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.
This full-composite frame 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 wheel. 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, and new integrated down tube storage provides convenient carrying capacity for trail riding essentials.
Mainframe and rear swingarm crafted with high-performance grade raw carbon fiber and custom resin that’s custom made in Giant’s own composite factory. Handcrafted monocoque construction makes it extremely lightweight, stiff and compliant (39 percent additional rear-end stiffness over previous generation).
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.
A state-of-the-art high-pressure molding process is used to produce the carbon fiber upper rocker link that’s lighter, stiffer and stronger than aluminum.
Frame geometry can be adjusted between three settings to match riding style and 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).
Riders can choose either a 29- or 27.5-inch rear wheel, paired with a 29-inch front wheel. The stock 29-inch rear wheel optimizes stability and roll-over capabilities, while a 27.5 option delivers a more agile, snappier feel. It’s a quick and easy change to adjust the bike’s handling and feel.
Wider hub spacing (110mm front / 148mm rear) results in stiffer wheels for added control plus more tire clearance and an improved chainline for optimal drivetrain performance.
New shock mount produces a lower leverage ratio for increased pedaling and braking efficiency, plus a lower center of gravity and shorter chainstays for improved handling, climbing and agility.
All new integrated down tube storage provides convenient carrying capacity for on-trail essentials.
A massively oversized bottom bracket area features a fully integrated, 92mm wide design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Giant’s proven oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/2” lower and 1 1/8” upper) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
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.
