Dial in the frame geometry for your riding style and terrain, then let it rip. This new shapeshifter enduro bike delivers confidence and control on the rowdiest terrain. Its mixed wheel size, 29-inch front and 27.5 rear, blends stability and speed with agility that pops.

Key Performance Factors

Race-bred suspension

The 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

New flip chip feature lets you adjust frame geometry 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.

Highlights

This gravity-focused enduro machine features a lightweight, stiff and super-strong ALUXX SL frameset paired with our latest Maestro rear suspension. The frameset is optimized for its mixed wheel setup, with a 27.5-inch rear and 29-inch front. A plush suspension system with 165mm in the rear and a 190mm triple crown fork up front gives you the ability to send it on the roughest descents. You can also adjust frame geometry with a flip chip that lets you switch the head tube and seat tube angles, along with bottom bracket drop, to dial in the handling for your riding style and terrain. And a new integrated down tube storage feature provides convenient carrying capacity for on-trail essentials.

Techs & Features

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

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

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

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.

PowerCore

A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design (92-millimeter wide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.

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.
