20 years ago, the original Synapse did something pretty special – it quietly reimagined the whole road riding experience. Reasoning that most riders were really looking for something other than the high-strung, second-shaving pro race bikes, or the mild and mellow “comfort” road bikes available at the time, Synapse blazed a new path. By melding race-level performance and weight with real rider-friendly comfort and handling, Synapse set the template and the tone for what would become known as the Endurance road bike category. Fast forward two decades and six generations of Synapse, and it’s still out front, setting the pace and helping define what the future of core, for-the-love-of-the-ride, road bikes will look like. Synapse is real performance, for the real world. 

Unreal performance for real world roads. Unless you’re a WorldTour pro, the Synapse is the perfect road bike for any job. Whether you’re tackling a record-breaking lap of Australia like Lachlan or smashing the not-so-social Sunday ride with your mates, the Synapse exceeds expectations. It blends WorldTour-level aerodynamics and stiffness-to weight with top-tier tire clearance, compliance, and smart features. 

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 sub-1000-gram lightweight carbon 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 deliver the best possible ride.
  • Bring it All, Bring it On: Our all-new StashPort downtube storage system is there when you need it and out of sight when you don’t. Designed to work seamlessly with its StashBag companion, it keeps your ride essentials secure no matter where the road takes you. Plus, with hidden top tube bag mounts, discreet fender mounts, and room for high-volume, capable tires, the new Synapse is built to go long and go hard, no matter what the day brings.
  • Ride Confident: Enjoy improved visibility, enhanced situational awareness, and unmatched convenience with the second generation of our SmartSense system. More discreet, more integrated, and more powerful than ever, this intelligent and connected system of lights, radar, sensors, and our Cannondale app brings easy peace of mind to every ride. All running from a single concealed battery, the rear-facing Garmin radar keeps you switched on to approaching traffic, while intelligent headlights and taillights adapt blink patterns and/or brightness to let other road users know you’re there. It will even power your SRAM AXS shifting. And with just one long-lasting battery to charge, it’s
    easier than ever to get out and ride with confidence.
