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.
Reign SX 29
Reign Supreme
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.
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.
Highlights
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.

ALUXX SL-Grade Aluminum Frame
High-performance level, state-of-the-art aluminum material is made predominantly of 6061 alloy and delivers best-in-class strength-to-weight ratio. These framesets also feature unique welding technologies for a high-performance ride quality.
3
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.
4
29-Specific Enduro Geometry
Updated “long and low” enduro-frame geometry with 64/75.8-degree headtube/seattube angles for aggressive handling is tailored for 29-inch wheels to optimize roll-over capabilities and high-speed momentum.
5
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.
6
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.
7
MegaDrive
A massive rectangular downtube and oversized toptube work in unison to provide superior front end lateral and torsional steering precision. The precisely engineered, rectangular shaped downtube yields unprecedented steering and pedaling stiffness.
8
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 92-millimeter wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
9
OverDrive
Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
10
Giant Tubeless System
Integrated Tubeless WheelSystem and tires deliver improved efficiency, comfort and control in the most user-friendly and reliable system.

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.
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design (92-millimeter wide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
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.
