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 ST-RX610 brake/shift lever

Gravel for Everyone. The GRX ST-RX610 STI lever stands for unsurpassed comfort and a light, responsive shifting behavior in mixed terrain. Whether touring or racing, the textured grip shape combined with the non-slip surface of the brake lever noticeably increases control on uneven terrain. Adjustable in reach and free stroke.

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.
