The Giant Defy Advanced SL 12018 is superlight and engineered to go long. From gran fondos to gritty epic rides, this is the pinnacle of endurance road.
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.
