The Cervélo R5ca is an ultralight road bike that represents a pure focus on climbing performance and refined ride quality. Its carbon frame is engineered for exceptional stiffness-to-weight, delivering sharp acceleration and efficient power transfer on steep ascents while maintaining precise, responsive handling. This build pushes weight savings even further with a wireless SRAM Red eTap drivetrain paired with a THM Clavicula SE carbon crankset and Rotor Qarbon chainring. A Lightweight Ventoux carbon wheelset with carbon hubs keeps the bike incredibly responsive, while THM Fibula carbon brakes, a Darimo carbon handlebar and seatpost, and a Smud carbon saddle complete an uncompromising, weight-conscious build. The result is a highly specialized road bike built for riders who prioritize minimal weight, direct power transfer, and a distinctly refined ride feel.
