The Grand Prix 4000 S II is the ideal combination of comfort, puncture protection & low rolling resistance. It's the perfect all-rounder for all conceivable conditions with excellent puncture protection thanks to Vectran™ puncture protection & BlackChilli's high mileage rolling efficiency.
Transparent Sidewall: The tire sidewall is left without the outer most rubber layer so the casing ply is visible. The bare casing ply gives the tire sidewall a natural, retro appearance that compliments older bikes & steel frame bikes very well.
Reflective Sidewall: A thin, silver light-reflecting strip on both sidewalls that adds visibility & safety to our city/commuter/urban tires.
All bikes come with 2 free tune ups. Please call if you have any questions or you want the price for the bike outfitted in a different way then it is pictured.
