Trickling-down tech is happening faster each year, and before the end of 2025, Shimano has already introduced the GRX RX717 component lineup, bringing robust 12-speed GRX Di2 electronic shifting to a more affordable price point…

GRX Di2 RX827 was announced back in June, and already, Shimano has rolled out its new GRX RX717 Di2 12-speed GRX components. These components utilize Shimano’s lightning-fast Di2 electronic shifting platform at a more affordable price point.
Included in this component release is a right-side Dual Control lever, two left-side brake-only lever options (one GRX-branded, the other Shimano-branded), and the GRX RX717 rear derailleur, which, when paired with a 10-51T 12-speed cassette, delivers the range, reliability, and shifting speed needed for dirt road riding and racing.
GRX RX717 Features
Reach Adjust Levers – Dial in personalized ergonomics and feel
Long-Lasting CR1632 Batteries – Up to four years of use, easy to replace
E-TUBE PROJECT Cyclist App Compatibility – Customize shift buttons and features in the app
GRX RX717 Notes
Fully Wireless Di2 Platform – Designed for ultimate reliability, the wireless Di2 system offers fast, precise shifting and compatibility with all Shimano 12-speed wireless shifters (GRX, Dura-Ace, Ultegra, 105 Di2 drop bar options, as well as XTR, Deore XT, and Deore flat bar Di2 models)
Robust Gravel Drivetrain – Borrowing its design from Shimano’s MTB Di2 line, the RX717 rear derailleur features the same low-profile design, skid plate, protected battery, and Automatic Impact Recovery function.
Expanded Versatility – Added GRX component options allow riders to optimize performance based on terrain, style, and personal budget.

GRX RX717 Levers: Customizable Control at your Fingertips
A highlight of the lineup is the GRX 12-speed ST-RX715-R Di2 Hydraulic Disc Brake Dual Control lever. This right-side lever offers a more affordable 1 x 12-speed wireless shifting option, combining Shimano’s precise shifting with powerful braking performance.
