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 work in conjunction to provide optimal steering stiffness.

PowerCore

A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimetre-wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.

Gussett Free Design

Most of Giant’s competitors use old-fashioned gussets, additional pieces of material that are welded to the outside of a tube junction to provide additional support. Giant pioneered and perfected the use of radically shaped tubesets that provide all the strength and stability of gusseted tubes without added material and welds.

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