Shift. Anytime.

With the advent of the Dura-Ace TT brakes with integrated shifters, triathletes and time trial riders who race technically challenging courses rejoiced. Now, the same versatile technology has been handed down to the Ultegra line. The Shimano Dura-Ace Di2 ST-9071 11-Speed TT Brake/Shift Levers and Shimano Ultegra Di2 Remote TT Shifter Set is sure to lend its name to many personal records in the near future.

Although it may seem redundant to place two sets of shifters on your aerodynamic time trial or triathlon bike, it actually makes a great deal of sense. Even though frame design and wheel choice play an important role in slipping cleanly through the air, if you move around while riding, you are negating those clean slipstreams. And, if you've raced technical or hilly courses where you need to hold the brakes to make tight corners, but also need to shift mid-turn or during a climb, you've experienced that awkward reach toward the bar ends. Integrating the electronic shifters into the brake levers eliminates that motion entirely so that you are able to concentrate on taking clean fast lines through the course.

The ST-6871 is a dual button design for bikes with double chainrings. Your left brake lever has two buttons that control the front derailleur and the right controls the rear. The Di2 electronic shifting ensures effortless and perfect shifting every time. The alloy levers feature an adjustable reach.

The Shimano Di2 TT Brake/Shifters and Bar End Shifter Set includes both right and left levers, brake cables, and housing ferrules.

Can you use these as standalone brake/shifters on, say, a bullhorn handlebar?
