The Schwalbe Black Jack Active Kevlar Guard Wired 26'' Mountain Bike Tyre is much more than just a basic quality. The foundation of all Active Line Tyres is a high-quality 50 EPI carcass. Coarsely woven 20 or 24 EPI carcasses can no longer be found in Schwalbe's range. The much more densely woven 50 EPI carcass is far more puncture resistant and robust. At the same time the fabric needs less rubber coating and thus has a reduced weight. Naturally every Active Line tyre has a Kevlar Guard belt, a balanced rubber compound, plus a functional and attractive tread design which will cope with any conditions. From dry hard pack trails and muddy trails with it's large wide spaced knobs. Simply said the Black Jack Tyre is reliable, brand quality!
