Connecting all the components. The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminants, corrosion & stretching, but provides effortless gear shifts. Key

Features: To ensure that the signal goes from the shifter to the derailleurs, the reliability of the electric cable has been proven by repeated field tests in various riding conditions, including extreme temperatures, rain, mud, & cobble stone roads. Dura-Ace Di 2 requires 2 cables: a handlebar cable set to connect the shifters to a battery indicator junction box or Flight Deck, & the other to connect the handlebar cable to the battery & derailleurs. Reliable & secure water resistant connectors. Choose from either options: Option 1: EW-7972: battery to derailleur cable set where the cables use internal down tube routing which then exits around the bottom bracket shell with external front & rear derailleur routing in conjunction with a short battery mount for neat fitment. Option 2: EW-7973: (870mm) battery to derailleur cable set where the cables use internal down tube routing which then exits around the bottom bracket shell then use internal routing in the chainstay for the rear derailleur & up the seatpost tube for the front derailleur in conjunction with a short battery mount for neat fitment. Option 3: EW-7973-2: (1100mm) battery to derailleur cable set where the cables use internal down tube routing which then exits around the bottom bracket shell then use internal routing in the chainstay for the rear derailleur & up the seatpost tube for the front derailleur in conjunction with a short battery mount for neat fitment.
