Cannondale Synapse Carbon 1 RLE Disc Road Bike 2023

With its uncompromising specification and state of the art technology, the Cannondale Synapse Carbon 1 RLE Disc Road Bike reigns supreme on smooth tarmac, pitted roads and everything in between. All-new for this model year, this latest edition of the Synapse is an evolution of an already proven formula. It couples sublime vibration damping with reactive handling, delivering an addictive ride quality that sees the miles melt away. No distance is unachievable, and each frame size receives a unique carbon layup to provide tailored performance. 

At the heart of the new Synapse is the game-changing SmartSense system. Sleekly integrated into the bike are a Foresite front light, Hindsite rear light and a radar system that alerts the user to vehicles up to 140 metres away. Designed to be an extra set of eyes and ears, the SmartSense system keeps you focused, powered by a single quick-release battery, merged neatly into the downtube. 

The Dura-Ace Di2 drivetrain is at the pinnacle of shifting, offering minimal weight and maximum performance. A HollowGram KNØT wheelset utilises DT Swiss 240 internals to ensure rapid acceleration off the line, while the ultralight carbon construction reduces rolling weight for a lively ride character. 30c Vittoria tyres deliver plush comfort and traction, and the frame itself has enough room for up to 35c rubber. Hydraulic disc brakes instil confidence on steep descents, offering powerful performance even in wet weather conditions. 


  • Subtle aerodynamic frame changes deliver free speed without any additional weight
  • Wide tyre clearance for up to 35mm road tyres
  • An all-new frame design sees enhanced compliance to boost ride comfort
  • The SmartSense battery and integrated lights work to improve your visibility and awareness on the road
  • Foresite front light offers 350 lumens of brightness and is made in conjunction with Leyzne
  • Hindsite light and radar system are born from a collaboration with Garmin
  • The rear radar system can sense vehicles up to 140m away and features a “Brake Alert” function to highlight your braking to other road users
  • Threaded BSA bottom bracket and tube-in-tube internal routing offer simple home maintenance
  • Hidden rack/mudguard mounts improve versatility
  • Adaptable design with a dynamic and responsive ride character
  • Proportional Response Construction frame design ensures the same ride quality across the entire size range
  • The Shimano Dura-Ace Di2 electronic groupset delivers the ultimate in shifting performance
  • Hydraulic Shimano disc brakes provide confidence in wet-weather conditions
