Description

Anti-Puncture Bicycle Inner Tube
By Foss
Features

x High puncture resistance because they're made from a highly polymerized un-vulcanized rubber composite, which is special because if punctured the tube material forms an air-tight seal around the thorn, nail or puncture intent sliver of glass, retarding the speed of the leaking air. This means that you won't know you've punctured as long as the offending item is still in the tyre, or at worst it will go down incredibly slowly, allowing you to get home.

x The Foss tubes are environmentally friendly because the modified thermoplastic elastomer compounds TPE they are constructed from means they can be recycled with other TPE products, thus minimizing waste & protecting the environment.

x Tubes weigh about 30 less than other tubes, and they have blue valves, which is cool.

Remark: The price is for 1 pcs /Only 1 piece in 1 box
