Shimano Dura-Ace Di2 Frame Cable Sets (External)

To ensure that the signal goes from the shifter to the derailleur’s, the reliability of the electric cable has been proven by repeated field tests in various riding conditions, including extreme temperatures, rain, mud, and cobble stone roads.

The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts.


  • Dura-Ace Di2 requires 2 cables: a handlebar cable set to connect the shifters to a battery indicator junction box or FlightDeck, and the other to connect the handlebar cable to the battery and derailleur’s. This battery to derailleur cable is available for internal or external routing in different lengths allowing for various frame sizes
  • External cable sets are ideal for upgrading your current bike to Dura-Ace Di2 if it does not feature the internal cable routing option
  • Internal cable sets are for bikes specifically designed for Di2 to ensure clean lines and minimal rider interference
  • External cables are available in varying lengths, there is no need (or facility) to cut these cables - 790mm and 875mm
  • Reliable and secure water resistant connectors

A 2 year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).
