This state-of-the-art aluminum material is made predominantly from 6011 alloy and delivers best-in-class strength-to-weight ratios. The frameset features unique welding technologies for a high-performance ride quality.

Highlights
The geometry of the ALUXX SL aluminum frameset has been updated to accommodate 29-inch wheels, and you now have the option to run a “mullet” setup with a 27.5 rear wheel. This translates into a short chainstay length, a shorter reach, and geometry that can be adjusted via a three-position flip chip. An updated Maestro suspension system delivers 160mm of rear wheel travel mated to a 170mm fork. And new integrated down tube storage provides convenient carrying capacity for trail riding essentials.

Aluxx SL Aluminum
Maestro Suspension
Four strategically positioned pivot points and two linkages all work together to create a single floating pivot for the most active, efficient and independent suspension system on the trail.
Advanced Forged Composite
A state-of-the-art high-pressure molding process is used to produce the carbon fiber upper rocker link that’s lighter, stiffer and stronger than aluminum.
Adjustable Enduro Geometry
Frame geometry can be adjusted between three settings to match riding style and terrain. You can select a 63.5, 63.9 or 64.2-degree head angle and corresponding 78.3, 78.7 or 79-degree seat tube angle, resulting in a 35, 30 or 25mm bottom bracket drop (size medium).
Rear Wheel Swap
Riders can choose either a 29- or 27.5-inch rear wheel, paired with a 29-inch front wheel. The stock 29-inch rear wheel optimizes stability and roll-over capabilities, while a 27.5 option delivers a more agile, snappier feel. It’s a quick and easy change to adjust the bike’s handling and feel.
Boost Technology
Wider hub spacing (110mm front / 148mm rear) results in stiffer wheels for added control plus more tire clearance and an improved chainline for optimal drivetrain performance.
Trunnion Mount
New shock mount produces a lower leverage ratio for increased pedaling and braking efficiency, plus a lower center of gravity and shorter chainstays for improved handling, climbing and agility.
Internal Storage
All new integrated down tube storage provides convenient carrying capacity for on-trail essentials.
PowerCore
A massively oversized bottom bracket area features a fully integrated, 92mm wide design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
OverDrive
Giant’s proven oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/2” lower and 1 1/8” upper) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
Giant Tubeless System
Integrated Tubeless WheelSystem and tires delivers improved efficiency, comfort and control in the most user-friendly and reliable system.

ALUXX SL Aluminium Technology
Flip Chip - Maestro 3
This all-new technology allows riders to quickly adjust the geometry and choose a rear wheel size (29-inch or 27.5-inch) for their riding style and terrain. It’s available on select Maestro-equipped mountain bikes. The adjustment affects head tube and seat tube angles, bottom bracket height, and rear-wheel size using eccentric flip chip hardware located on the upper rocker arm of the rear suspension.

Four strategically positioned pivot points and two linkages all work together to create a single floating pivot for the most active, efficient and independent suspension system on the trail.
OverDrive
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.
