The evolution of perfection. 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. The handlebar cable set is available in two types: one for use without a Flight Deck computer instead using a simple junction box to display battery life; the other is for use with Flight Deck. This handlebar cable set for non-Flight Deck use has specifically been developed to use with the TT spec ST-7971 & SW-7971 shifters & switches. Handlebar cables should not be cut to size or modified in any way. Reliable & secure water resistant connectors.
