SHIMANO SM-EW79A-E ST-7970 DURA-ACE DI2 DROP HANDLEBAR CABLE STIS NON-FLIGHT DECK

Shimano SM-EW79A-E ST-7970 Dura-Ace Di2 drop handlebar cable for STIs (Non-Flight Deck)

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

The handlebar cable set is for use without a FlightDeck computer; instead using a simple junction box to display battery life

Handlebar cables should not be cut to size or modified in any way

Reliable and secure water resistant connectors

Comes boxed and with fitting instructions
