Mountain Frames

Techs & Features: Advanced Composite Technology Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction. Advanced Forged Composite Technology A state-of-the-art high-pressure molding process is used to produce complex-shaped carbon fiber components that are lighter, stiffer and stronger than similar components made from aluminum. This technology is used in critical performance parts such as Maestro Suspension rocker links. FlexPoint Pro Suspension Technology Developed as a superlight rear suspension setup for XC bikes that demand efficiency, control and responsive handling, FlexPoint Pro is a linkage-driven, single-pivot system that delivers 100mm of rear-wheel travel. It’s engineered with a full-composite swingarm that significantly reduces overall frame weight.

GO FAST, GET ROWDY AND NAIL NEW LINES. WITH A FULL-COMPOSITE CHASSIS, DEVELOPED WITH GIANT’S ENDURO RACING PROS, THIS HARD-CHARGING 29ER HAS 160MM OF MAESTRO REAR SUSPENSION, ADJUSTABLE GEOMETRY, AND THE OPTION TO SWITCH TO A 27.5-INCH REAR WHEEL. Key Performance Factors Race-bred suspension A Maestro rear suspension system with 160mm of travel, paired with a 170mm fork, 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 gene Adjustable enduro geometry 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 Rear wheel options Riders can choose either the stock 29-inch rear wheel or switch to 27.5. The larger 29-inch option improves stability and roll-over capabilities, while 27.5 delivers a more agile, snappier feel. It’s a quick and easy way to adjust the bike’s handling

Techs & Features: Advanced SL Composite Technology Professional Grade raw carbon fiber is woven in our composite factory to produce our lightest, stiffest, and highest-quality frames. This is the technology used by Giant’s pro racers in almost every cycling discipline. OverDrive 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.

See You At The Bottom Even though Jekyll boasts a unique combo of go-fast tech that's never been seen before, it's not a bike that talks. It's a bike that goes. Where it thrives Steep, fast, rowdy mountains What it's built for Enduro racing, bike park sessions, high-speed mobbing Highlights - Full carbon frame, 165mm travel, Proportional Response Tuned - Fox Float Factory X2 Shock - Guidler-Idler pulley/chainguide system Descend into Greatness It's a hell of a climber but come on. Jekyll was born for the downs. Every part of it crafted for the sweet embrace of speed, every element designed to help you wring a bit more of velocity's nectar from those steep, chunky, high pucker lines you love. Best. Suspension. Ever. 4-bar meets high pivot meets idler pulley meets size-specific kinematics. For real. If you're not up for suspension buzzword bingo, just know that it grips, floats, and pedals like nothing else. It's always up for getting down. The Gravity Cavity The shock tucks cleanly into the twin spar downtube, keeping the bike's center of gravity as low as possible. Wicked stability, instant line changes and one-of-a-kind looks. Built for You Well, not you specifically. But someone just like you. With our Proportional Response design, everything—from the suspension layout to the geometry, even the length of the chainstays—is completely customized by size, for performance built just for you. Suspension Like No Other High main pivot gives it a bump-swallowing rearward axle path. The Guidler pulley kills the pedal kickback of high pivot systems. The 4-bar linkage keeps braking smooth, traction high and pedaling crisp. Guidler Idler pulley + chainguide = Guidler. Clever, right? Idler eliminates feedback from the high pivot swingarm, keeping your pedal stroke smooth, even when the terrain isn't. The guide, well, it guides. Suspension Built For You A rider's center of gravity drives how the suspension performs, yet most bikes use the exact same layout for all sizes. Proportional Response Suspension alters the design by size for truly next-level performance. Proportional Response Geometry Long, slack and low—and fully size-specific. As the front of the bike gets longer with each size, the chain stay length increases proportionally, keeping the rider centered between the wheels for true "made for you" handling. Guardhouse Downtube protector keeps your frame safe from roost and strikes, while letting water and debris pass through. The Ai Advantage Our Ai Offset Drivetrain delivers more tire and mud clearance in the swingarm, and more even spoke angles for a stiffer, stronger rear wheel.
