Shimano Dura-Ace Di2 R9200 Groupset

Shimano's 12-speed semi-wireless road groupset launched in 2021. Shift levers run on coin-cell batteries communicating wirelessly; derailleurs wire to an internal seatpost battery. Shimano claims 58% faster rear shifting and 45% faster front shifting versus the R9150. The R9270 hydraulic disc variant uses ServoWave lever technology.
