The Cervelo Caledonia-5 Contender Custom is engineered for riders who demand both performance and comfort across long distances and varied terrain. This thoughtfully curated build combines Cervelo&';s advanced carbon technology with race-inspired geometry and premium components, delivering a balanced platform that excels on steep climbs, fast descents, and rough road surfaces without sacrificing endurance-focused ride quality. We built this setup around the lightweight all-carbon construction of the Caledonia-5 frame to ensure efficient power transfer with exceptional stiffness while maintaining smooth characteristics that reduce fatigue over extended efforts. The tapered Caledonia-5 carbon fork enhances handling responsiveness and stability at speed, providing confident control even in challenging conditions. Cervelo SP24 carbon seatpost and HB13 carbon handlebars complete the integrated package with responsive handling and vibration-damping comfort. Versatility defines this build through generous 36mm tire clearance, allowing easy adaptation between smooth asphalt and gravel paths. Aero thru-axles (12x100/142) provide secure wheel mounting and precise handling characteristics, while the FSA IS2 headset contributes to stable, predictable steering across varied terrain. The Shimano Ultegra Di2 FD-R8150 2x12 wireless electronic drivetrain delivers smooth, instantaneous shifting with proven reliability across diverse road conditions. The Reynolds AR46 Disc carbon wheelset combines aerodynamic efficiency with endurance-focused stability, offering confident performance whether maintaining pace on flats or descending technical mountain passes. Perfect for cyclists seeking a complete endurance machine ready for ambitious adventures from century rides to mixed-surface exploration, this Contender Custom build eliminates the guesswork of component selection. Every element works cohesively to deliver cutting-edge performance with real-world versatility for riders who refuse to compromise between speed and comfort.
