Most people don’t focus on pedaling efficiency when it comes to their downhill bikes, but a major factor in the design and development of XQUARONE DH was in the pedaling capabilities. Polygon worked closely with the NAILD team to create a system that offers a truly capable downhill bike that can also be pedaled back up a majority of trails. When ridden with the suggested sag, the XQUARONE DH has between 98% to 110% anti-squat value throughout the entire gear & travel range. Polygon's goal while designing the new XQUARONE DH bike was to make a bike that is fun to ride. For this very reason we have chosen to build this bike around 27.5 wheels. We intentionally bucked the trends in an effort to offer the most enjoyable ride to a wide variety of gravity fiends looking to have fun on their downhill bikes, whether it be shuttling laps on local trails or riding the bike park.
The uniquely shaped frame is fully carbon fiber and weighs 8.8 pounds (with shock) and top spec’d complete bikes weigh less than 32 pounds. Thanks to our close relationship with NAILD, we’ve been able to work together closely to integrate several key features into the new XQUARONE DH. To keep the back end short and stiff, we designed the bike around 440mm chainstays length with Super Boost 157mm rear wheel spacing. To further ease any stiffness concerns we’ve incorporated 34mm Torque Caps on non drive set of the rear hub to keep the rear wheel tracking straight and true.
In keeping true with the latest technological advancements, the XQUARONE DH utilizes 225x75mm Metric shocks with a Trunnion mount. Much like our XQUARONE EX line of bikes, the DH models utilize the NAILD R3ACT 2 Play system. The DH frames however, use the Hit It category of tuning that we developed with NAILD and our factory athletes. The Fox Factory X2 shocks are custom-tuned with incredibly light damping circuits to give us the famous R3ACT ride our fans have grown to love. By reducing the damping restrictions in the shock and allowing the suspension design’s kinematics to handle the heavy lifting, we’ve created a bike that offers rear wheel compliance unlike anything you’ve ridden before.
