Shimano Dura Ace Di2 ST-9070 STI shift levers
The Shimano Dura Ace Di2 electronic shift-brake levers are fitted with carbon brake levers. Shifting taken to a whole new level. Extremely fast and precise. Thanks to electronic transmission of shift commands, these are executed without delay. Operation is similar to that of the mechanical STI levers; shifting is done at the touch of a button. The new 11-speed shifters are also equipped with the programmable Multishift function
The brake levers are made of carbon and the mechanical shifting components are eliminated, meaning the Di2 ST-9070 shift-brake levers save 123 grams compared to the mechanical Dura-Ace version. That is: 255 versus 378 grams
To operate the Dura-Ace Di2 shift levers, the EW-SD50 and SM-EW90 cable sets for Shimano’s Di2, complete with Quick Mount battery holder and mounting hardware, are also required. The EW-SD50 cable set features connectors for the rear derailleur, front derailleur and battery pack. Additionally, the SM-EW90 cockpit junction port is required for connecting the Dura-Ace Di2 STI shifters.
