Go longer, go faster, and smooth out rough roads with a frameset and integrated components that are engineered for compliance. From gran fondos to epic solo rides, this lightweight composite bike is everything you need for your most challenging days.

With the perfect blend of stiffness and compliance, Defy Advanced Pro delivers a smooth, fast ride quality even on rough roads. Its innovative technologies include a D-Fuse composite seatpost and Contact SLR D-Fuse composite handlebar (Pro 1 and Pro 2 models). These integrated cockpit components work as a system to add compliance and reduce road shocks and vibrations. The Advanced-grade composite frame is also integrated for disc brakes, with flat-mount disc brake tabs and 12mm front and rear thru-axles, plus clearance for high-volume tyres up to 35mm. The oversized and tapered OverDrive 2 steerer tube boosts cornering precision, while the MegaDrive downtube and PowerCore bottom bracket deliver precise handling and class-leading pedaling efficiency.

Key Performance Factors

Engineered compliance

Advanced 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 35mm) and disc-brake integration allow you to tackle a variety of roads and conditions, from smooth pavement to rugged backroads and mountain passes. The bike is also fully equipped to accommodate mudguards with mounts on the front drop outs, the back of fork crown, rear drop outs, back of seat tube and with a bolt in seat stay bridge.

  • 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.
