Grand Prix 4000 20-622 mm black
Grand Prix 4000 - real professional stuff! The activated silica compound improves the handling at stability limits and gives great rolling resistance. The anti-tear formula in the rubber compound prevents tread brittleness while increasing mileage performance.
The extra special thing about the GP 4000 and GP 4000S is their puncture
protection made from Vectran liquid crystal fibres. The patented
Vectran Breaker reconciles the conflicting goals of low weight, low
rolling resistance and top puncture and cut resistance in a fascinating
manner. The Vectran fluid crystals fibres were developed for airbag
systems in the automotive and aerospace industries. The material is
extremly tear and cut resistant and is also flexible. It retains these
properties even under constant stress - as opposed to Aramide.
