Cannondale Synapse Carbon 2 SmartSense SMU: Comfort and Performance for Endurance Cycling

The Cannondale Synapse Carbon 2 SmartSense SMU is a carbon endurance road bike designed to deliver speed, comfort and versatility over long distances. Ideal for Gran Fondos, group rides and road adventures, it combines an aerodynamic frame with high-end components and integrated visibility technologies.

Synapse Carbon Frame with Proportional Response Technology

The Synapse Carbon frame features Proportional Response construction, which optimizes frame geometry and carbon structure for each size.

The frame is designed to combine low weight, stiffness and comfort, helping reduce fatigue during extended rides.

Internal cable routing and the Delta steerer keep the front end clean and streamlined, improving aerodynamic integration.

SmartSense Gen 2.0: Integrated Lights and Radar

The Cannondale Synapse Carbon 2 SmartSense SMU features the SmartSense Gen 2.0 system, developed to improve rider visibility and awareness of surrounding traffic.

The system includes an 800-lumen LightSkin U1E front light and a Garmin Varia eRTL615 rear radar with an integrated light, which detects approaching vehicles.

A removable 43.2 Wh internal battery powers the SmartSense system and SRAM AXS shifting, providing a single integrated power solution.

SRAM Force AXS Wireless Electronic Drivetrain

The SRAM Force AXS 2x12 drivetrain delivers wireless electronic shifting and a versatile range of gears suitable for different routes.

The 46/33 crankset and 10-36 12-speed cassette provide a wide selection of gears for climbs, flat roads and long-distance rides.

The SRAM Force AXS hydraulic disc braking system, with 160 mm rotors, completes the setup.

Reserve 42|49 Turbulent Aero Carbon Wheels

The Reserve 42|49 Turbulent Aero carbon wheels are designed to deliver aerodynamic performance and versatility over long distances.

They are paired with DT Swiss 370 hubs and Vittoria Rubino Pro IV 700x32c tires, creating a setup focused on rolling efficiency and road comfort.

StashPort: Integrated Storage for Accessories

The StashPort system, integrated into the down tube, allows riders to carry small accessories and essential tools directly inside the frame.

The included StashBag helps organize the storage compartment, keeping accessories protected and easily accessible.

Comfort and Versatility for Long Distances

The Cannondale Synapse Carbon offers tire clearance for up to 48 mm at the front and 42 mm at the rear, with at least 4 mm of additional clearance on each side.

The aerodynamic D-shaped seatpost contributes to vertical compliance, while the Fizik Vento Argo R5 saddle completes a setup designed for long hours in the saddle.

The Cannondale Synapse Carbon 2 SmartSense SMU is a complete solution for cyclists looking for a carbon endurance road bike with SRAM Force AXS electronic shifting, Reserve wheels and integrated SmartSense technologies.
