Shimano Di2 Inline Wireless Unit - EW-WU111 One Color, One Size

Product Review

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.

Shimano Electronic Intelligence System:
Allows accurate and effortless shifting in challenging circumstances, like when you have cold hands or when you're completely exhausted
Shifting performance is never affected by contaminated or stretched cables, since the shifting signal is transferred electronically
Operating buttons work similarly to mechanical Dual Control Levers, so you don't need to learn a new system
SLR-EV with dual symmetric pivot brake caliper:
