With a simple, single-button design and a refined, ergonomic shape, the SW-R9160 DI2 triathlon remote shifter offers quick shifting while riding with aero handlebars. Using the SHIMANO SYNCHRONIZED SHIFT program, each handlebar-end shifter can be programmed to shift or downshift with the gear while the DI2 computer decides when to make derailleur chainring shifts for the optimal combination of derailleur and gear.
