The Cerve;lo Caledonia-5 is built for Big, Stupid Rides, the ultra-distance, ultra-fast efforts that define the outer limits of endurance cycling. Since its introduction, athletes around the world have been exploring just how big and how stupid those rides can be, and the Caledonia-5 is engineered to handle it all. This is a race bike designed for long-distance, high-speed racing where fit and handling are geared toward comfort without sacrificing the legendary Cerve;lo race bike feeling that demands performance when it counts. Every refinement on the new Caledonia-5 addresses what matters to riders pushing their bodies and equipment to the absolute limit. The most significant addition is integrated in-frame storage, designed discreetly for a small multi-tool, spare tube, and CO2 canister. Out of sight, out of mind until you need it most. The dropped seatstays, inspired by Cerve;lo&';s gravel platform, make the rear triangle more acute and vertically flexible, absorbing chatter on imperfect tarmac while a bit more downtube stiffness maintains the pro-level responsiveness Caledonia is known for. This balance ensures you stay fresh over the brutal hours of ultra-distance racing. Completely internal cable routing and carefully optimized aero tube shapes provide the free speed every Cerve;lo delivers, helping you battle the wind when running on fumes. Split bearing caps allow fit adjustments without bleeding the brakes, simplifying setup for the inevitable fine-tuning long rides demand. With 36mm tire clearance and fender mounts, you&';re equipped for any surface and any weather. SRAM Rival AXS E1 electronic drivetrain with integrated power meter delivers precise, wireless shifting across changing terrain and pace, while Reserve 42|49TA carbon wheels, proven across Paris-Roubaix and Grand Tours alike, provide all-day capability with aerodynamic sensibilities.
