Washboard descents, sketchy dirt, gravel and rocks of all shapes and sizes. You never know what you'll get on a gravel ride. This new Revolt with front suspension helps you float through it all with speed and control. KEY PERFORMANCE FACTORS Smooth control Composite frameset is designed specifically for front suspension. With 40mm of travel, the fork absorbs bumps and impacts so you can ride smoother and faster over rugged gravel and dirt. Tuned compliance Lowered seatstays with smaller diameter tubes absorb road shocks and vibrations. A Contact SL XR D-Fuse handlebar adds more compliance without sacrificing the stiffness needed for cornering, sprinting or climbing. Adaptable to the terrain A flip chip on the rear dropout adjusts the wheelbase: short for quicker handling, or long for improved stability at speed. The long setting also allows for larger diameter tires up to 53mm. You can use the included dropper/suspension seatpost for added capabilities, or switch to a proprietary D-Fuse seatpost or traditional 30.9mm round seatpost. HIGHLIGHTS The Advanced composite frameset is designed with suspension-optimized geometry and paired with a 40mm travel fork, delivering a smooth, controlled ride quality on rugged gravel and dirt. A flip chip on the rear dropout lets you adjust the wheelbase and increase tire clearance up to 53mm. You can use the included dropper post, switch to a proprietary Giant D-Fuse seatpost for added compliance, or use a standard 30.9mm round seatpost. A Contact SL XR D-Fuse handlebar further minimizes fatigue by absorbing shocks and vibrations. ADVANCED COMPOSITE - High-performance grade raw carbon material is used to produce this custom frame material with a high stiffness-to-weight ratio. The front triangle is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction. SUSPENSION FORK - 40mm of front travel expands this bike's capabilities, improving control and reducing fatigue while riding rough roads, gravel and dirt. FLIP CHIP DROPOUT - Geometry, wheelbase and rear tire clearance can be adjusted using two-position hardware in the rear dropouts. A longer wheelbase adds stability and increases tire clearance (up to 53mm), while a shorter wheelbase delivers a quicker, more agile ride. COMPACT ROAD - A downward sloping top tube (from the head tube to the seat tube) creates smaller front and rear triangles for a lighter, stiffer bike. It also makes it easier for riders of all sizes to have a perfect fit. D-FUSE TECHNOLOGY - Proprietary D-shaped handlebar works to dampen vibrations and absorb road shock, resulting in a smooth, compliant ride quality. SEATPOST ADAPTOR - New frame design allows you to use the stock dropper seatpost, a proprietary D-Fuse seatpost, or a traditional round 30.9mm seatpost. This lets riders choose the right seatpost for their riding style and terrain. GIANT TUBELESS SYSTEM - Integrated Tubeless WheelSystem and tires deliver improved efficiency, comfort and control in the most user-friendly and reliable system. DISC-BRAKE INTEGRATION - The frame and fork are engineered specifically for disc brakes, producing reliable braking performance in all weather and road conditions. OVERDRIVE - Designed for precise steering performance, this system's oversized headset bearings (1 1/4" lower and 1 1/8" upper) and tapered steerer tube work together to provide optimal steering stiffness and control. MEGADRIVE - A massive rectangular down tube and oversized top tube provide superior lateral and torsional steering precision. The precisely engineered, rectangular shaped down tube yields unprecedented steering and pedaling stiffness. POWERCORE - A massively oversized bottom bracket area features a fully integrated 86mm wide design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.

Straggler is a bikepacking-inspired road/gravel bike mostly at home on pavement but ready for trail duty when called. Born on Gravel. Raised on Pavement Straggler is tuned for cross-over exploration on a wide variety of terrain conditions. It's a day-tripper and a weekender. It's a "rough road" road bike, a cyclocross bike with no pretense about racing, a utilitarian townie, a light-duty touring bike and an all-weather commuter.
