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.
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter-wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Raw ALUXX SL tubesets are further refined through a complex series of processes that provide strength (extrusion), weight reduction (butting) and shape (forming). Two key Giant technologies—FluidForming and press forming work together to eliminate gussets, improve stiffness and minimize any extra weight.
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.
ALUXX SL Aluminum
Formed from raw materials in Giant’s own forging facility, this proprietary alloy features 30 percent additional stiffness over traditional 6061-series aluminum. The increased stiffness allows engineers to use less material throughout the tubes, which results in lighter frames that never sacrifice strength or durability.
ALUMINUM ENGINEERING AT ITS VERY BEST. LIGHT, LIVELY AND PERFECTLY BALANCED BETWEEN PERFORMANCE AND COMFORT.

|Weight||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.|
