Why buy bike from us?


This lightweight Advanced-grade composite frame delivers the perfect blend of stiffness and compliance. It’s engineered with endurance geometry, giving you a smooth ride quality that minimizes fatigue on your longest, hardest rides. Integrated flat-mount disc-brake technology with 12mm thru-axles front and rear gives you added control on rough roads in all types of weather. And the vibration-damping D-Fuse seatpost absorbs road vibrations to give you an even smoother, quieter ride without adding any weight. Tubeless Ready.

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.

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.

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.

D-Fuse Seatpost

The proprietary “D” shaped composite seatpost damps vibration, resulting in a smooth, compliant ride.


Giant’s chainstay integrated, wireless data transmitter. The removable transmitter sends wheel speed and cadence information directly to any ANT+ compatible computer.
