Road Reimagined
Go long, go short, go fast. This is WorldTour performance for real world rides.

Smooth. Precise. And built to stay that way. Synapse Carbon 2 Di2 pairs an endurance-optimised carbon frame with Shimano’s peerless Ultegra Di2 shifting and the race-bred DT Swiss ERC 45 wheelset. Designed for the rider who appreciates the feel of a fast bike built to go the distance—and the silence of a drivetrain that’s always in the right gear. Add in massive tire clearance and sleek integration, and it’s clear: this thing’s more than ready.

What it's for
Comfortable high-performance road riding, long distance missions, fast group rides

Highlights

  • Lightweight, smoothly compliant, sleekly aero Synapse carbon frameset with StashPort downtube storage

  • Ultegra Di2 – Effortlessly accurate shifting from Shimano's penultimate electronic 12-speed drivetrain

  • DT Swiss carbon road wheels - lightweight all-road capability

  • Cannondale C1 Aero 27 Carbon seatpost - speed meets comfort

  • Fizik Vento Argo R5 saddle - ergonomic comfort with pressure relieving cutout



Features

  • Real World Performance: Designed to go fast, built to go long, and made to keep you comfortable, the Synapse redefines road performance. With a lightweight frame featuring wind-tunnel-sculpted tubing and PB-blasting stiffness-to-weight, it’s a bike that’s ready for anything you demand of it. Just ask Lachlan Morton why he trusted it for his record-smashing lap of Australia. Unreal speed, engineered for real-world roads.​

  • Compliant Comfort: With advancements in our carbon layup, our engineers have made the new Synapse 20% more compliant than its already butter-smooth predecessor, ensuring you feel 100% more comfortable even on the roughest roads.

  • Like A Glove: A great fit and feel makes for a great ride. And with our Proportional Response Construction, every rider gets that as standard. From the carbon layup through to the geometry, everything on Synapse has been tuned and tested by frame size. So that your bike works in harmony with you to give the best possible ride for you and your height.

  • Bring it all, bring it on: Cannondale's all-new StashPort storage system in the downtube is there when you need it and hidden when you don’t. Paired with its StashBag buddy, you can bring along your ride essentials and know that they’ll be secure, whatever you get up to out there. Meanwhile, best-in-class tire clearance lets you take the idea of riding for longer to a whole new level.

  • Big Ride Rubber: Best-in-class clearance for tyres with a maximum measured width of up to 48mm in the front and 42mm in the rear - with at least 4mm of extra clearance on each side - makes Synapse a true, ride-longer, ride-whatever kind of road bike.

  • StashPort + StashBag: StashPort is Cannondale's take on a downtube storage system, accessed beneath the water bottle cage. While every Synapse includes StashBag, a specially designed bag for tools and other ride essentials.

  • D-Lightful: The D-shaped design of Synapse’s seatpost enhances aerodynamics and boosts vertical compliance. Reducing muscle fatigue so that you stay fresher on those longer days.

  • Fly Delta: The unique-to-Cannondale v-shape Delta Steerer keeps your cockpit tidy and cables routed internally. While the reduced headtube frontal area brings aero gains to the party. As well as sleeker good looks.
