The new R5 introduces the Rca's frame profile to the R-series line-up. Light and stiff, the R5 now offers a 7.4 Watt aero advantage thanks to the latest Squoval family of tube shapes. With a 9.5% stiffer bottom bracket compared to the last generation R5, this bike is perfect for acceleration, climbing or on the attack, while a 15% increase in torsional head tube stiffness offers improved handling. The R5's new fork shape improves side stiffness and front compliance while maintaining aero performance. Future-proof cable routing is ready for mechanical and electronic.
