Climb, corner, and descend with speed and efficiency. From the mountains to the flats, in all types of conditions, this lightweight composite road racer takes you to the next level. FEATURES: Class-leading efficiency: With an impressive stiffness-to-weight ratio and updated aero tube shaping, this frameset is engineered to give road racers and riders superior climbing capabilities, aerodynamic efficiency and sprint stiffness for race-winning performance. Advanced aerodynamics: This is where the TCR&';s most quantifiable gains can be found compared to previous generation models. Every tube shape was analyzed, engineered and tested to create an overall structure with significantly lower drag at a wider range of yaw angles. Total control: Integrated disc brakes deliver smooth, powerful stopping power and modulation for added control in variable weather and road conditions. Flat mounts and new thru-axles boost stiffness and improve overall handling, while added frame and fork clearance allows for larger diameter tires up to 32mm.
