GRX – United in Gravel
Gravel is the great equalizer. No matter who you are, where you come from or where you want to go. Gravel celebrates individuality. It welds together in a shared passion. It lays the foundation for friendships and creates memories for the ages. Whether you ride one kilometer or a hundred. Whether with professional equipment or without. With a 10-speed, 11-speed or 12-speed gear system. Whether on paved roads, forest roads, back roads – or no roads at all. It does not matter why you are out there, all that matters is that you are.
Shimano GRX disc brake set consisting of the ST-RX610 lever and the hydraulic BR-RX410 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 ST-RX610 brake/shift lever
Gravel for Everyone. The GRX ST-RX610 shift/brake lever stands for unsurpassed comfort and light, responsive shifting behavior in mixed terrain. Whether touring or racing, the structured grip shape combined with the non-slip surface of the brake lever noticeably increases control on uneven terrain. The dual control lever for 2x12-speed drivetrain systems is adjustable in reach.
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.
Dual Control Lever (DCL) | The Shimano DCL levers combine braking and shifting functions in one control unit for easy as well as comfortable operation. In raising the standard of performance, their innovative ergonomics are even more important to consider than adding additional gearing. However, the highlight of the STI shifters (Shimano Total Integration) shifters, is the ability to change gears front and rear with just one finger. The Dual Control levers owe this not only to an extremely precise and smooth operation, but also to the same stability for which Shimano's MTB technologies are already known.
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.
