Designed with purpose
- Lefty Suspension® For over 20 years, Lefty has been smoother, stiffer, and more precise than anything else out there. When it comes to suspension performance, Lefty stands alone.
- SmartSense™ SmartSense is Cannondale’s unique, discrete, and fully-integrated ecosystem of on-bike lights, rear-facing radar, sensors, and connected smartphone app. Designed to enhance visibility and awareness for you and other road-users alike, it’s the clever companion that inspires you to ride more, and with more confidence.
- HeadShok™ Urban front suspension that’s head and shoulders above the rest. HeadShok delivers more comfort and control, with less weight, less wear, and less maintenance than conventional forks.
- Delta Steerer Delta is an innovative steerer tube design that’s exclusive to Cannondale. The unique v-shape enables cables to be routed internally while minimizing the headtube’s frontal area, resulting in sleeker looks and less aero drag than other internally-routed road and gravel bikes.
