The Rca is the world’s lightest frameset, showcasing the best of our knowledge, testing, and advanced Project California engineering.
Whether you’re attacking epic climbs or speeding over cobblestones, the R5 Disc will help you survive, thrive and dominate. This ultra-lightweight race machine sets new benchmarks for performance, usability and confidence-boosting control thanks to integrated disc-brake technology, a new pro fit, unrivalled stiffness, stable and responsive handling, and myriad aero enhancements.
The stiffest road frame we have ever produced joins forces with performance-enhancing comfort, confidence-inspiring handling, world-class aerodynamics, ultra-lightweight design and the latest disc-brake technology.
After years of research and testing on the road, in the lab and in the wind tunnel, we have redefined the classic road bike by revolutionizing three interconnected factors — comfort, fit, and handling/stability — while integrating the latest disc-brake technology and pushing the aero envelope with new Squoval Max tube shapes.
