Di2 hidden wires, how many, what lengths?
by John42

Shimano Di2 EW-SD50 E-Tube Wires; YOU NEED about 6 or 7 various lengths. All the components clip together:

It helps to understand the lengths you require, longer is better, if you have room to stuff extra in down-tube. The line through your handlebars may be longer.

Counted 6 wires: In the SEAT TUBE, Battery-WIRE-wireless transmitter-WIRE-Junction Box- Wire-Rear Derailleur. Same Junction Box -WIRE-Plug in device-WIRE-R Shifter- Wire- L Shifter

YES, To connect SHIFTERS: I drilled 2 exit holes (near the plug end) in my carbon handle bars, maybe 8cm from end (Mad Man) or consider other handle bars.

It is just a cable... but you need one to add the Di2 EW-WU111 In-Line Wireless Transmitter

It is just a short cable, but very helpful to add the wireless transmitter inline without having to cut any cables or wires.

I think this should be required for any bike with Di2. Who wants to look at blinking lights to see if your battery is flat? Also enabling the little buttons under the brake hoods is convenient if your Garmin screen andor hands are wet. Only downside, this stuff is expensive for what it is.
