"Earlier this month, Shimano unveiled the newest and most affordable wireless 1x gravel drivetrain - GRX RX717. This new wide-range drivetrain borrows all the tech that makes the latest 12-speed Di2 MTB drivetrains so spectacular. Thanks to a few material choices and minor tweaks, the brand can maximize cost without compromising reliability or functionality. What's New, Di2? The new GRX bits use the same familiar design language as seen on all the other new Di2 offerings from both the road, gravel, and MTB sectors."
"Visually, the new RS717 and RX715 shifters take design inspiration from Shimano's road offerings. In contrast, the derailleur takes the latest designs of the XTR M9220 and GRX RX827 and tweaks them slightly with new construction to keep costs down and performance up. The shifters, which use the same taller hood and lever design as 105, Ultegra, and Dura-Ace, feature all the same functionality that riders demand for a 1X drivetrain,"
Shimano introduced the GRX RX717 as a more affordable wireless 1x gravel drivetrain that leverages proven 12-speed Di2 MTB technology. The system combines derailleur, crankset, cassette, and shifters into a wide-range wireless package designed for reliability and compatibility without requiring major bicycle modifications. RS717 and RX715 shifters draw road-inspired tall-hood ergonomics from 105/Ultegra/Dura-Ace while omitting auxiliary hood buttons and textured grips to lower cost. The rear derailleur incorporates XTR M9220 and GRX RX827 design elements with revised construction to reduce price while maintaining shifting speed and robust performance.
