The headlight is small yet powerful, turning night into day with up to 800 lumens. A daylight function keeps you safe, while its stem-mounted design keeps the cockpit clean.
The rear radar watches your back, alerting you to approaching vehicles so you can ride with ease.
Neatly integrated into the downtube, the battery powers lights, radar, and shifting, providing up to 24 hours in flashing mode or over 12 hours in steady mode.

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.
- KingPin™ With lightweight, bump-taming suspension built right into the frame, KingPin turns rough terrain into smooth sailing. It’s the extra boost you need to crush rugged paths, ride faster, and go further – no second thoughts needed!
