Cannondale Synapse Carbon 3 Smart Sense bike

Road Reimagined

Go long, go short, go fast. This is WorldTour performance for real world rides. The all-rounder that’s anything but average. With SRAM’s crisp-shifting wireless electronic Rival AXS 2x, SmartSense Gen 2 visibility and awareness tech, and the Synapse’s legendary ride quality, this one’s engineered to disappear beneath you—until you need it most. Whether the sun’s setting or the pace is rising, it keeps you alert, lit, and in command. Call it modern endurance with eyes in the back of its head and plenty of watts in reserve.

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.​

Ride Confident
More visibility, more awareness, more integration, with next-gen SmartSense system. All running from a single concealed battery. Intelligent lights adapt to let other road users know you’re there. While the rear-facing Garmin radar keeps you switched on to approaching traffic. Letting you ride the bike that’s up for anything, whatever time of day or night.

Lights
The headlight is small yet powerful, turning night into day with up to 800 lumens. A daylight function keeps you safe, while its stem-mounted design keeps the cockpit clean.

Radar
The rear radar watches your back, alerting you to approaching vehicles so you can ride with ease.

Battery
Neatly integrated into the downtube, the battery powers lights, radar, and shifting, providing up to 24 hours in flashing mode or over 12 hours in steady mode.

Compliant Comfort
With advancements in carbon layup, 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 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
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.

Smarter SmartSense
Gen 2 of intelligent lights and radar system is smaller, brighter, longer lasting, and better integrated than ever. One battery – now hidden neatly in the downtube - powers the lights, rear-facing radar, and the SRAM AXS shifting.

Big Ride Rubber
Best-in-class clearance for tires 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 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. It also houses the SmartSense battery, which provides glovebox-style lighting when StashPort cover is opened.

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.

Wheel Sensor
Cannondale Wheel Sensor delivers hyper-accurate speed, distance and route info, service reminders, and more via the Cannondale App
