Using this Shimano EW - SD50 Di2 E - Tube wire is easy. First, decide if you want to use it for internal or external wiring on your bike. If you choose internal wiring, remember that you'll need to buy the frame grommets separately. When connecting, make sure it's properly attached as the e - tube is a two - prong system and won't work with Dura - Ace 7970 Di2 wiring. As for maintenance, keep it clean and dry. Avoid bending it too sharply to prevent damage to the internal wires. If you notice any signs of wear or if it stops working properly, it might be time to replace it.
