Road Bikes

ROUGH ROADS, GRAVEL OR DIRT. HOWEVER YOU CHOOSE TO ROLL, THIS BIKE DOES IT ALL. THE LIGHTWEIGHT, SMOOTH-RIDING COMPOSITE FRAMESET AND ADJUSTABLE WHEELBASE MAKE IT MORE CAPABLE THAN EVER. KEY PERFORMANCE FACTORS Fast and light Advanced composite frame and fork save more than 160 grams compared to previous model. Updated geometry includes a lower bottom bracket, longer reach and steeper head tube angle for improved acceleration and climbing. Tuned compliance Dropped seatstays with thin tubing absorbs road shocks and vibrations. D-Fuse handlebar and seatpost work as a system to add compliance without sacrificing stiffness while 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 allows for larger diameter tires up to 53mm. You can also choose the included D-Fuse seatpost for maximum compliance, or switch to a 30.9mm round or dropper post.

GUNNING FOR THE RACE WIN OR DIGGING DEEP FOR A PR, THIS COMPOSITE ROAD RACING BIKE GIVES YOU THE SPEED, EFFICIENCY AND CONTROL TO PUSH IT TO THE LIMIT, AND THEN A LITTLE BIT MORE. KEY PERFORMANCE FACTORS Class-leading efficiency Combining best-in-class stiffness-to-weight with strategically placed aero-tube shaping, this frameset is engineered for faster climbing, explosive acceleration, and unyielding pedaling stiffness for race-winning performance. Advanced aerodynamics This is where the TCR’s most quantifiable gains can be found compared to previous-generation models. Every tube shape was analyzed, engineered and tested to create an overall structure with significantly lower drag at a wider range of yaw angles. Total control Integrated disc brakes deliver smooth, powerful stopping power and modulation for added control in variable weather and road conditions. Flat mounts and new thru-axles boost stiffness and improve overall handling, while added frame and fork clearance allows for larger diameter tires up to 32mm. 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. 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. COMPACT ROAD DESIGN Introduced by Giant with the professional Team ONCE in the 1990s, Compact Road revolutionized the look and feel of high-performance road bikes forever. A downward-sloping toptube (from the headtube to the seattube) 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. 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.

Which to choose: speed or storage space? You can have both with a Hook. With an able steel frame and carbon fork, this bike is fast and versatile. Size-matched 650B or 700C wheels across the sizes provide control and comfort, while the Shimano GRX groupset and double crankset give you a close ratio with a broad range of gears. Take your pick from a range of fixing points, including a direct mount for a top tube bag, triple cage mounts, rear rack and fender. Or, leave it stripped back and fly. The Hook might have been designed as a gravel racer, but that doesn’t stop it from also being a perfect tourer, commuter, or even summer-season crossbike.

Tom Ritchey rides about 10,000 miles per year, and he loves those long boundless rides where the surface changes from gravel to tarmac and everything in between. Combine that with his more than 40 years of designing and building bicycles, and it’s no wonder the Outback has become an icon in the gritty world of gravel and adventure bikes.
