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. FEATURES: 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.
