Ultegra Di2 wires use Shimano's e - tube technology. This e - tube is a two - prong system and isn't cross - compatible with Dura - Ace 7970 Di2 wiring.

Using this Shimano EW - SD50 Di2 E - Tube wire is easy. You can use it either inside or outside the frame according to your needs. But remember, the frame grommets for internal wiring are sold separately, so you'll need to get them if you plan to do internal wiring. Also, note that this wire won't work with Dura - Ace 7970 Di2 wiring because of the different e - tube system. When it comes to maintenance, keep it clean and dry. Avoid bending it too sharply as this might damage the internal wires. If you notice any signs of wear or if it stops working properly, it might be time to replace it.
