Connecting all the components. The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, 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, one front one rear: the front to connect the shifters to a battery indicator junction box or Flight Deck, & the rear to connect the junction box/ Flight Deck to the battery & derailleurs. This battery to derailleur cable is available for internal (EW-7975) or external routing (EW-7970, this product) in different lengths allowing for various frame sizes. External cable sets are ideal for upgrading your current bike to Dura-Ace Di 2 if it does not feature the internal cable routing option. Reliable & secure water resistant connectors. Choose your correct length: EW-7970: External cables are available in three lengths: Large
- 890mm, Medium
- 830mm & Small
- 770mm. Where the cables are routed on the outside of a frame & do not run internally, there is no need (or facility) to cut these cables. If you require an internal rear cable set please purchase the EW-7975, available separately.
