Mountain Frames

Nobody knows what you like as well as you do. When you're hurtling down the trail at high speed, everything needs to be dialed. With 165mm of rear travel, plus our Split Pivot suspension system for pedaling efficiency and consistent braking traction, Cassidy is easy-up, easy-down. Take the Cassidy Carbon Frame, hand-select your dream team of parts, and build the enduro sled you've always wanted.

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 (size - 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 and 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. - 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. - 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. - TUBELESS SYSTEM Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant's Tubeless System makes it easier than ever to experience all these benefits. - FLIP CHIP - MAESTRO The flip chip allows riders to quickly adjust the geometry of their Maestro-equipped mountain bike to better suit how and where they ride. It lets riders change the headtube/seattube angles and bottom bracket height via eccentric (offset, two-position) hardware located on the upper rocker arm.

Whether you're ripping fast flowy singletrack, putting the power down on punchy climbs, or tearing the tires off in the corners, the Optic continues to push the boundaries of what's possible on a short travel trail bike. The new Optic with 140mm/125mm of travel condenses years of technology from our long travel bikes into a lightweight package that's as ready to tear up climbs as it is tackling challenging descents. The VPSHP suspension layout provides increased rearward axle path and an idler to manage pedal feedback, keeping Optic's playful roots, while punching above its weight when the trails get rough.
