CANNONDALE Synapse Carbon 4

Cannondale Synapse Carbon 105 Di2 – Endurance Carbon Road Bike

Road Reimagined
Go long, go short, go fast. WorldTour-level performance built for real-world riding.

Model Description
The Cannondale Synapse Carbon 105 Di2 blends speed, comfort, and modern tech into a true endurance carbon road bike built for real-world performance. Powered by the Shimano 105 Di2 12-speed electronic drivetrain, it delivers fast, precise, and effortless wireless shifting inspired by the pro peloton—without the pro-level price tag.

The Synapse carbon frame delivers its signature ride feel: smooth, stable, and quietly fast. With clearance for wider tires and compatibility with fenders, it’s ready for long-distance rides, rougher roads, and everyday use.

This is the perfect balance between Sunday speed and weekday practicality.

What it’s for
• Endurance road riding with comfort and performance
• Long-distance rides and all-day missions
• Fast group rides and training
