Product Highlights

Cannondale's extensive aluminium expertise makes the frame light, responsive and durable.

Offering powerful and consistent stopping power these brakes are also easy to maintain.

Low enough for speed but upright enough for comfort over the longest rides.

Manipulated frame and fork tube shapes afford increased compliance and comfort over rough roads.
Cannondale Synapse Aluminium Sora Disc Road Bike 2021
The Cannondale Synapse Aluminium Sora Disc Road Bike is stiff, light and versatile - perfect for commuting, challenging sportives or the weekly club run. The endurance geometry is just upright enough to feel comfortable but is still low enough to promote speed and efficiency. A full carbon fork takes the edge off road buzz, reducing the onset of fatigue so that you can comfortably tackle long rides.
Cables are routed internally so that they are clear from water and dirt, keeping maintenance low, and the Shimano Sora groupset is durable enough to withstand the rigours of frequent riding. Cable actuated disc brakes are easy to maintain or adjust and will inspire confidence in poor weather or when riding technical roads and the frame will accommodate up to a 32mm tyre that will further enhance comfort and handling.
