The Cannondale Synapse Carbon 4 redefines endurance road riding with a perfect blend of pro-level performance and real-world practicality. Built around a lightweight, aero-optimized carbon frameset, it delivers a buttery-smooth ride that’s now 20% more compliant for comfort on rough roads. Shimano 105 Di2 electronic shifting ensures flawless, fast gear changes, while DT Swiss 470 wheels paired with Vittoria Rubino Pro IV 32c tires provide speed, grip, and durability across long miles. Thoughtful details like the integrated StashPort downtube storage, aerodynamic C1 Aero 27 carbon seatpost, and Fizik Vento Argo R5 saddle round out a package designed for fast group rides, long-distance missions, and everyday versatility. Confident, comfortable, and capable—the Synapse Carbon 4 is endurance performance reimagined.
