A variety of 3 different tread patterns for all terrain conditions, from M (Mixed) and R (Rear) for those days with perfect dirt, to S (loose and Soft) for more aggressive Enduro trails and steep terrain. All designed to offer a complete range specifically developed for E-MTB. Featuring the innovative and patent pending HyperWALL™ construction, a Pirelli proprietary technology from Motocross tuned for e-bike usage, the riding quality and reliability (especially at low pressures) has evolved to become the standard.
