EW-SD50 Di2 E-Tube Wire 700mm

This is a 700mm Shimano EW - SD50 Di2 E - Tube wire. It uses Shimano's e - tube technology. The Ultegra Di2 wires with e - tube, a two - prong system, aren't cross - compatible with Dura - Ace 7970 Di2 wiring. All e - tube wires can be used for both internal and external applications. Frame grommets for E - tube internal - wiring compatible frames are sold separately. Check out the Shimano Frame Grommet Kit for extra parts.

Using this Shimano EW - SD50 Di2 E - Tube wire is straightforward. You can install it either inside the frame for a clean look or outside if that's more convenient. Just connect it to the appropriate components according to your bike's setup. When installing, be careful not to bend the wire too sharply as it may damage the internal connections. Also, since the Ultegra Di2 wiring isn't cross - compatible with Dura - Ace 7970 Di2 wiring, make sure you're using the right one for your bike. For maintenance, keep the wire clean and dry. You can use a soft cloth to wipe it down. If you need to run the wire inside the frame, you'll need to buy the frame grommets separately, so plan ahead for that.
