Centuries, gran fondos and rough roads—there is no better road machine for long, demanding days in the saddle. The frame is handcrafted with Giant’s superlight, professional-grade Advanced SL composite with endurance geometry. Innovative features including flat-mount disc brake integration, 12mm front and rear thru-axles and the vibration-damping D-Fuse integrated seatpost deliver control and compliance. The oversized and tapered OverDrive 2 steerer tube boosts cornering precision. And the MegaDrive downtube and PowerCore bottom bracket produce sharp handling and best-in-class pedaling efficiency.
