WHAT IS GRIP?
Grip is the tire's ability to respond to the demands imposed by the cyclist regardless of the conditions (braking, traction or cornering).
In MOUNTAIN BIKE and CITY TREKKING, grip is linked mainly to the tire's tread pattern, the inflation pressure and the composition of the rubber compound.
For ROAD TIRES, grip depends mainly on the composition of the rubber compound, the inflation pressure and the match between these 2 parameters and the road surface.
On wet surfaces, despite the small width of the contact surface with the road - 7 to 9 mm depending on the tire size - , the high tire pressure of around 7 kg / cm² (or 7 bar) on the wet surface is sufficient to cut through the film of water, thus enabling the tire to grip the road.
