Cannondale Synapse Carbon 4 For Sale Online

Wireless brains and all-road brawn. The Cannondale Synapse Carbon 4 uses Shimano 105 Di2 for a shifting experience that seems like it came straight from the pro tour, minus the bank loan. The frame provides the legendary Synapse ride—quietly quick, eternally composed—and pairs well with wide tires, fenders, and long days. Call it the perfect balance of Sunday speed and weekday practicality.

The 2025 Cannondale Synapse Carbon 4 redefines road performance with its long-range, fast-speed, and comfortable design. This bike can handle anything you ask of it because of its lightweight frame, wind-tunnel-sculpted tubing, and PB-blasting stiffness-to-weight.
