Shimano 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 brake set consisting of the BL-RX610-L brake lever for confident handling and the BR-RX400-F hydraulic disc brake caliper for consistent braking performance. For a smooth and at the same time easy maintenance provide the proven One Way Bleeding Bleeding system and the Easy Hose Joint System, which greatly facilitates the brake line replacement.

Gravel for Everyone. With its Gravel-specific ergonomics, the GRX BL-RX610 brake lever stands for unsurpassed comfort on mixed terrain. Whether touring or racing, the structured grip shape combined with the non-slip surface of the brake lever blade noticeably increases control on uneven terrain. The brake lever, which has been optimized for 1-speed drivetrain systems, is adjustable in reach.

Shimano GRX BR-RX400-F disc brake caliper

Attack the toughest terrain without hesitation with the GRX BR-RX400 hydraulic caliper. Its 2-piston design not only provides more control on rough terrain, but also offers stable braking performance in all conditions. The disc brake caliper is attached directly to the frame or fork via Flat Mount system.

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.
