Cannondale Synapse Carbon 2 2025

The road reinvented

Pedal fast, comfortably, confidently. Wherever the road takes you, ride it with Synapse; our most versatile, comfortable, multi-purpose road bike for every adventure. Excellent in open spaces, uphill and downhill, on rough asphalt. Designed to give comfort, handling and long rides

Extremely smooth
On the Synapse, comfort is standard. Specific flex zones on the rear frame, seat tube and seatpost absorb bumps and bumps in the road, without adding unnecessary weight or isolating you from riding pleasure.

So fast
Lightweight carbon construction. Imperceptible aerodynamic shape of frame and fork. Size-specific design to provide appropriate stiffness. It all comes together to create a bike that is ready to take flight.

So multi-purpose
With a balanced riding position, confidence-inspiring handling, room for 35mm clinchers for added comfort and grip, and plenty of bottle cages/equipment carriers, you can tackle any trail with the Synapse, anywhere you want.
