The Cervelo Caledonia Ultegra Di2 Carbon Wheel Exclusive Road Bike keeps us moving effortlessly through the wind with its aerodynamic profile without sacrificing long-distance comfort. The Cervelo All-Carbon construction offers lightweight durability and keeps us comfortable even as we reach sections of cobbles or rough back roads. The geometry is slightly more relaxed in the head tube angle but still features an aerodynamic design that helps us slice through the air. This Caledonia is spec'd with Shimano Ultegra Di2, delivering a smooth electronic shifting performance we can comfortably rely on. The lightweight battery of the Di2 system offers superior battery life, lasting from weeks to months, depending on our riding habits. To ensure we are always in the proper gear, we shift between the 50/34T chainring and 11-34T cassette with a simple touch of a button. Cervelo has us rolling on the carbon Shimano Ultegra wheels with Vittoria Corsa G2. 0 Tubeless Tires in this setup, delivering speed, control, and versatility to any ride.
