Giant Reign Advanced Pro 1 Mountain Bike (2023)

This all-new composite chassis is built strong, light, and fast, designed for Giant enduro pros. Its advanced suspension system has been developed, tested, and raced at the highest levels for smooth, controlled performance on the toughest trails. With enhanced adjustability, riders can fine-tune geometry and setup to tackle technical terrain exactly the way they like, delivering confidence, precision, and speed on every descent and climb.

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. Its a quick and easy change to adjust the bikes handling and feel.
