Cannondale Synapse Carbon 5 2025

The road bike, rethought

Long rides, short rides, fast rides. We bring WorldTour performance to the real world. Quality assembly. Ready to go. Synapse Carbon 5 translates Cannondale's philosophy of high comfort and high capability into solid specs: Shimano 105 mechanical gearing, carbon frame, and wide wheel passage for real-world roads. Whether it's your first real bike or your 15th, she seems to know the secret: the right bike makes all the difference.

Performance for the real world
Designed to be fast and comfortable over long distances, the Synapse redefines performance on the road. With a lightweight wind-tunnel-molded frame and an incredible stiffness-to-weight ratio, it's a bike ready for anything. Just ask Lachlan Morton, who broke his own lap record for Australia on this bike. Dream speeds designed for the real world.

Comfort
Thanks to improvements in carbon layering, our engineers have managed to make the new Synapse 18% more flexible than the already incredible previous model, ensuring maximum comfort even on the bumpiest roads.

Tailored Ergonomics
It fits you perfectly and makes your rides unforgettable. And thanks to our Proportional Response construction, this is standard for every cyclist. From the layering of the carbon to the geometry, every element on the Synapse has been fine-tuned and tested for each frame size. That way the bike works in perfect harmony with you, ensuring the best possible experience based on your height.

Ready for anything
Our new StashPort storage system found in the down tube is always at hand when you need it and discreetly concealed when you don't. Paired with the StashBag, you can carry all your essentials with you on rides, knowing it will be safe no matter what you do. Meanwhile, the best-in-class wheel transition lets you take the idea of riding longer to a whole new level.

Tires for Big Adventures
With generous tire clearance of up to 48 mm at the front and 42 mm at the rear with at least 4 mm of extra clearance per side, the Synapse is a road bike to suit all needs, to ride longer and on any route.

StashPort + StashBag
StashPort is our idea of a storage system on the down tube, accessible under the bottle cage. Each Synapse comes with StashBag, a specially designed pouch for tools and other essentials for your rides.

D-shaped seatpost
The Synapse's D-shaped seatpost design improves aerodynamics and vertical comfort while reducing fatigue, to keep performance high even on the longest rides.

Aerodynamics that make you fly
Cannondale's exclusive V-shaped Delta steerer tube keeps the handlebar area clean thanks to internal cable routing, while the head tube's reduced frontal area provides aerodynamic benefits. Functional and elegant.

Wheel sensor
Cannondale's wheel sensor provides highly accurate speed, distance and route information, maintenance reminders and more via the Cannondale app
