Shimano EW-SD50 E-tube Di2 Electric Wire - Length: 550mm

When you convert over to Di2 gearing it is more then just your gearing which you are changing over, it is your whole style of riding. Before you get on your bike however you will need to connect all those cables up and this is exactly what the EW-SD50 electric wires are for. The cables are fully removable and allow you to get the correct lengths of cable to run between the indicator junction box or wireless units. The cables are fully water resistant and can be routed through the frame.
