Electronic goes affordable.
Shimano's Ultegra Di2 ST-6770 STI levers borrow many features from their flagship Dura-Ace Di2 model with a slightly heavier construction and a refined wire set-up.
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-6770 STI Levers are sold as a pair without electronic wires (SM-EWC2L and SM-EWSD50 are available separately). 313g/pair.
Note: The ST-6770 Levers are not compatible with Dura-Ace 7970 series Di2 components or wires.
