Details

THIS ALL-NEW COMPOSITE CHASSIS IS BUILT STRONG, LIGHT AND FAST FOR GIANT ENDURO PROS. A NEW SUSPENSION SETUP BEEN DEVELOPED, TESTED AND RACED AT THE HIGHEST LEVELS. AND MORE ADJUSTABILITY LETS YOU TACKLE TECHNICAL TRAILS JUST THE WAY YOU LIKE.

KEY PERFORMANCE FACTORS
Race-bred suspension
A new Maestro rear suspension system with longer travel (160mm) 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
New flip chip technology lets you switch between three settings depending on the terrain. You can select a 63.5, 63.9 or 64.2-degree head angle and corresponding 78.3, 78.7 or 79-degree seat tube angle, resulting in a 35, 30 or 25mm 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 a 29- or 27.5-inch rear wheel, paired with a 29-inch front wheel. 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 change to adjust the bike's handling and feel.

HIGHLIGHTS
This full-composite frameset is engineered with enduro racing geometry and adjustability that lets you change the bike's handling and riding characteristics with three flip chip settings. Also new is the ability to swap out the stock 29-inch rear wheel for a smaller 27.5-inch one. This “mullet” setup makes for an equally short chainstay length and a shorter reach, giving the bike a snappier feel on aggressive terrain. The updated Maestro suspension system has 160mm of rear wheel travel, paired with a 170mm fork up front. And new integrated down tube storage provides convenient carrying capacity for trail riding essentials.
