AWARD-WINNING BIKES
Techs & Features

This Performance level frame material features 6061 alloy with single-butted tubes to produce strong, lightweight framesets for a variety of different bikes and riding styles.

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.

The D-Fuse seatpost and handlebar were designed to function as a system, absorbing road shocks and vibrations so you can ride farther, faster.

Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper for road, 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.

- WeightThe most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
