The Cannondale Synapse Alloy features endurance geometry that provides stable, confident handling and a more upright riding position for all-day adventures.  This is the ideal first road bike for those looking for exceptional handling, comfort, performance, versatility and value.  

Cannondale Synapse bike fork and frame

Size-Optimized Design

To ensure that riders of all sizes get the same handling and ride feel, the Synapse uses three different steerer diameters and fork rakes across the size range.

Cannondale Synapse flat mount disc brake

Flat Mount Disc Brakes

Light, clean and easy to adjust flat mount discs on all models, with 142x12mm rear and 100x12mm front thru-axles.

Cannondale Synapse Power pyramid seat tube

Power Pyramid

The seat tube splits asymmetrically to meet the wide, 73mm BB30A for maximum stiffness with minimal weight. (Hi-MOD models only. Non Hi-MOD versions feature the same dimensions, without the split.)

Cannondale Synapse bike frame

SAVE Micro-Suspension

A system of engineered flex zones in the rear stays, seat tube, seatpost and fork allows just the right amount of controlled flex to keep you comfy, while maintaining lateral stiffness for max efficiency and control.

Clean Cable Management

Interchangeable plate on the top of the downtube
allows tidy routing for mechnical systems and
complete integration of Di2 and eTap systems.

Cannondale Synapse frame

Asymmetric Frame Design

Distinct asymmetry in the fork and rear triangle
enhances stiffness and improves braking performance.
