SHIMANO Expands GRX Groupsets with New RX717 Components

SHIMANO has expanded its range of GRX groupsets with the addition of its latest RX717 components, offering Di2 electronic shifting to more gravel cyclists than ever before.

“Gravel cycling is about adventure, not exclusivity. Whether you’re chasing horizons, exploring rugged backroads, or rolling out for a weekend ride, SHIMANO believes everyone deserves reliable, high-performance gear. Guided by our United in Gravel ethos, SHIMANO continues to deliver gravel-specific components that fit every rider and every budget,” says SHIMANO.

The new series of 12-speed GRX components utilizes SHIMANO’s lightning-fast Di2 electronic shifting platform. The RX717 range includes 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 any off-road adventure.

SHIMANO GRX RX717 1 x 12-Speed Key Features

• 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, SHIMANO 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. Key features include:
