| The all new GP4000 Tubular may be missing the aura of the old champion, but the challenger is enticing professional cyclists with its new technology. A seamless casing design improves the rim seating, uniformity and rolling resistance. The name, the dynamic tread design of the Grand Prix 4000 and of course a Vectran puncture protection breaker state the high ambitions of this new tire. Naturally, both competitors enter the race with innovative Black Chili tread mixture. What will you fit to your carbon race wheels? |
