The Cervelo Down Tube Port Blanking Plug Wireless is a frame-specific accessory designed to cover the down tube’s wireless routing port when external cable or hose routing is not used. It protects the frame’s internal routing passage from dirt, moisture, and debris ingress, helping preserve frame integrity and maintaining a clean appearance.

This blanking plug is engineered to fit precisely into the designated wireless port on compatible Cervelo frames. Its secure fit helps prevent unwanted material from entering the frame’s interior, which can otherwise lead to corrosion or noise over time. Installation is straightforward and involves pressing the plug into the port until it seats flush with the down tube surface.

Constructed from durable materials suited to road and mixed-surface riding environments, the plug resists wear from vibration and environmental exposure. Its low-profile design preserves aerodynamic lines and prevents interference with clothing or accessories. The blanking plug is intended for riders who are not using internal wireless routing on their down tube but want to maintain frame protection and a tidy aesthetic.
