Frequently Asked Questions
How is this different from the Tannus Armour inserts?
The liners are simpler and lighter — they block punctures but do not provide run-flat capability. The Tannus Armour inserts are thicker, include tubes, and let you ride home even with a punctured tube.
Does this include tubes?
No — this is the liner only (set of 2). Use your existing tubes or pair with the Tannus Armour kit if you need tubes included.
