Cervelo Caledonia 5 Ultegra Di2 Road Bike 2027 The 2027 Cervelo Caledonia 5 Shimano Ultegra Di2 endurance road bike is the definitive choice for cyclists who demand elite racing speed without sacrificing all-day riding comfort. Built around a beautifully sculpted carbon frame, this modern classic bridges the gap between traditional tarmac racers and long-distance endurance machines. It is engineered to swallow up road vibration, tackle rough asphalt, and excel in variable conditions while retaining the aggressive, aerodynamics-focused DNA that Cervelo is famous for. Complete with intelligent upgrades like the SB005 integrated in-frame storage system and premium Arundel Mandible carbon bottle cages, this bicycle is a versatile masterpiece that transforms any ambitious epic into a smooth, high-velocity journey. Precision Electronic Shifting and Professional Power Tracking At the core of this premium machine is the flawless Shimano Ultegra Di2 electronic drivetrain, offering lightning-fast, precise shifting across twelve speeds even under heavy pedalling loads. The versatile fifty-two thirty-six tooth crankset is paired with an eleven-to-thirty-four tooth cassette, giving you the perfect gear range to storm up alpine climbs and power down sweeping descents. To help you structure your training and pace your efforts perfectly, the drivetrain includes an integrated four-iiii Precision Pro dual-sided power meter. This race-proven setup is supported by Shimano hydraulic disc brakes and high-end centre-lock rotors, delivering consistent, confidence-inspiring braking power in dry sunshine or unexpected heavy rain. Enhanced Comfort and Premium Aero Wheel Dynamics This latest iteration elevates endurance performance with a wider tire profile and a completely optimized cockpit. The bike rolls on premium Reserve carbon wheels laced with DT Swiss internal components that offer elite two-forty level performance, wrapped in plush, fast-rolling thirty-two-millimetre Vittoria Corsa N.EXT tubeless tyres for unmatched grip and compliance. Up front, the lightweight steerer compression plug and carbon handlebar system offer clean internal cable routing with full handlebar swap eligibility to tailor your precise fit. Finished with a Prologo Nago R4 Tirox lightweight saddle and a carbon seatpost, this incredibly compliant build ensures you stay fresh and powerful through your longest, most demanding days in the saddle.
