Cervelo 2025 CALEDONIA-5 Rival Axs

FOR YOUR BIG, STUPID RIDES. On the fringes of cycling and triathlon, already endurance-oriented sports, there are athletes pushing their bodies and equipment to the limit. Ultra-distance, but ultra-fast. We call these Big, Stupid Rides, and since the introduction of the Caledonia in 2020, athletes around the world have been exploring just how big and just how stupid those rides can be. These athletes reach for the Caledonia-5. It's built to handle long-distance, high-speed racing-with fit and handling geared toward comfort, but without sacrificing the Cervelo race bike feeling.
