The XQUARONE EX Series is a departure from the old way of classifying bikes and creates a new paradigm where travel no long determines discipline. The NAILD suspension design works in conjunction with Polygon's frame construction to give a ride unlike anything else. The bike is designed to have a short rear end for tackling technical terrain and to provide quick cornering. Equipped with the elevated chainstay that is unique to the NAILD R3ACT- 2Play Suspension System, XQUARONE EX acts as an extension of rider’s movement. XQUARONE EX helps riders get more speed and extends their riding range. XQUARONE bikes are able to move over obstacles quicker which improves lap times, reduces rider fatigue and increases on trail confidence. All XQUARONE EX frames are built around 27.5 wheels and feature a full ACX carbon frame with 180mm suspension travel.
