The Grand Prix Classic lends that certain something to any classic or modern steel bike.
Ultra-modern technology with a retro look - nostalgia without compromise puncture protection thanks to PolyX Breaker® puncture protection
Excellent grip, high mileage and efficient rolling thanks to the BlackChili compound
A new relationship between grip and rolling resistance.
This unique tread rubber mixture which is only produced in our German factory has revolutionised bicycle tyres. BlackChili Compound improves rolling resistance by 26 % and provides 30 % more grip than activated silica compounds. Premium tyres with BlackChili Compound also impress with higher mileage and unlike many multi-compounds, provide a constant ride from the first to the last kilometer.
PolyX Breaker® puncture protection
With our PolyX Breaker®, we bring our car expertise to the bicycle tyre segment: Polyester has been used successfully for years in car tyres and been tried and tested many times. The extremely resistant polyester fibre is woven tightly crosswise. In this way, a very high fabric density is reached which not only makes the Breaker more resistant to foreign objects but is also especially resistant to punctures. The rolling resistance is also not negatively affected by the PolyX Breaker®.
