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.

Key Performance Factors

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.

  • 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.
