Reign 29er 2

Rock the mullet style or go all in on 29. Either way, this new enduro ripper is made to push limits on hard-charging terrain. Updated suspension eats up rocks, drops and whatever the trail throws your way. And a three-position flip chip lets you adjust all the angles to dial it in just right.

Advanced Composite Technology

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.

highlights

The geometry of the ALUXX SL aluminum frameset has been updated to accommodate 29-inch wheels, and you now have the option to run a “mullet” setup with a 27.5 rear wheel. This translates into a short chainstay length, a shorter reach, and geometry that can be adjusted via a three-position flip chip. An updated Maestro suspension system delivers 160mm of rear wheel travel mated to a 170mm fork. And new integrated down tube storage provides convenient carrying capacity for trail riding essentials.

KEY PERFORMANCE FACTORS

Race-bred suspension

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.

Adjustable enduro geometry

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.

Rear wheel options

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.

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.
