Cannondale Synapse Carbon 4 Disc Road Bike 2023

A fresh take on a proven formula, the all-new Cannondale Synapse Carbon 4 Disc Road Bike delivers comfort and speed on longer, endurance style rides. The frame is lightweight and responsive, with its geometry and carbon construction being identical to that of the top-tier Synapse models. A Proportional Response size-specific carbon layup ensures the same ride quality for all riders, keeping rigidity and compliance consistent across the size range for a bespoke feel. A threaded BSA bottom bracket allows for simple home servicing, while tube-in-tube internal routing makes threading cables a breeze.

The all-new frame design steps above and beyond the previous editions, delivering supreme comfort with an aerodynamic twist. Compliance has been improved to damp vibration, reducing fatigue on longer rides, while truncated tube profiles minimise wind resistance to enhance efficiency. 

The parts specification blends value with performance, with the 10-speed Shimano Tiagra offering crisp shifting and a wide gear range. Shimano Tiagra hydraulic disc brakes provide ultimate control whilst descending, even in wet weather, and hidden mudguard mounts allow you to ride all year round. The Cannondale wheelset features reliable thru-axle Formula hubs, and the in-house Cannondale cockpit is lightweight and ergonomic. 


  • Subtle aerodynamic frame changes deliver free speed, without any additional weight
  • Wide tyre clearance for up to 35mm road tyres
  • An all-new frame design sees enhanced compliance to boost ride comfort
  • SmartSense compatible design
  • Threaded BSA bottom bracket and tube-in-tube internal routing offer simple home maintenance
  • Hidden rack/mudguard mounts improve versatility
  • Adaptable design with a dynamic and responsive ride character
  • Proportional Response Construction frame design ensures the same ride quality across the entire size range
  • Reliable Shimano Tiagra groupset delivers crisp, 10-speed shifting
  • Hydraulic Shimano disc brakes provide confidence in wet-weather conditions
