CANNONDALE SYNAPSE SMARTSENSE LAB71 BIKE

Long rides, short rides, fast rides. We bring WorldTour performance into the real world.
Here we stand at the top of the pyramid, where race-bike ambition meets luxurious real-world rideability. The Synapse LAB71 is built with our ultra-light Hi-MOD carbon, engineered for rides that last longer than your playlists. The SRAM RED AXS XPLR drivetrain offers gear choices for every situation, plus a power meter. The premium Reserve 42|49 wheels roll like silk, the SmartSense Gen 2 system keeps you visible, and our StashPort system carries everything you need when the day stretches long. Fast. Refined. Ready to disappear beneath you—while still standing out.

Real-world performance

Designed to be fast and comfortable over long distances, the Synapse redefines road performance. With a wind-tunnel-shaped Hi-MOD frame weighing under 1000 grams and an incredible stiffness-to-weight ratio, this bike is ready for anything. Tested by Lachlan Morton during his record-setting ride across Australia: incredible speed, engineered for real-world roads.

Ride safely

More visibility, more awareness, more integration with our second-generation SmartSense system. Powered by a single hidden battery. The intelligent lights adapt to make you more visible to other road users, while the rear-facing Garmin radar keeps you informed of approaching traffic—letting you ride confidently, any time of day or night.

Lights

The front light is small but powerful, turning night into day with its 800 lumens. The daytime-running-light mode keeps you safe, while the stem-mounted design keeps the cockpit clean.

Radar

The rear radar watches your back, alerting you to approaching vehicles so you can ride with peace of mind.

Battery

Perfectly integrated into the downtube, the battery powers lights, radar, and drivetrain, delivering up to 24 hours of runtime in flashing mode or more than 12 hours in steady mode.

Comfort

Thanks to improvements in carbon lay-up, our engineers have made the new Synapse 18% more compliant than the already impressive previous model—ensuring maximum comfort even on rough roads.

Tailored ergonomics

It fits you perfectly and makes every ride unforgettable. Thanks to our Proportional Response design, this comes standard for every rider. From carbon lay-up to geometry, every element of the Synapse is tuned and tested for each frame size. The bike works in perfect harmony with you, delivering the best possible experience based on your height.

Ready for anything

Our new StashPort storage system integrated into the downtube is always at hand when needed and discreetly hidden when not. Paired with the StashBag pouch, you can carry all your essentials securely, no matter where you ride. Meanwhile, class-leading tire clearance lets you take the idea of riding further to a whole new level.
