E-Tube Di2 wires form the connections of a Di2 system. Shimano's E-tube technology, is a weather-sealed system that allows multi-compatibility and expandability of the Di2 system.
Connectors easily click securely into place (always use the approved Di2 wiring Tool) and allow quick install of Di2 e-Tube components.
