GRX RX710/RX717 – Featuring More Affordable Di2 Options Gravel cycling is about adventure, not exclusivity. Whether exploring new horizons, touring off paved roads, or simply enjoying a weekend ride, everyone deserves reliable and high-performance equipment. True to this belief and in line with the motto "United in Gravel," Shimano has developed components that suit every rider and every budget. With the GRX RX717 series, even more Gravel athletes can now benefit from an electronic Di2 shifting system that combines lightning-fast response with durability. Shimano GRX BL-RS717 brake Lever Customizable Control at your Fingertips. Thanks to the same shape and ergonomics, the BL-RS717-L is the perfect complement to the ST-RX715-R brake/shift lever. The brake lever, which is intended for mounting on the left side of the handlebar, does not feature any shift electronics, making it a lightweight and simple option for all situations where less is more. Just like its dual-control counterpart for the right handlebar side, the hydraulic disc brake lever, developed for the 1x12-speed GRX drivetrain system, can be optimally adapted to personal preferences with the help of an easy-to-use reach adjustment function.
