PUSH NEW LIMITS ON CHALLENGING TERRAIN. THIS ENDURO RIPPER HAS 160MM OF REAR SUSPENSION THAT EATS UP ROCKS, DROPS AND WHATEVER COMES YOUR WAY. A THREE-POSITION FLIP CHIP LETS YOU ADJUST GEOMETRY AND SWITCH OUT THE REAR WHEEL FROM 27.5-INCH TO 29.

KEY PERFORMANCE FACTORS

Race-bred suspension

A Maestro rear suspension system with 160mm of travel was developed and tested under the extreme conditions of Enduro World Series races. The trunnion mount shock has a longer stroke (62.5mm compared to 60mm on the previous generation). And the Advanced Forged Composite upper rocker arm adds stiffness and lowers overall weight.

Adjustable enduro geometry

Flip chip technology lets you switch between three settings depending on the terrain. You can select a 62.5, 63 or 63.5-degree head angle and corresponding 77.5, 77.9 or 78.3-degree seat tube angle, resulting in a 29, 24 or 19mm bottom bracket drop (size medium) to fine-tune handling for trail conditions, riding style and rear-wheel size.

Rear wheel options

Riders can choose either the stock 27.5-inch rear wheel or switch to 29. The larger 29-inch option improves stability and roll-over capabilities, while the 27.5 option delivers a more agile, snappier feel. It’s a quick and easy way to adjust the bike’s handling and feel.

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.

×

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.

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.

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.
