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.
Please Note:- E-tube is a two prong system and is NOT cross compatible with older Dura-Ace 7970 Di2 wiring.
