G-One Speed is a promise of maximum speed! This tyre extends the range of use for every road cyclist. It rolls fast on the road, but at the same time safely on unkept cycle paths and gravel roads.
The turn-up construction integrates Tubeless Easy Technology in the most progressive way possible. Two carcass layers underneath the tread renders the tyre smooth, comfortable and puncture-resistant, while three lateral carcass layers ensure high cut-resistance.
Super Ground
Combines light weight and stability. Feels comfortable in any terrain. Balanced ratio of puncture protection and smooth rolling. For flowing trails, long rides and any terrain.

New Boomerang profile for best traction uphill and ideal rolling behavior.
Super Race carcass (Souplesse construction) for a particularly smooth ride with low rolling resistance and high impact protection.
Angled side lugs create in conjunction with the Super Race carcass best cornering grip.
