Lightweight efficiency Advanced composite frame and Advanced SL composite fork save a combined 200 grams compared to previous generation. Updated geometry includes a lower bottom bracket, longer reach, and steeper head tube angle for improved acceleration and climbing. Tuned compliance A lowered seatstay junction with smaller diameter tubes absorbs road shocks and vibrations. The Contact SLR XR D-Fuse carbon handlebar and D-Fuse seatpost work as a system to optimise compliance without sacrificing stiffness while cornering, sprinting and 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 tyres up to 53mm. You can choose the included D-Fuse SLR composite seatpost for maximum compliance, or switch to a 30.9mm round or dropper post.Fast gravel is fun gravel.
