Shimano Ultegra Di2 ST 6870 11 Speed Shifters

The Ultegra Di2 ST 6870 11 Speed Shifters look to the innovations pioneered by Shimano's top of the line Dura Ace to provide enhanced shifting performance. The new Di2 ST 6870 hoods features a slimmer, Dura Ace like profile that offers easy lever accessibility, and the redesigned lever blades and paddles offers more positive interaction from the hoods or drops. Shimano has also widened and re textured the shift buttons, and the 10mm of reach adjustment for the levers makes shifting effortless when you're buried in the drops on a long descent or during a sprint finish. Like Dura Ace, the Ultegra Di2 ST 6870s now enjoy the same fully programmable shifting technology. E Tube technology allows you to select five different shifting speeds giving you a customizable ride quality that is specific to your riding style. And with the single wire E Tube connection, Shimano makes this a tidy application.
