STAY SMOOTH, EVEN ON ROUGH RIDES. THIS ENDURANCE ROAD BIKE IS PURPOSE-BUILT FOR YOUR LONGEST, HARDEST RIDES.

This lightweight Advanced-grade full carbon composite frame features road endurance geometry and engineered compliance for a smooth, high-performance ride. Its tube shapes are optimized to absorb road shocks and vibrations, yet they’re still stiff in ways that matter—for pedaling efficiency and precise, stable handling. It’s actually crafted with specific carbon layups to give it just the right feel. And integrated disc-brake technology, featuring flat mounts and 12mm thru-axles front and rear, gives you added control in all types of weather and road conditions. Tubeless ready

  • Weight
    The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
