The Cervelo Seatube Open Di2 Grommet 2014–Present is a frame-specific accessory designed to seal and support electronic shifting wire routing at the seat tube entry point on compatible Cervelo frames. It protects the internal frame cavity by covering the Di2 wire port when wiring passes through, helping prevent moisture, dirt, and debris from entering and affecting shifting performance or frame integrity.

This open grommet is engineered to match the contour and dimensions of the designated Di2 port on seat tube locations across Cervelo models from 2014 to the present. It provides a precise fit that maintains cable alignment and minimizes movement, reducing wear on electronic wiring and preserving clean internal routing paths. Installation involves seating the grommet securely into the frame opening around the wire entry point.

Constructed from a durable and flexible material, the grommet resists wear from vibration and environmental exposure while maintaining its protective function. Its open design accommodates electronic wires without compromising sealing properties, and its low profile preserves frame aesthetics. The part is intended for riders using electronic shifting systems who require reliable protection for internal Di2 routing through the seat tube.
