Choose your line and let ’er rip. From chunky alpine terrain to warp-speed park runs, this 29er eats up rugged terrain. Its smooth Maestro rear suspension and beefy 170mm fork help keep you in control no matter what comes your way.
This all-new full-suspension 29er features a new ALUXX SL frameset, our latest Maestro rear suspension, and components that are aimed at technical descents. It’s engineered with progressive geometry that’s optimized for its 29-inch wheels. That means shorter chainstays, a longer toptube, and headtube/seattube angles that put you in the perfect position to slay all types of singletrack. The rear suspension gives you 146mm of smooth, active rear travel with a new trunnion mount shock and Advanced Forged Composite rocker arm. And this SX model features a longer travel 170mm fork for even more control on high-speed descents. Add in a host of other aggressive trail riding technologies, including a cleanly routed dropper seatpost, the latest Giant WheelSystem with Boost hub spacing, and tubeless tires set up right out of the box, and it’s ready to rip when you are.
Key Performance Factors
Race-bred suspension
Maestro rear suspension and a longer travel 170mm fork developed and tested in Enduro World Series races. The trunnion mount rear shock has a longer stroke and smoother feel, and Advanced Forged Composite upper rocker arm adds stiffness while lowering overall frame weight.
Progressive enduro geometry
The frameset features updated enduro-style geometry, so you can ride aggressive descents and rail corners with confidence. The 65/76.8-degree headtube/seattube angles with a 44mm fork offset produce confident front-end handling with high-speed stability and control.
29er confidence and control
Larger 29-inch diameter wheels roll over rugged enduro terrain with improved balance and stability, giving you the momentum to crank up tough climbs and the confidence to fly on fast, technical descents.
Techs & Features
Advanced Forged Composite Technology
A state-of-the-art high-pressure molding process is used to produce complex-shaped carbon fiber components that are lighter, stiffer and stronger than similar components made from aluminum. This technology is used in critical performance parts such as Maestro Suspension rocker links.
ALUXX SL Aluminum Technology
This High-Performance level, state-of-the-art aluminum material is made predominantly from 6011 alloy and delivers best-in-class strength-to-weight ratios. These framesets also feature unique welding technologies for a high-performance ride quality.
Maestro Suspension Technology
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.
Tubeless System
Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
