Reign SX 29

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.

  • 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 our bikes are designed for best-in-class weight and ride quality.
