Advanced Composite Technology
Giant's High Performance-grade raw carbon fiber is used to produce custom composite material in our own composite factory. Extremely lightweight, stiff and compliant, these handcrafted frames feature high performance-grade carbon material.
Compact Road Design
In the late 1990s Giant pioneered a radical new frame shape to give its professional road racers a competitive edge. Driven by a desire to create lighter and faster bikes, Giant's Compact Road Design changed the look—and the performance capabilities—of competitive road bikes forever. Now, 17 years later, Compact Road Design is still the standard in high-performance bikes. The concept is simple: A toptube that slopes downward from the headtube to the seattube reduces the size of the front and rear triangles. Smaller triangles create a lighter, stiffer bike. Whatever the frame material, aluminium or composite, Compact Road Design improves the ride.
Giant’s most advanced fork steerer-tube technology. Oversized headset bearings (1 1/4-inch top and 1 1/2-inch bottom bearings) and a tapered steerer tube combine for unprecedented steering performance with no additional weight. Compared to the already stiff OverDrive system, OverDrive 2 provides up to 30 percent more torsional steering stiffness. This translates into industry-leading steering precision. Whether you’re sprinting for the finish or cornering hard in the most demanding conditions, you can ride with more power and confidence.
The proprietary “D” shaped composite seatpost dampens vibration resulting in a smooth, compliant ride.
Giant’s all-new chainstay-integrated, wireless data transmitter. The removable transmitter sends wheel-speed and cadence information directly to any ANT+ compatible computer.
