The Cervelo Caledonia-5 is built for riders who chase ultra-distance adventures, endurance events, and high-speed all-day efforts without compromising race-bike performance. Created around the philosophy of tackling "Big, Stupid Rides," the Caledonia-5 blends the speed and responsiveness of a modern race bike with the comfort, versatility, and practicality required for long-distance riding. Whether you&';re lining up for an endurance race, linking together remote roads, or venturing onto rough pavement and light gravel, the Caledonia-5 is engineered to keep you moving efficiently hour after hour. The all-carbon frame features dropped seat stays that increase vertical compliance and reduce rider fatigue on rough surfaces, while a stiffer downtube preserves the sharp handling and power transfer expected from a Cervelo. Integrated in-frame storage adds practical self-sufficiency, providing secure space for ride essentials without disrupting the bike&';s clean aerodynamic profile. Tire clearance for up to 36mm tires and integrated fender mounts expand the bike&';s capability across changing road conditions and mixed-surface routes. Fully internal cable routing and refined aerodynamic shaping contribute to increased efficiency, while the updated split bearing cap system simplifies fit adjustments and maintenance. SRAM Rival AXS E1 wireless electronic shifting delivers dependable precision in all conditions, paired with Reserve 42|49TA carbon wheels featuring Turbulent Aero technology for aerodynamic performance and stability across varied terrain.
