The Cervelo Downtube Cable Guide Di2/C3, C5, R3 Disc is a frame-specific routing accessory designed to organize and support electronic shift (Di2) and mechanical shift cables along the downtube on compatible Cervelo frames. It provides a stable pathway for cable housing or electronic wires, helping maintain consistent shifting performance and reducing unwanted friction or movement that can impact drivetrain responsiveness.

This cable guide is engineered to align with the downtube’s contour and integrated routing provisions on C3, C5, and R3 Disc frames. By securing the routing path through this high-motion area, it minimizes cable play and potential wear from contact with the frame surface. Proper routing contributes to smooth and reliable operation of both electronic and mechanical shifting systems under varied riding conditions.

Constructed from durable materials suited to road and mixed-surface use, the guide resists wear from vibration and environmental exposure. Its design complements the frame’s structural and aesthetic characteristics without adding bulk or disrupting airflow. Installation follows the frame’s integrated stops or bosses, and correct alignment and hardware ensure secure fitment.... Read More
