Just measure well!! It's easy to get a cable that is too short, so I took the advice of a local mechanic friend, 'get long', and tuck the excess, because getting too short isn't going to do the job. You can make them shorter (tucking) but you can't make them a couple inches longer as the smallest cable is a lot to have to tuck in. I used 1,000 and a 1,200 for most, with a 950 for the front mech.
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.
This cable was the perfect length and took care of the job.
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.
Installed clean and easily
Cable worked get and has tight connection
Uh, what can I say... this is necessary to connect the wireless Di2 module. Is it worth $xx, no way... but a necessary evil.
