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.

*In the bicycle industry, suppliers and factories sometimes change specs without notice and state that they are "subject to change without notice". This is because bicycles are made from hundreds of parts which come from dozens of vendors. Parts are sometimes updated to the most current production generation/iteration one gets better or more current parts or a comparable part. Product specifications are subject to change without notice.
