Big hits and all-out descents. This trail-crushing enduro machine delivers confidence and control for the rowdiest terrain. Its mixed wheel size, with a 29-inch front and 27.5-inch rear, blends stability and speed with agility that pops.

- Race-bred suspension
Maestro rear suspension eats up enduro terrain with 165mm of smooth, active rear travel matched with a 190mm travel fork. The trunnion mount rear shock has a longer stroke (65mm over 60mm on the previous generation) while the Advanced Forged Composite upp

- Adjustable enduro geometry
Flip chip adjustability lets you switch between two settings depending on the terrain. You can select a 63.1 or 63.5-degree head angle and corresponding 77.9 or 78.3-degree seat tube angle, resulting in a 25 or 19mm bottom bracket drop (size medium) to fi

- Mixed wheel size
A 29-inch front wheel provides speed, stability and front-end control on rough, technical trails. A 27.5-inch rear wheel adds agility and maneuverability to help riders rail corners, pop over features and show off their style.

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.

This High-Performance level, state-of-the-art aluminum material is made predominantly from 6011 alloy and delivers best-in-class strength-to-weight ratios. These framesets also feature unique welding technologies for a high-performance ride quality.

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.

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.

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.

The flip chip allows riders to quickly adjust the geometry of their Maestro-equipped mountain bike to better suit how and where they ride. It lets riders change the headtube/seattube angles and bottom bracket height via eccentric (offset, two-position) hardware located on the upper rocker arm.
