Summary
The Cannondale Synapse is celebrated for its blend of performance and comfort, making it a standout in the endurance category. Its design focuses on real-world performance, with features like size-specific geometry, lightweight frames, and enhanced compliance for a smoother ride. The bike also boasts innovative technology such as the SmartSense system for integrated lighting and radar, and ample storage options with StashPort. While it excels in versatility and comfort, some reviews note limitations with tire clearance and the SmartSense system's compatibility with certain components.

The Cannondale Synapse is what happens when you take performance seriously—but not so seriously that you forget to smile during a five-hour ride.
Bikerumor"The Synapse now has drag figures that are basically on par with the previous third-generation SuperSix Evo, which, from all of our testing, would be an extremely competitive bike if it was still in the pro peloton," says Nathan Barry, Cannondale’s senior design engineer.
Canadian Cycling MagazineThe Synapse goes further than the other two bikes to prepare you for longer rides.

Radar comes standard
Comfortable all-day ride
Stable and confidence-inspiring handling
SmartSense radar and light integration
Simplicity of design (standard seatpost clamp, threaded BB)
Understated graphics
Shimano Ultegra Di2 12-speed with compact gearing
Fender mounts
Tubeless-ready wheels
SmartSense radar triggers false warnings from cars in other lanes or parallel roads
SmartSense battery charging finicky, needs removal and reset
Battery capacity requires charging after every ride
Heavy wheels (1740g) affect acceleration and climbing
No carbon seatpost for added compliance at this price

The new Synapse is a real joy to ride – but in this guise it lacks value against its competitors

Not great value for money
