Shimano Di2 SW-RS801-S Sprinter Switches for Drop Handlebar

Shimano Di2 SW-RS801-S Sprinter Switches for Drop Handlebar This twin pack of Shimano Di2 SW-RS801-S Sprinter Switches are usually positioned on the drops of a drop handlebar to facilitate gear shifting when in an all-out gallop for the finish line. They operate the rear derailleur only; with one taking care of upshifts and the other moving the chain down the cassette. They are directly clipped onto the handlebar and usually part-wrapped over with bar tape to provide a neat; professional finish. Connection to the Dura-Ace ST-9270 STI levers is taken care of by the included SD-300 series 100mm long wires.
