Choose the longer route. Climb higher mountains. This smooth-riding endurance road bike is made for long-distance rides on all types of roads.

Key Performance Factors

Engineered compliance

Advanced Composite frame is engineered for endurance road riding. The D-Fuse seatpost and handlebar absorb road shocks and vibrations, and its smooth ride quality means you’ll feel less fatigue on long rides.

Total control

Seamless disc brake integration including flat mounts and 12mm front and rear thru-axles produces more consistent braking power for better control, even in wet weather and on rough roads.

Versatility

Endurance road geometry, plenty of tire clearance (up to 35mm), and disc-brake integration allow you to tackle a variety of roads and conditions, from smooth pavement to rugged mountain passes.

  • 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.
