Cannondale Synapse Carbon 4 2023 Rose Road Bike

Available with Cannondale in the sizes shown above. Expect delivery within 3-4 working days of placing an order.

With Synapse, comfort is built in. Discreet flex zones in the rear triangle, seat tube and seatpost absorb road chatter and bumps without adding weight or isolating you from the ride experience.

Lightweight carbon construction. Subtle aerodynamic shaping of the frame and fork. Size-specific design for perfectly tuned stiffness. It all adds up to a machine that loves to fly.

With a comfortably balanced riding position, confidence-inspiring handling, room for 35mm wide tires for cushion and grip, and plenty of gear/bottle mounts, Synapse is ready to rock on any road, anywhere.

Lightweight Synapse Carbon Frameset / Full SmartSense system with radar and lights
