Shimano Dura-Ace Di2 EW-7970-7975 Rear Wire Kit Info
The Shimano Dura-Ace Di2 EW-7970-7975 Rear Wire Kit is the factory-spec wiring solution for connecting Shimano's 7970 and 7975 Di2 electronic groupsets. Designed to route from the rear derailleur junction, these wires maintain a clean, reliable signal connection — the kind of detail that keeps your shifting crisp and consistent over long miles.
Available in several length and configuration variants to suit different frame routing setups, this kit ensures you're using the correct Shimano Di2 wiring rather than working around a mismatched length. A straightforward replacement or build component for any mechanic working with first-generation Dura-Ace Di2.
