The Continental Grand Prix Tyre is a comfortable all-rounder that has been written into cycling history. With the PolyX-Breaker we introduce technological know-how from automotive manufacturing to the bicycle tyre sector. Polyester has been used successfully in car tyres for years and has proven its worth. The extremely resilient polyester fibre is woven finely as a cross mesh. This way a high density of fabric is achieved which not only makes our breaker more robust against foreign objects, but also makes it particularly puncture resistant. The BlackChili compound is the unassailable specialists for combining compound characteristics. Grip and rolling resistance are no longer adversaries. Outstanding handling characteristics from the first to the last kilometre.Neutral design and solid construction for sporting rides at the highest levelPuncture protection, comfort and decent grip make every ride hassle freeExcellent puncture protection thanks to PolyXBreaker puncture protectionExcell
