The Cannondale Synapse Si Ultegra Di2 is a performance endurance road bike built for long, fast days in the saddle while maintaining comfort and efficiency. Its lightweight carbon frame delivers smooth road compliance without sacrificing responsiveness, making it ideal for training, fondos, or endurance racing.


This build is equipped with a Shimano Ultegra Di2 2x11 electronic drivetrain, paired with 50/34 chainrings and an 11–34 cassette, offering precise shifting and a versatile gearing range for climbs and high-speed cruising.

Rolling on Fulcrum wheels fitted with Pirelli P7 32C tires, the bike balances speed with comfort and grip, and remains tubeless ready for further optimization. Finishing components include a Cannondale carbon seatpost, FSA 420mm bars, and a 100mm Giant stem. At approximately 16.9 lb, the bike remains impressively light for its category.
