Vikt The 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 Giant bikes are designed for best-in-class weight and ride quality.

Giant Overdrive 2/Overdrive
As the first manufacturer to bring the tapered headtube to market—with the 2006 Glory mountain bike—Giant knows a thing or two about inventing solutions for improved steering precision. The original OverDrive technology resulted in groundbreaking stiffness-to-weight ratios, and the newer OverDrive 2 system on high-performance road and mountain bikes offers even further advantages.
Giant Overdrive 2
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.
>1 1/4-inch top bearing
>1 ½-inch bottom bearing
>1 1/4 –inch stem

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.
Giant’s original oversized fork steerer-tube technology. Designed to provide solid front-end steering performance, the system’s oversized headset bearings and tapered steerer tube provide optimal steering stiffness. Road models feature 1 1/8-inch top and 1 1/4-inch bottom bearings, while the mountain version features 1 1/8-inch top and 1 1/2-inch bottom bearings.
OverDrive provides up to 15 percent more torsional steering stiffness than straight steerer-tube designs. This translates into much more accurate steering input from a rider’s hands, through the handlebar and stem, and down to the front wheel. Whether hammering uphill or carving through a corner, OverDrive transmits input directly to the front wheel for more precise handling.
Giant D-Fuse seatpost
The proprietary “D” shaped composite seatpost dampens vibration; resulting in a smooth, compliant ride.
Giant Compact Road Design
n 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, aluminum or composite, Compact Road Design improves the ride. Here's how:
Compact Road’s most distinctive feature, the downward-sloping toptube, results in smaller front and rear triangles on the frame. Because the triangles are smaller, less material is needed. Less material equals less weight.
Picture two triangles made from equal diameter tubing. The smaller, more compact triangle uses shorter tubes. The larger triangle requires longer tubes. It’s easy to see which is more structurally sound—the smaller triangle is stiffer, less susceptible to flexing and twisting. And on a performance road frame, stiffer is faster.
With traditional geometry, builders increase stiffness by using stiffer material. That might help you sprint faster but it also makes for a less comfortable ride. With Compact Road, Giant engineers are able to design frames with just the right amount of vertical compliance. You get a smoother, more comfortable ride.
Because of the sloping toptube and lower standover height, it’s easier for riders of all sizes to get the perfect fit. With greater adjustability and up to six sizes per series, even Giant’s most demanding pro athletes, women and men of all different heights, always have a perfect fit with stock-size frames.
The Aluxx advantage
From the manipulation of atomic grain structures to our advanced forming and welding techniques, Giant has been at the forefront of aluminum engineering for more than 30 years. Today, ALUXX Aluminum Technology represents the pinnacle of alloy performance. A heritage of craftsmanship combined with unmatched manufacturing capabilities gives Giant the unique ability to monitor every step of the aluminum frame-building process. Through our cutting-edge materials science, proprietary forming techniques, and attention to detail, we are constantly advancing aluminum performance to create bikes that are lighter, stronger and stiffer. The difference can be felt in the ride. Every aluminum bike bearing the ALUXX Aluminum Technology label must live up to the highest standards and meet the tightest tolerances of any aluminum frame in the world.
