Reign Advanced Pro 2
A new Maestro rear suspension system with longer travel (160mm) was developed and tested under the extreme conditions of Enduro World Series races. The trunnion mount shock has a longer stroke (62.5mm compared to 60mm on the previous generation). And the Advanced Forged Composite upper rocker arm adds stiffness and lowers overall weight.
New flip chip technology lets you switch between three settings depending on the terrain. You can select a 63.5, 63.9 or 64.2-degree head angle and corresponding 78.3, 78.7 or 79-degree seat tube angle, resulting in a 35, 30 or 25mm bottom bracket drop (size medium) to fine-tune handling for trail conditions, riding style and rear-wheel size.
Riders can choose either a 29- or 27.5-inch rear wheel, paired with a 29-inch front wheel. The larger 29-inch option improves stability and roll-over capabilities, while the 27.5 option delivers a more agile, snappier feel. It’s a quick and easy change to adjust the bike’s handling and feel.
This full-composite frameset is engineered with enduro racing geometry and adjustability that lets you change the bike’s handling and riding characteristics with three flip chip settings. Also new is the ability to swap out the stock 29-inch rear wheel for a smaller 27.5-inch one. This “mullet” setup makes for an equally short chainstay length and a shorter reach, giving the bike a snappier feel on aggressive terrain. The updated Maestro suspension system has 160mm of rear wheel travel, paired with a 170mm fork up front. And new integrated down tube storage provides convenient carrying capacity for trail riding essentials.
Mainframe and rear swingarm crafted with high-performance grade raw carbon fiber and custom resin that’s custom made in Giant’s own composite factory. Handcrafted monocoque construction makes it extremely lightweight, stiff and compliant (39 percent additional rear-end stiffness over previous generation).
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.
A state-of-the-art high-pressure molding process is used to produce the carbon fiber upper rocker link that’s lighter, stiffer and stronger than aluminum.
Frame geometry can be adjusted between three settings to match riding style and terrain. You can select a 63.5, 63.9 or 64.2-degree head angle and corresponding 78.3, 78.7 or 79-degree seat tube angle, resulting in a 35, 30 or 25mm bottom bracket drop (size medium).
Riders can choose either a 29- or 27.5-inch rear wheel, paired with a 29-inch front wheel. The stock 29-inch rear wheel optimizes stability and roll-over capabilities, while a 27.5 option delivers a more agile, snappier feel. It’s a quick and easy change to adjust the bike’s handling and feel.
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.
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.
All new integrated down tube storage provides convenient carrying capacity for on-trail essentials.
A massively oversized bottom bracket area features a fully integrated, 92mm wide design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Giant’s proven 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) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
Integrated Tubeless WheelSystem and tires delivers improved efficiency, comfort and control in the most user-friendly and reliable system.
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.
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.
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.
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.
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.
This all-new technology allows riders to quickly adjust the geometry and choose a rear wheel size (29-inch or 27.5-inch) for their riding style and terrain. It’s available on select Maestro-equipped mountain bikes. The adjustment affects head tube and seat tube angles, bottom bracket height, and rear-wheel size using eccentric flip chip hardware located on the upper rocker arm of the rear suspension.
