The Cervelo E-Wire Closed Grommet is a small frame accessory designed to seal and protect electronic wiring ports on compatible Cervelo frames. It helps prevent moisture, dirt, and debris from entering internal routing passages when electronic shifting cables or wires are not present, preserving frame integrity and maintaining a clean frame appearance.

This grommet is engineered to fit precisely into the designated E-Wire port location, providing a secure, flush seal with the frame surface. By blocking unwanted material from entering the internal cavity, it helps reduce the risk of corrosion or interference that can compromise electronic routing performance or frame finishes over time. Installation involves pressing the grommet into the port until it seats evenly with the surrounding frame area.

Constructed from a durable and flexible material, the closed grommet resists wear from vibration and environmental exposure while maintaining its sealing function. Its low-profile design preserves aerodynamic lines and avoids interference with adjacent components or accessories. The part is intended for riders who are not using E-Wire connections at the port but want to maintain protection and a tidy aesthetic on their frame.
