  • 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.

  • ALUXX SL Aluminum Technology

    ALUXX SL Aluminum Technology

    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.

  • Flip Chip - Maestro 3

    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.

  • Maestro Suspension Technology

    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

    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

    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.

Overview

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.


Key Performance Factors

  • 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.
