The Continental Grand Prix 4000 Road Bike Tires feature cutting edge road tire technology using a new patented Vectran puncture resistant belt.
Vectran is an extremely strong and light synthetic fiber similar in property and performance to Aramid/Kevlar, yet is far more flexible for reduced rolling resistance and holds its high strength and puncture-resistant properties better in wet conditions
The Grand Prix 4000 road bicycle tires have a highly technically advanced tread compound that uses an Activated Silica as a filler. This compound is unique in the use of saline to increase binding of the silica to the rubber. The result is a compound that is extremely low in rolling resistance and has outstanding grip in dry conditions.
The Grand Prix 4000 bike tire uses a new anti-cracking formula that prevents UV damage and increases mileage
