As a thoroughbred front tyre, the Racing Ray ensures precise steering response, reliable conering and confidence-inspiring grip right up to the limit. At the same time it allows for strong, controlled braking under all conditions. the stable, barely deformable shoulder blocks support a direct riding style even during extreme cornering.
Despite its aggressive tread, it rolls surprisingly smoothly, quickly and quietly - on its near-closed centre strip of offset centre blocks. With its many lengthwise gripping edges, the tyre constantly strikes the right balance between low friction and grip. It's a tyre that should never be underestimated, no matter the angle or speed at which you ride. The transition blocks between the should and centre enable a continous gripping edge. The overall open tread pattern ensures great self-cleaning. 
Super Race
In no other discipline is the focus on rolling resistance and weight as critical as it is in cross-country and marathon competition. With the Super Race construction, Schwalbe are also setting new standards in suppleness - no other carcass glides so silky smooth over the ground, thus providing traction, like Super Race does.
