Cannondale Synapse Carbon 3 SmartSense 2025 - Road Bike



Lightweight
Built to go fast, designed for big days out, and made to keep you comfortable, the Synapse pushes the limits of what an endurance road bike can do. With a sub-1000g carbon frame, wind-cheating tube shapes and impressive stiffness-to-weight, it’s ready for wherever the ride takes you.
Comfortable
Thanks to updates in carbon layup construction, the new Synapse is now 18% more compliant than the previous model. This added comfort makes a noticeable difference on rougher roads, helping riders stay fresher and more in control, mile after mile. Additional features such as the D-shaped design of Synapse’s seatpost and 42mm tyre clearance boosts vertical compliance and improves aerodynamics, reducing muscle fatigue so that you stay fresher on those longer days.
StashPort
The all-new StashPort downtube storage system offers on-the-go practicality without compromising clean lines. Paired with the StashBag, it keeps ride essentials secure and out of sight. Hidden top tube bag mounts, discreet mudguard fittings, and clearance for high-volume tyres make the new Synapse ready for big miles and demanding conditions alike.
SmartSense
The 2nd generation of the SmartSense system with intelligent lights and radar is better than ever. The headlight is smaller, yet much brighter offering up to 800 lumens, the radar and taillight are neatly integrated under the seat, and the battery is now hidden neatly in the downtube. This battery now has more than double the capacity of the previous version with up to 24 hours of run time for those long days in the saddle.
