Specialized is not afraid to say that their Gripton compound is the best out there. And when combined with an ultra-supple 320 Tpi cotton casing, you get a tyre that's very special — you get the Turbo Cotton tyre. Both materials stand for master craftsmanship, and they work in harmony to reflect the dedication to building the world's fastest tyres. By bringing both of these materials together, Specialized has created the best clincher tyre out there. It provides a clear-cut performance advantage.
- Casing: 320 Tpi Polycotton.
- Bead: foldable.
- Compound: Gripton
- Flat Protection: BlackBelt.
- Size: 700x24.
An extra layer of uniquely-crafted fabric with highly resistant properties sits between the casing and the tyre to reduce the risk of punctures. The technology is higly recommended to be applied on the tyres intended for use in intense conditions with a high puncture risk.
The Gripton compound uses 'mostly synthetic rubber reinforced with silicon dioxide', which reduces the amount of energy lost through hysteresis. This basically means less deformation, less heat build-up, and a more efficient tyre with improved rolling resistance when compared to natural rubber. The Gripton compound is soft, allowing it to adapt and conform to rough surfaces. It has a durometer of 56 A, making it much softer than other tyres, meaning the tyre not only conforms to the surface it is rolling over, but also filters vibration, which produces a smoother ride.
