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.
Hydraulic Shimano GRX disc brake set consisting of the BL-RS717 brake lever and the BR-RX410 brake caliper. Smooth and simple maintenance is ensured by the proven One Way Bleeding system and the Easy Hose Joint System which makes brake hose replacement considerably easier.
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.
Shimano GRX BR-RX410 disc brake caliper
Thanks to improved modulation and a faster-responding pressure point, the hydraulic 2-piston brake caliper of the RX410 series gives Gravel athletes a completely new feeling of control. The 10 % wider brake pad spacing also reduces the occurrence of annoying brake noise, making the Flatmount caliper noticeably quieter than the predecessor model despite its flatter design.
J-Kit (Easy Hose Joint System) | For brake systems with J-Kit brake hose connection, the brake lever has an integrated squeeze seal (olive), which makes the installation and removal of the brake line much easier overall.
Ice Technologies | In order to keep the braking power at longer continuous operation consistently high, Shimano has developed the Ice-Tech cooling technology for brake discs and brake pads. Brake pads with Ice Technologies feature cooling fins made of aluminum, which better dissipate heat. In conjunction with the optimized radiation properties of the rotor, this results in a longer durability of the pads, while brake noise and fading are minimized.
