PANARACER FLATAWAY KEVLAR PUNCTURE PROTECTION TYRE LINER
Light and supple, produced from Kevlar® fibres that are woven together to produce a “bullet-proof vest” for your tyres. 1 FLATAWAY FITS ONE WHEEL.
We tried stabbing one of these with a knife and guess what - it couldn't go all the way through. Jenni has been testing one on her commuting bike rear wheel - the tyre is dead and it's been 3 months and no puncture yet!
This is just another level of protection against punctures - there's no such thing as puncture-proof, but you can get close!
