Defy Advanced SL
There is no better road machine for long, demanding days in the saddle. The superlight frameset is handcrafted with Giant’s pro-level Advanced SL composite and engineered with endurance geometry. Its innovative technologies include flat-mount disc brakes with 12mm front and rear thru-axles and the vibration-damping D-Fuse integrated seatpost. The oversized and tapered OverDrive 2 steerer tube boosts cornering precision. And the MegaDrive downtube and PowerCore bottom bracket deliver precise handling and class-leading pedaling efficiency.
Giant’s Professional Grade raw carbon material is woven in our own composite factory using our most advanced engineering and construction methods including: Continuous Fiber Technology to add strength while reducing weight; Carbon Nanotube Technology resin to improve impact resistance; and Fusion Process for lighter, stronger frame junctions.
Introduced by Giant with the professional Team ONCE in the 1990s, Compact Road revolutionized the look and feel of high-performance road bikes forever. A downward sloping toptube (from the headtube to the seattube) creates smaller front and rear triangles for a lighter, stiffer bike. It also makes it easier for riders of all sizes to have a perfect fit.
The D-Fuse seatpost and handlebar were designed to function as a system, absorbing road shocks and vibrations so you can ride farther, faster.
The most advanced steerer tube technology in today’s Giant bikes. Designed to offer unprecedented front-end steering performance, the system’s oversized headset bearings (1 1/2” lower, 1 1/4” upper) and tapered steerer tube work in harmony to provide supreme steering stiffness.
Giant’s chainstay integrated, wireless data transmitter. The removable transmitter sends wheel speed and cadence information directly to any ANT+ compatible computer.
