Shimano DuraAce Di2 Handlebar Cable for STI

To ensure that the signal goes from the shifter to the derailleurs, the reliability of the Shimano DuraAce Di2 Handlebar Cable for STI 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, and the other to connect the handlebar cable to the battery and derailleurs
  • The handlebar cable set uses a simple junction box to display battery life and for initial set up
  • Developed to use with the TT spec ST-7971 and SW-7971 shifters and switches with 400 mm extension cables
  • Handlebar cables should not be cut to size or modified in any way
  • Reliable and secure water resistant connectors
  • Productcode: R1690060
