The Cannondale Synapse Carbon 4 blends wireless shifting and all-road capability into a bike that feels fast, smooth and endlessly composed. Designed for riders who want weekend speed and weekday practicality, it offers a confident, quiet ride that adapts to long distances and changing terrain with ease.
Lightweight Carbon Frame with StashPort Storage: At the heart of the Synapse 4 is a lightweight carbon frameset engineered for comfort, compliance and aerodynamic efficiency. The integrated StashPort downtube storage keeps essentials tucked away discreetly, making the bike ideal for endurance rides, commutes and everything in between.
Shimano 105 Di2 for Effortless Electronic Shifting: Shimano’s 105 Di2 2x12-speed drivetrain brings pro-level shifting performance without the premium price tag. Each gear change is crisp, smooth and precise, allowing you to stay fully focused on the ride—whether climbing, sprinting, or rolling through long miles.
Confidence on Any Road Surface: DT Swiss 470 rims paired with Vittoria Rubino Pro IV 32c tires deliver a balance of grip, durability and rolling speed. Combined with the Cannondale C1 Aero 27 carbon seatpost, the bike maintains comfort over rough roads while keeping a fast, efficient feel under power.
It’s the perfect blend of modern tech, all-road versatility and smooth acceleration—built for riders who want one bike that simply does it all.
