Shimano Shifter Switch SW-R9160 Dura-Ace DI2 310602-05 • Serviceable precision pulleysEasy to push the thumb switch when gripping the top of the TT extension. A single programmable shifter button in each unit, designed to fit cleanly into aerobar extensions. Works perfectly with Shimano's Di2 Synchro Shifting: each "up" shift moves to the next gear ratio considering both front and rear derailleurs, each "down" shift does the reverse. Requires Shimano 9100 Di2 drivetrain. Can be installed as sole shifting point or used in conjunction
