The Shimano Dura-Ace ST-7900 Shifters are top of the line shifters built to give you nothing but the best performance during every one of your rides. Shimano decided to give their last Dura-Ace shifters an overhaul and this is the result. The new ergonomic design of the Dura-Ace ST-7900 Shifters makes these some of the most comfortable shifters on the market today. To help give it some of the best performance available, Shimano has given the Dura-Ace ST-7900 unidirectional shifting levers that help decrease the stroke and make shifting faster. The brake levers are crafted out of carbon fiber and the shifters come with a titanium clamp and fixing bolt, all of which make these shifters light and durable. If all of these features weren't enough, the Dura-Ace ST-7900 Shifters also feature built-in buttons that make them wireless FlightDeck compatible. The Shimano Dura-Ace ST-7900 Shifters are designed to work with Shimano 10 speed double drivetrains. Includes shifter cables.
