Defy Advanced 1

2019

Choose the longer route. Climb higher mountains. This all-new endurance road bike is purpose-built to help you tackle long-distance road rides in all types of conditions. It’s smooth, it’s efficient, and it’s fast.

Ride farther and faster with an all-new carbon frameset that’s engineered with endurance geometry and built-in compliance. Handcrafted with Advanced-grade carbon composite material, it’s engineered with tube shapes that are optimised to absorb road shocks and vibrations. And the frame is still stiff in all the ways that matter—for pedaling efficiency as well as steering and cornering precision. It’s made with a specific carbon layup to give it just the right feel. And for added control, it features integrated disc brakes with flat mounts and 12mm thru-axles. The D-Fuse seatpost and handlebar system also help reduce road vibrations, adding to its smooth, compliant feel on the road.

Key Performance Factors

Engineered compliance

Advanced Carbon Composite frame is specifically engineered for endurance road riding, delivering a smoother ride quality and less fatigue on long rides. The D-Fuse seatpost and handlebar system works seamlessly with the frame to absorb road shocks and vibrations.

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 rough roads.

Versatility

Endurance road geometry, added tyre clearance (up to 32mm) and disc-brake integration allow you to tackle a variety of roads and conditions, from smooth pavement to rugged backroads and 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.
