Continental Grand Prix 4000 - 650 x 23

The Grand Prix 4000 works on every road surface, transforming the demands of different styles of riding and supplies extremely long-term performance. Utilizing new Vectran material, these tires are lighter, have increased cut resistance and keep their strength in wet conditions. Activated Silica Compound (ASC) increases the handling threshold for even safer yet faster cornering and reduces the rolling resistance. New anti-cracking formula prevents UV light from damaging the compound and increases mileage performance. Tread wear indicators to help riders gauge the life of the tire; you won't replace it prematurely and you won't risk safety by riding beyond it's life.
