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 160g compared to the 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. 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. 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. 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. D-Fuse Technology The D-Fuse seatpost and handlebar were designed to function as a system absorbing road shocks and vibrations so you can ride farther faster.
