From gran fondos to epic solo rides, this lightweight composite bike is everything you need for your most challenging rides.
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. 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 tires up to 35c. 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.
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.
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.
Endurance road geometry, added tire clearance (up to 35c) and disc-brake integration allow you to tackle a variety of roads and conditions, from smooth pavement to rugged back roads and mountain passes.
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are the highlights of today’s electronic shifting systems:
Electronic shifting systems use powerful servomotors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with precisely and without chain rub.
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you’ll never have to replace a derailleur cable ever again.
