2023 Giant Reign Advanced Pro 0 M (High)

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.

Features may include:

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).

• MAESTRO SUSPENSION

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.

• ADVANCED FORGED COMPOSITE

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.

• ADJUSTABLE ENDURO GEOMETRY

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).

• REAR WHEEL SWAP

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.

• BOOST TECHNOLOGY

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.

• TRUNNION MOUNT

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.

• INTERNAL STORAGE

All new integrated down tube storage provides convenient carrying capacity for on-trail essentials.

• POWERCORE

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.

• OVERDRIVE

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.

• GIANT TUBELESS SYSTEM

Integrated Tubeless WheelSystem and tires delivers improved efficiency, comfort and control in the most user-friendly and reliable system.
