Synapse Carbon 4

An endurance road bike ready for anything. The Synapse Carbon 4 perfectly balances lightweight, aerodynamics and all day comfort. Wireless brains meet all-road brawn. Synapse Carbon 4 runs Shimano 105 Di2 for a shifting experience that feels straight off the pro tour, minus the bank loan. The frame delivers that signature Synapse ride—quietly fast, endlessly composed—and plays nice with wide tires, fenders, and long days.
