Choose your line and let it 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 29er features a lightweight, stiff and super-strong ALUXX SL frameset with our latest Maestro rear suspension. The components have been hand-picked to excel on technical descents. The frameset is engineered with progressive geometry including shorter chainstays, a longer toptube, and headtube/seattube angles that put you in the perfect position to slay singletrack. The rear suspension gives you 146mm of smooth, active rear travel with a new trunnion mount shock and Advanced Forged Composite rocker arm. This SX model features a 170mm fork for outstanding control on high-speed descents. Add in a host of other aggressive trail riding technologies, including a cleanly routed dropper seatpost and the latest Giant WheelSystem with Boost hub spacing and tubeless tires, and it’s ready to rip when you are.
KEY PERFORMANCE FACTORS
Race-bred suspension
Maestro rear suspension and a 170mm fork developed and tested in Enduro World Series races. The trunnion mount rear shock has a longer stroke and smoother feel, and an Advanced Forged Composite upper rocker arm adds stiffness while lowering overall frame weight.
Progressive enduro geometry
The frameset features enduro-ready geometry so you can ride aggressive descents and rail corners with confidence. The 64.56/76.36-degree headtube/seattube angles with a 42mm 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.
