Tannus Armour
The Tannus Armour is a foam insert that you install over a bicycle inner tube and under the tire. It provides protection from 90% of punctures, absorbs vibrations for a smoother ride, provides increased grip, and lets you run flat for a period of time.
Crowdfunded projects pose a degree of risk for buyers, so be sure to do your research and fully read the seller's detailed description and production plans before plunking down your hard-earned money.
