The new generation of racing tyres. New tread pattern for even better performance: “Diamond” tread pattern elongated in the direction of rotation for better ground contact. Curved side ribbing for excellent flex-free grip even in the wet. Kevlar® SiO2 3D Compound with added silica, for reduced rolling resistance and better grip in the wet. Corespun K 290 TPI casing, with mixed polycotton (cotton and polyester) and Kevlar® threads. High thread density of 290 TPI (equivalent to over 1.100 threads per decimetre!) ensures maximum comfort even at high inflation pressures. Added Kevlar® means even better cut resistance.
