Feel the Foss

Latex and butyl are so pass. Sure, we have all heard about how good a latex tube rides. The high elasticity of the latex also adds to its superior puncture protection. Run a latex tube with a good quality clincher and you get close to the feel of a tubular. Tests have also shown that latex tubes provide less rolling resistance, which is a result of the high elasticity of the latex being able to conform to road imperfections, dispersing less energy. Latex tubes are far more porous than butyl, that is why we need to keep a close eye on the pressures before every ride and they cannot be patched or repaired.

Now the Foss. It is neither latex nor butyl. Foss is created from a proprietary rubber compound. As a result, it is lighter than the latex tubes currently out there. If you're wondering how much lighter - Foss tubes are on average 30% lighter than butyl tube offerings. Foss tubes are also explosion proof. By explosion, we are referring to that unfortunate experience of having a standard butyl tube exploding under high pressure when punctured - usually midride when you're cranking it out. Because it's made of a special rubber composite which is tougher, the Foss tubes will not explode. The unique material will remain stable if punctured and will seal. During testing, we have found the Foss to seal airtight around a puncturing object.

Foss EFT offers a ride quality and suppleness that is equal to high-end latex tubes, but still maintains a super stable feel at lower pressures. It holds air pressure far better than a latex tube and dig this - they're 100% repairable. Foss EFT is so easy to repair, you can do it on the road with a cigarette lighter to seal the puncture (kids, don't burn yourself). Once you are back home, whip out the Foss EFT repair pliers and repair even the tiniest holes with absolute precision. With the recommended Foss Pliers, the idea is to get more life out of your tubes.

Foss tubes are recyclable. The Foss material is an unvulcanized rubber which can be recycled with other thermoplastic rubbers. Toss them in the appropriate recycle bin when you're through and bask in the satisfaction of taking one small step towards saving the planet.

See what the Fuss is all about. Foss is the next step in the evolution of tubes:

  • Explosion Proof
  • Proprietary rubber compound
  • High stability under pressure
  • 100% repairable
  • Recyclable
  • Works in 700x25c tyres as well!
