Revolutionary. This word can be used to describe the first all-round puncture protection for bicycles. The Tannus Armour increases puncture resistance not only on the tread but also on the side walls. Another advantage is that the tire can be driven with less air pressure for more traction without sacrificing safety. The Tannus Armour is an easy-to-mount all-inclusive package for more fun driving! You can purchase the Tannus Armour either as a single puncture protection insert or as a combination with a matching tube.
