Cannondale Synapse Carbon 4

Here's that description rephrased in my own way:

Hit the open road, whether you're aiming for a quick sprint or a long haul. This is top-tier performance built for everyday adventures.

Model Description:

Smart wireless tech meets rugged all-road capability. The Synapse Carbon 4 features Shimano 105 Di2, giving you that crisp, professional-level electronic shifting without the hefty price tag. The frame delivers the classic Synapse feel – effortlessly fast and incredibly stable – and can handle wider tires, mudguards, and those epic, all-day rides. It's the perfect balance of Sunday speed and everyday practicality.   

 


 

Ideal For:

Comfortable yet high-performance road cycling, tackling long distances, and fast group rides.

Key Features:

Lightweight, comfortably compliant, and aerodynamically sleek Synapse carbon frameset with integrated StashPort downtube storage.   

 

Shimano 105 Di2 electronic 2x12-speed drivetrain for impressively smooth gear changes.   

 

DT Swiss 470 wheels paired with Vittoria Rubino Pro IV 32c tires for excellent grip, durability, and speed.   

 

Cannondale C1 Aero 27 Carbon seatpost, blending speed with comfort.   

 

Fizik Vento Argo R5 saddle, designed for ergonomic comfort and pressure relief.
