11-speed electronic shifting goes affordable.

Shimano's Ultegra Di2 ST-6870 STI levers benefit from the inevitable trickle down from the flagship Dura-Ace Di2 model, including 11-speed shifting.

The Di2 does away with shift cables, so these cutting edge STI levers provide lightening fast gear changes with less than 2mm of lever travel required per throw. This means immediate response in any competitive scenario -- shifting is as easy as a mouse click.

The shifter ergonomics are lifted straight from the mechanical Ultegra model for proven comfort, though the hoods have been made slightly narrower, as the Di2 levers don't need to accommodate shift housing. Unlike the mechanical levers, both up and down shifts are made using the two pads behind the brake lever. Updated pivot placement makes the brake lever itself easier to access from any handlebar position and adjustable reach ensures a comfortable fit for riders of all sizes.

The Ultegra Di2 ST-6870 STI Levers are sold as a pair without electronic wires.

Note: The ST-6770 Levers are only compatible with Dura-Ace 9070 series Di2 11-speed components or wires.
