Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.

Reign Advanced Pro 29 1
2020
Go fast, get rowdy, nail new lines with total control. We took everything you love about the legendary Reign and re-imagined it for 29-inch wheels. It’s progressive, it’s confident, and it’s born to fly on aggressive enduro style terrain.
When it comes to building the ultimate enduro machine, we look to Giant Factory Off-Road Team riders who are out there pushing the limits of their bodies and bikes. This bike is for them—and for everyone else who loves to charge hard. We engineered the geometry of the Advanced composite frame and swingarm around larger diameter 29-inch wheels. That means shorter chainstays, a longer toptube, and just the right angles with the headtube (65 degrees) and seattube (76.8 degrees). Then we gave it an updated Maestro suspension system with 146mm of rear suspension. Aided by a new trunnion mount shock and Advanced Forged Composite rocker arm, we came up with a system that feels super plush, active and shreddable. Beyond that, the new Reign Advanced Pro 29 features everything you need in a pro-level enduro machine, including a cleanly routed dropper seatpost, the latest Giant WheelSystem with Boost hub spacing, and tubeless tires set up right out of the box.
Key Performance Factors
Race-bred suspension
Maestro rear suspension developed and tested under extreme conditions of Enduro World Series races. A trunnion mount shock has a longer stroke and smoother feel, and the Advanced Forged Composite upper rocker arm adds stiffness while lowering overall frame weight. The trunnion mount also allows longer dropper posts.
Progressive enduro geometry
The Advanced-grade composite 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 42/44mm 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 Composite Technology
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.
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.
