BIG HITS AND ALL-OUT DESCENTS. THIS TRAIL-CRUSHING ENDURO MACHINE FEATURES A UNIQUE PAINT TREATMENT THAT MAKES EACH BIKE ONE OF A KIND. ITS MIXED WHEEL SIZE, WITH A 29-INCH FRONT AND 27.5-INCH REAR, BLENDS STABILITY AND SPEED WITH AGILITY THAT POPS. THE GEOMETRY IS DESIGNED FOR A LONGER-TRAVEL 165MM REAR SUSPENSION SETUP AND A 180MM FORK, GIVING YOU THE UPPER HAND ON THE ROWDIEST TRAILS AND BIKE PARK TERRAIN.

Key Performance Factors

Race-bred suspension

The Maestro rear suspension eats up enduro terrain with 165mm of smooth, active rear travel matched with a 180mm travel fork. The trunnion mount rear shock has a longer stroke while the Advanced Forged Composite upper rocker arm adds stiffness and lowers overall frame weight.

Adjustable enduro geometry

A flip chip feature lets you adjust frame geometry depending on the terrain. You can select a 62.6° or 63.6° head angle and corresponding 77.4° or 77.8° degree seat tube angle, resulting in a 20 or 15mm 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 manoeuvrability to help riders rail corners, pop over features and show off their style.

TECHS & FEATURES

ALUXX SL ALUMINIUM TECHNOLOGY

This High-Performance level, state-of-the-art aluminium 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.

×

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.

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 tyres. 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

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.

WEIGHT
The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
