Shimano has announced a selection of new GRX RX825 Di2 components including newly designed dual control levers, 2 x 12-Speed GRX electronic shifting, and a Di2-equipped Shadow RD+ Rear Derailleur. The Japanese brand says these latest additions to its gravel bike groupset will deliver "optimal performance and enhanced gearing options" to the best gravel bikes.
GRX launched as the first gravel-specific groupset in 2019 and saw its first major evolution last year with the release of the mechanical 12-speed Shimano GRX RX820. We noted at the time that a fully electronic GRX Di2 option would likely come soon, and our crystal ball speculating has now come true.
