To Outfit Your&Nbsp;Ultegra&Nbsp;Di2 Bike, You'Ll Need Five Distinct Wire Sections -- Front Wire, Front Wire To Junction Box, Front Derailleur Wire, Battery Wire, And Rear Derailleur Wire. This Is The Ultegra Di2 6770 Rear Derailleur Wire And It'S Available In Three Sizes -- Short, Medium, And Long. The Rear Derailleur Wire Is The Portion Of The System That Connects The Rear Derailleur To The B Junction. One Nice Thing About The Ultegra Di2 System Is That All The Wires Are The Same, Save For The Length. This Means That All The Connections Are Identical, And It Doesn'T Matter If Your Frame Has Internal Or External Routing. The Ultegra Di2 6770 Rear Derailleur Wire Lengths Are As Follows: Short - 500Mm, Medium - 550Mm, And Long - 600Mm. Since Most Road Bike Chainstays Are Within A Few Millimeters In Length, The Size Determination Depends On Your Planned Location Of The B Junction. Remember, Too Long Is A Workable Option; Too Short And You'Ll Be Watching Race Videos At Home On The Couch.
