The RX717 series, introduced as a second tier below the higher-end RX820 and RX827 groupsets, includes a right-side dual control hydraulic disc brake lever, two left-side brake-only lever variants, and a rear derailleur. All components operate on Shimano's fully wireless Di2 platform, which provides precise and rapid shifting while maintaining compatibility with the company's 12-speed wireless systems across road and mountain bike lines, including GRX, Dura-Ace, Ultegra, 105, XTR, Deore XT, and Deore models.
