2025 Cannondale Synapse Carbon 4 Road Bike
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. Call it the sweet spot between Sunday speed and weekday practicality.
