The Maxxis Ardent Race 27.5 TPI Folding Tyre is ideally suited for technical XC race courses and endurance-length events. With its medium-height tread, the Ardent Race bridges the gap between the XC-oriented Ikon and the trail-oriented Ardent. The center knobs are ramped to reduce rolling resistance, and the side knobs are angled and stepped to give great biting traction in corners.
