Giant Reign Advanced Pro 0 Dual Suspension Mountain Bike (2023)
This all-new composite chassis is engineered to be strong, light, and fast — the ultimate choice for Giant’s enduro pros. Featuring a newly developed suspension system that’s been tested and raced at the highest levels, it delivers unmatched performance and control on demanding terrain. With increased adjustability, you can fine-tune your setup to handle technical trails exactly the way you like, from steep descents to rough climbs. Built for speed, precision, and confidence on every ride.
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.
