Shimano Dura Ace EW-7970 Di2 Derailleur To Battery External Cable Set
Shimano Dura Ace EW-7970 Di2 Mech To Battery External Cable Set
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, 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 7970 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 derailleurs. 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 7970 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. Features External cable set.
Reliable and secure water resistant connectors. Available in varying lengths... more details.

Shimano are a Japanese manufacturer primarily known for their cycling components, and to a lesser extent shoes and clothing. Founded in 1921, Shimano is widely believed to be the largest cycling component manufacturer in the world, having reached this status through a combination of innovation, reliability and value for money. Whatever your style of riding, whether it be road or MTB, Shimano will have a component range to suit your level and budget, from the low end Alivio and Tiagra to the professional standard XTR and Dura-Ace. Over the years, Shimano have revolutionised bicycle gear, brake and pedal systems, such as the recessed SPD, Hollowtech crank arms and smooth shifting Hyperglide sprockets. Initially their component range faced competition from Suntour, whereas nowadays their primary rivals for market share are SRAM and Campagnolo. If you wish to save money on their components and apparel, please visit my Shimano section, where I list as many money saving deals as I can find.
