Go fast, get rowdy and nail new lines. With a full-composite chassis, developed with Giant’s enduro racing pros, this hard-charging 29/27.5’er has 160mm of Maestro rear suspension, adjustable geometry, and the option to switch to a 29-inch rear wheel.

Race-bred suspension

A Maestro rear suspension system with 160mm of travel, paired with a 170mm fork, 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

Flip chip technology lets you switch between three settings depending on the terrain. You can select a 62.47, 63.09 or 63.46- degree head angle and corresponding 77.54, 77.89 or 78.26-degree seat tube angle, resulting in a 29, 24 or 19mm 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 the stock 27.5-inch rear wheel or switch to 29. The larger 29-inch option improves stability and roll-over capabilities, while 27.5 delivers a more agile, snappier feel. It’s a quick and easy way to adjust the bike’s handling and feel.

Advanced Forged Composite Technology

Advanced Forged Composite Technology

A state-of-the-art high-pressure molding process is used to produce complex-shaped carbon fiber components that are lighter, stiffer and stronger than similar components made from aluminum. This technology is used in critical performance parts such as Maestro Suspension rocker links.

Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper for road, 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
