EW-SD50L Di2 E-Tube Wire 1600mm

This is the Shimano EW - SD50L Di2 E - Tube wire with a length of 1600mm. It's part of Shimano's advanced E - Tube technology. The frame grommets for E - tube internal - wiring compatible frames are sold separately, check out the Shimano Frame Grommet Kit for extra parts. The Ultegra Di2 wires use Shimano's e - tube system, a two - prong setup that's not compatible with Dura - Ace 7970 Di2 wiring. These e - tube wires can be used for both internal and external applications, offering great flexibility.

Using this Shimano EW - SD50L Di2 E - Tube wire is easy. First, figure out if you're using it for internal or external wiring in your bike. If it's internal, you'll need to get the Shimano Frame Grommet Kit separately. When connecting, make sure you're using it with the right components, as it's not compatible with Dura - Ace 7970 Di2 wiring. For maintenance, keep it clean and dry. Avoid bending it too sharply, as this can damage the wire. If you notice any signs of wear or if the connection seems loose, it might be time to replace the wire.
