The Synapse Carbon 2 SmartSense is Cannondale's endurance road bike for long day rides and fast group outings. The integrated SmartSense Gen 2 light and radar system ensures that you are seen and warned in time when vehicles approach from behind. The carbon frame with Proportional Response construction is individually tuned in geometry, carbon layup, and stiffness depending on size. The Delta steerer of the full carbon fork allows for internal cable routing with a sleeker head tube profile, and tire clearance goes up to 48 mm in the front and 42 mm in the rear. Shifting is wireless with the SRAM Force AXS 2x group, and braking is done with SRAM Force hydraulic disc brakes. The Reserve 42|49 Aero carbon wheels noticeably reduce aerodynamic drag and maintain speed on rolling terrain better than conventional rims. A StashPort for tools and spare materials is located in the down tube. The SmartSense Gen 2 system is fully integrated into the frame and seat post: a front light with up to 800 lumens, a combined Garmin radar tail light that detects following traffic and warns the rider, as well as a shared battery in the down tube with over 24 hours of runtime. No external mounts, no separate charging cables, no visible wiring. For anyone looking for a technically advanced endurance road bike that is fast, comfortable, and safe at all times.
