From Giant

The Reign platform was initially introduced in 2005 as one of the first Giant mountain bikes to feature Maestro suspension. A lot has changed in the nearly two decades since, and Reign has continually evolved with the times. From suspension technologies to wheel sizes, frame materials to geometries, it’s a bike that has been pushing the boundaries of trail riding progression since before modern enduro racing even existed. It has racing in its DNA, but is equally at home in the bike park or on backcountry rides.

The new Reign Advanced Pro and Reign series allow riders to choose 29-inch wheels front and rear, which is how they arrive from the factory, or swap out the rear for a 27.5-inch wheel. (The Reign SX must be ridden in the 29-inch front and 27.5-inch rear wheel configuration.) And the new range offers even greater adjustability with three flip chip settings to dial in frame geometry including head and seat tube angles, along with the bottom bracket drop.


With enduro racers and trail riders continuing to push their limits on aggressive terrain, the demands on bikes and gear are higher than ever. Steeper descents, bigger drops, higher speeds through rocks, roots and ruts. The new Reign range gives riders an edge with more capable suspension performance front and rear.

It starts with a new Maestro rear suspension system found on the Reign Advanced Pro and Reign series, which now has 160mm of travel, an additional 14mm over the previous generation. The trunnion mount shock has a longer stroke for a smooth, active feel on a variety of terrain. The Advanced Forged Composite upper rocker arm adds stiffness to the system, which improves the bike’s handling while cornering, accelerating or bombing down through chunky terrain.

Up front, both the Reign Advanced Pro and Reign now come with a 170mm fork to help gobble up trail impacts and improve control. The Reign SX, also featuring Maestro rear suspension, is an ideal choice for bike parks and gravity-focused riders. It now has more travel, with 165mm in the rear and a beefy 190mm dual crown suspension fork up front.


The new Reign Advanced Pro and Reign chassis are engineered with all-new geometry that gives racers the quickness and control they need to shave seconds off their runs. At the same time, both series offer everyday riders the stability and confidence to elevate their skills on more challenging terrain.

The new frames are designed with a lower standover height. Combined with a long reach, this makes it easier to maneuver the bike. From low-speed cornering on tight, technical terrain to high-flying jumps at the bike park, the new geometry makes it easier to change lines, hop over obstacles and stay in control.


The new flip chip setup offers the option to use a 27.5-inch rear wheel (paired with a 29-inch front wheel), which gives the bike more saddle-to-tire clearance in the rear. Some riders prefer this mullet setup for steep, technical terrain.

Using the stock 29-inch rear wheel optimizes stability and roll-over capabilities, while the 27.5-inch option delivers a more agile, snappier feel. It’s a quick and easy change to adjust the bike’s handling and feel.


A new three-position flip chip lets you adjust the geometry to suit your riding style and terrain. It offers bottom bracket drop adjustments in 5mm increments (35, 30 or 25mm) and also lets you change the head tube angle (63.5. 63.9 or 64.2 degrees) and seat tube angle (78.3, 78.7 or 79 degrees).

The high position of the flip chip increases ground clearance, a good option for tighter, more technical terrain. In this position, the steeper seat tube angle helps you power up climbs. Put the flip chip into the low position, and the head tube gets slacker and the bottom bracket drops. This gives the bike more confident handling at higher speeds. For those who want a more neutral setup, the middle position is a versatile option.
