Featuring a full-carbon frame developed by Giant’s Enduro racing professionals, theGiant Reign Advanced 1 2026 bike we’re featuring here at Escapa comes with a 160mm Maestro rear suspension, adjustable geometry, and the option to switch to a 29-inch rear wheel.
Race-Ready Suspension
A Maestro rear suspension system with 160 mm of travel, paired with a 170 mm fork, was developed and tested under the extreme conditions of the Enduro World Series races. The trunnion-mounted shock has a longer Carrera (62.5 mm compared to 60 mm on the previous generation). Additionally, the upper link made of Advanced Forged Composite adds stiffness and reduces overall weight.
Adjustable Enduro Geometry
Flip Chip technology allows you to switch between three settings depending on the terrain. You can select a head angle of 62.47, 63.09, or 63.46 degrees and the corresponding seat tube angle of 77.54, 77.89, or 78.26 degrees, resulting in a bottom bracket drop of 29, 24, or 19 mm (medium size) to precisely adjust handling based on terrain conditions, riding style, and rear wheel size.
Rear Wheel Options
Riders can choose between the standard 27.5-inch rear wheel or switch to a 29-inch wheel. The larger 29-inch option improves stability and rolling efficiency, while the 27.5-inch option offers a more agile and responsive feel. It’s a quick and easy way to adjust the bike’s handling and feel.
Advanced T-700 Carbon Technology
High-performance T-700 raw carbon fiber is used at Giant’s in-house factory to produce a custom carbon material with a high stiffness-to-weight ratio. The front triangle of these frames is assembled and molded as a single continuous piece using a patented manufacturing technique called Modified Monocoque Construction.
Advanced Forged Carbon Technology
An innovative high-pressure molding process used to produce complex-shaped carbon fiber components that are lighter, stiffer, and stronger than comparable aluminum components. This technology is used in critical high-performance parts, such as the Maestro suspension swingarm link.
Flip Chip - Maestro 3
This all-new technology allows riders to quickly adjust the geometry and choose a rear wheel size (29 inches or 27.5 inches) to suit their riding style and terrain. It is available on select Maestro-equipped mountain bikes. The adjustment affects the head tube and seat tube angles, bottom bracket height, and rear wheel size via an eccentric flip chip located on the upper rocker arm of the rear suspension.
Maestro Suspension Technology
Four strategically positioned pivot points and two Unions work together to create a single virtual pivot, resulting in the most active, efficient, and independent suspension system you’ll find on the trails.
OverDrive
Giant’s original oversized head tube technology features large 1-1/4" bottom and 1-1/8" top bearings for road bikes, and 1-1/2" bottom and 1-1/8" top bearings for mountain bikes. The tapered head tube provides greater steering control and stiffness.
