Cannondale Synapse Lab71 frame 2025
Road Reimagined
Go long, go short, go fast. This is WorldTour performance for real world rides.
Real World Performance
Designed to go fast, built to go long, and made to keep you comfortable, the LAB71 Synapse takes all-around road performance to the next level. With a sub-1000-gram Hi-MOD frame, featuring wind tunnel-sculpted aero tubing, exceptional stiffness-to-weight, and a silky ride, it’s a bike that’s ready for anything you demand of it. Proven by Lachlan Morton on his record-smashing lap of Australia, Unreal speed, engineered for real-world roads.
Ride Confident
More visibility, more awareness, more integration, with our 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.
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
Our 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 our 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 our 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.
SystemBar
Sleek and light, the SystemBar R-One carbon cockpit is the perfect ride command center, giving you an aero advantage, clean integration, and all-day comfort.
Wheel Sensor
Cannondale Wheel Sensor delivers hyper-accurate speed, distance and route info, service reminders, and more via the Cannondale App
