The 2016 Cozmic RX3.0 is Polygon's top of the line 29er hardtail mountain bike. It features a podium-climbing ACX Advanced Carbon frame, with ridiculously clean lines, stealthy internal cable routing, ride-tuned chainstays, and a carbon 142x12 rear dropout. The RX3 delivers extraordinary performance and is one of the best looking bikes Polygon have released for 2016.
The tapered head tube meets the top tube and downtube in a massive junction to keep the front end stiff for precise steering control which is confidence inspiring when hitting corners at high speeds. The uniquely shaped, square profile downtube which melds into a beefy bottom bracket amplifies torsional stiffness and maximizes power transfer. The RX3 features the new M8000 Shimano XT 36/26 crank that offers the optimum combination of light weight and stiffness to make every pedal rotation count. Short, asymmetrical chainstays supply superior efficiency and nimble handling, especially on tight singletrack. Chainstay mounted rear brake caliper positions the rear brake in the ideal position between the two stays out of the way, minimising the torsional forces of the rear wheel while braking. Finally, a 142 x 12mm rear thru axle securely joins the hub to the frame, strengthening lateral stiffness in the rear triangle for improved pedaling efficiency.
The RX3 is assembled with a plethora of beautiful parts and components. A Fox Float Factory front suspension fork with CTD remote and Kashima Coat keeps the front end of the bike in complete control. A Shimano XT 11-speed drivetrain is perfect for nearly any XC course. A 36/26-tooth Shimano XT crank is matched to a 11/40 Shimano XT 11-speed cassette to conquer brutal climbs and harrowing descents alike. Finally, a blisteringly-quick set of DT Swiss Spline One wheels with Racing Ralph tyres make short work of tight and twisty singletrack.
