- for internal junction box (EW-RS910), frame mount: 5 x EW-SD50 power cables (1 x to EW-RS910 = junction A, 1 x to SM-JC41 = junction B, 1 x to front derailleur = FD, 1 x to rear derailleur = RD, 1 x to battery) + 1 x EW-JC130 Y-cable junction box (connection between EW-RS910 and STI) + 1 x EW-JC200 junction box (connection between EW-JC130 and EW-SD50 to EW-RS910)***

* For the correct cable length ,the following frame measurements are needed:
- Length of down tube = distance between bottom bracket and stem

- Distance between bottom bracket and front derailleur
- Distance between battery and bottom bracket
- Distance between rear derailleur and bottom bracket
- Distance between bar end and the next shifter (STI)
For Y-cable: 1. distance between stem and bar end with EW-RS910, 2. distance between stem and bar end and STI on the side without EW-RS910 (3. = distance between stem and wireless unit / EW-JC200 is determined, compare this to the cable length of EW-JC130 Y-cable junction box)
