GRX RX717 is Shimano’s new, wallet-friendly gravel groupset

GRX RX717 is a new series of 12-speed GRX components from Shimano. It runs on the same electronic shifting platform as their more premium Di2 groupsets and features a right-side dual control lever, two left-side brake-only lever options and a rear derailleur.

RX717 matches the gear range possibilities of Shimano’s more opulent drivetrains.

The new components pair with the brand’s 10-51T 12-speed cassette offering that wide range of gearing very much needed for off road riding. It’s a fully wireless system that is also compatible with all of Shimano’s road, gravel and mountain bike wireless shifters.

Borrowing its design from Shimano’s MTB Di2 line, the new GRX RX717 rear derailleur features the same low-profile design, skid plate, protected battery and Shimano’s Automatic Impact Recovery function. The big differentiator looks to be the steel cage on the RX717 derailleur which lowers costs and adds a couple grams.

Although a lower-cost option, the new levers still feature reach adjust, are powered by ‘long-lasting’ (up to four years Shimano tells us) CR1632 batteries. The shift buttons are also fully customizable through the Shimano app. We haven’t had any indication on local pricing (and it will vary from store to store) – but it appears to be about 35% cheaper than the GRX RX827. | More: shimano.com //
