Shimano ST-6870 Ultegra Di2 E-tube STI Shifters make shifting easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear.

The shift buttons are located in a near identical place to the position if using a mechanical Shimano STI and these shifters are for use with E-tube electric cables. The set weighs in at just 295 grams a pair.
