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 upper rocker arm adds stiffness and lowers overall frame weight.

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 fine-tune handling for varying trail conditions and riding style.

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.

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.

More Info

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.
