Fitting an UltegraDi2 bike requires five different wire sections: front wire, front wire to junction box, front derailleur wire, battery wire, and rear derailleur wire. This is Ultegra Di2 6770 rear derailleur wire and comes in three sizes - short, medium, and long. The rear derailleur wire is part of the system that connects the rear derailleur to the B junction. The Ultegra Di2 system means all wires are the same, saving you length. That is, all connections are the same, regardless of whether the frame has internal or external routing. Ultegra Di2 6770 rear derailleur wire lengths are: short - 500mm, medium - 550mm, long - 600mm. Most road bike chainstays are within a few millimeters long, so the location of the B junction determines the size. Too long is a workable option. If it's too short, you'll end up watching race videos at home on the couch.
