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 Squoval 3 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, electronic and hydraulic, and a rear dropout cable exit provides a straight, low-friction path for rear derailleur cable routing.
