Proven through countless pro wins, this lightweight composite cyclocross bike delivers quick acceleration, smooth handling and total control on dry pavement, loose dirt, deep sand or slick mud--everything you need to aim for the podium. ELITE LEVEL EFFICIENCY - Advanced-grade composite frameset is 17.5 percent lighter than the previous generation while retaining its best-in-class torsional/pedaling stiffness. TOTAL CONTROL - Integrated disc brake technology with flat mounts and thru-axle hubs, combined with tubeless ready Giant WheelSystem, delivers added control in variable conditions and all types of weather. SMOOTH RIDE QUALITY - D-Fuse composite seatpost helps absorb bumps and vibrations, and you also have the option to switch to a standard 30.9mm round or dropper post depending on your riding style and terrain. ADVANCED COMPOSITE TECHNOLOGY - Giant's High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction. OVERDRIVE 2 - 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. COMPACT ROAD DESIGN - 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. TUBELESS SYSTEM - Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant's Tubeless System makes it easier than ever to experience all these benefits.
