inner tube, it boasts a generous 15mm of top protection and 2mm on the sidewalls.
No more worrying about inner tube contact with your rim during those bumpy rides. The Armour even steps up to protect your rims from those super hard knocks. Experience superior stability in corners thanks to its impressive sidewall support, preventing tyre buckling.
This means you can happily ride with lower tyre pressures for ultimate grip and comfort. Imagine cruising roads at 1.7-2.1 bar or conquering the off-road at 1.0-1.4 bar!
Plus, installation is a doddle, just like fitting a regular tyre, and it's completely faff-free. Get Tannus Armour working hard to protect your tubes, save you time and improve safety on your bike!
