Cervelo's Caledonia 5 Ultegra Di2 Road Bike is our top choice for riders seeking a versatile do-it-all bike for long-distance adventures on smooth roads, bumpy backroads, and whatever other terrain we may encounter. The carbon construction is durable, lightweight, and stiff, providing exceptional power transfer, and the tapered fork absorbs shocks for a smooth, fatigue-free ride, no matter how bumpy. Designed to take us on our next century ride, the Caledonia 5 features an aerodynamic design that minimizes drag and keeps us looking fast, while the carefully engineered geometry keeps us in a comfortable and efficient riding position for optimal performance. The Shimano Ultegra Di2 12-speed drivetrain provides crisp, intuitive shifting and trustworthy braking on this model of the Caledonia 5. The 52/36t chainrings and 11-34t cassette range combination offer a wide variety of gear ratios to ensure we are always in the gear necessary to climb up a 10% grade and sprint down the other side. Plus, shifting between gears is so easy with a simple tap on the ergonomic dual-control levers. To keep us rolling as fast and comfortable as possible, Cervelo built this bike with the Reserve 42|49 TA carbon wheelset, prioritizing stiffness, strength, and weight savings to take us to the top of the mountain and the podium.
