Superior engineering for a silky smooth ride. Maximize your performance on your longest, hardest road rides. Engineered for real-world performance, especially on challenging roads and long days in the saddle. The Advanced-grade composite frame features endurance geometry with the perfect blend of light weight, stiffness and road-smoothing compliance. The OverDrive 2 steerer tube and full composite fork work together to boost front-end stiffness and precision. Disc brake technology with 12mm front and rear thru-axles gives you total control, even on rough roads and poor conditions. The D-Fuse seatpost smoothes out road vibrations, and the PowerCore bottom bracket turns every pedal stroke into positive forward motion.
