  • 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.

    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.
