Shimano Shifting Kit - GRX RX610 - 2x12 Speed

Shimano GRX – United in Gravel

Gravel is the great equalizer. It doesn't matter who you are, where you're from, or where you want to go. Gravel celebrates individuality. It brings people together in a shared passion. It lays the foundation for friendships and creates memories for eternity. Whether you travel a kilometer or a hundred. With or without professional equipment. With a 10, 11 or 12-speed gearbox system. On asphalt roads, forest roads, secondary roads – or no roads at all. It doesn't matter why you're out there, it just matters that you are.

Gravel for Everyone. The 12-speed mechanical components of the Shimano GRX RX610 series are perfectly suited for use on mixed terrain. As a result, the STI ST-RX610 lever not only offers light and responsive shifting, but also unsurpassed comfort and maximum control on uneven terrain thanks to the textured shape of the handle and the non-slip surface. In combination with the BR-RX400 caliper, which ensures stable braking performance in all conditions, even the most difficult terrain can be tackled without hesitation.

Meanwhile, the FC-RX610 crankset combines low weight with improved efficiency, so you always cut a fine figure even on rough surfaces. Of course, the large gear ratio, which adapts to the different demands of gravel use, and the tight gradation with smaller step steps, which ensures a uniform cadence, should also be highlighted. The front and rear derailleurs are also optimally matched to the crank arm and are characterized by a light, harmonious and at the same time natural shifting behavior. While the FD-RX820 front derailleur impresses with its simple and precise adjustment, also thanks to the Toggle Link structure, the RD-RX820 rear derailleur shines with its integrated chain stabilizer, which noticeably reduces the noise level when shifting.
