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.
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.
OVERDRIVE
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.
