Cannondale’s StashPort storage system, neatly integrated into the downtube, gives you a practical place to store ride essentials, tools or spares without cluttering the frame or compromising aerodynamics. Fully SmartSense Gen 2 equipped, the bike also includes integrated lights and radar functionality for extra safety and visibility on open roads.

At the front, the Hi-MOD carbon fork with a Delta steerer delivers exceptional stiffness and direct handling, especially noticeable when descending at speed or changing direction under load. Internal cable routing keeps the whole setup sleek and streamlined.

Where the Synapse Carbon 1 really shines is in its drivetrain. The Shimano Ultegra Di2 12-speed groupset delivers fast, wireless shifting with incredible precision and consistency. Whether you're on a club ride, tackling an epic sportive or just climbing out of the saddle, every gear change is seamless. A 4iiii PRECISION 3+ PRO power meter is fitted as standard to the Ultegra chainset, giving you the data you need to train smart and pace perfectly.

Braking is handled by Shimano Ultegra R8170 hydraulic disc brakes, matched with 160mm rotors front and rear for superb stopping control in all weather. These brakes are race-proven, reliable and highly modulated.

The Reserve 42|49 carbon wheelset features a mixed-depth design for aero performance and crosswind stability, built on DT Swiss 350 hubs and laced with Sapim CX-Ray aero spokes for speed and strength. Fitted with Vittoria Corsa PRO Control 32c tyres, the wheels offer superb grip and handling especially useful on unpredictable UK roads or early season races.

The finishing kit keeps performance front and centre. The SystemBar R-One integrated cockpit, co-developed with MomoDesign, improves aero flow while enhancing comfort and responsiveness. A Cannondale C1 Aero carbon seatpost and Fizik Vento Argo R5 saddle ensure all-day support without compromising speed.

For riders who want endurance comfort with pro-level performance and smart integration, the Synapse Carbon 1 is a fast, future-ready road bike built to go long and go fast.

Occasionally, without notice, manufacturers change product design and/or specifications.
