From gran fondos to solo rides, this lightweight composite road bike features endurance geometry and built-in compliance. Smooth and fast, all day long.
Defy Advanced Pro features a host of innovative technologies including a D-Fuse composite seatpost and Contact SLR D-Fuse composite handlebar. These components 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 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.
FEATURES:
- Engineered compliance: Advanced Composite frame is specifically engineered for endurance road riding, delivering a smooth ride quality and less fatigue on long rides. The D-Fuse seatpost and handlebar absorb road shocks and vibrations.
- Total control: 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 tire 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.
