This all-new composite chassis is built strong, light and fast for Giant enduro pros. A new suspension setup has been developed, tested and raced at the highest levels. And more adjustability lets you tackle technical trails just the way you like.

  • 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.

Technologies

  • Advanced Composite Technology

    Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.

  • Advanced Forged Composite Technology

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

  • Maestro Suspension Technology

    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.

  • OverDrive

    Giant’s original oversized fork steerer tube technology. 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.

  • Tubeless System

    Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.

  • Flip Chip - Maestro 3

    This all-new technology allows riders to quickly adjust the geometry and choose a rear wheel size (29-inch or 27.5-inch) for their riding style and terrain. It’s available on select Maestro-equipped mountain bikes. The adjustment affects head tube and seat tube angles, bottom bracket height, and rear-wheel size using eccentric flip chip hardware located on the upper rocker arm of the rear suspension.
