Product Description
Shimano Ultegra Di2 ST-6870 Dual Control Shifters
- 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:
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.
