Description

The SHIMANO GRX RX822 1x12V Groupset is designed for cyclists seeking versatility and performance on road and gravel alike. Its 40-tooth chainring paired with a 10-51 cassette offers a wide range of gears, ideal for riding comfortably on the flat, tackling rolling paths or climbing long ascents.

Thanks to SHADOW RD+ chain stabilisation, the SHIMANO GRX RX822 1x12V Groupset ensures optimal chain retention and precise mechanical shifting both front and rear. The close-ratio steps on the cassette allow subtle cadence adjustments, perfect for sporting rides or long adventures on varied terrain.

Compatible with 700c wheels via the proven Microspline freehub body, this groupset ensures straightforward integration. The ergonomic levers with Dual Control configuration offer confident control, with anti-slip texture and improved grip, even on rough terrain.

Designed for flared handlebars and modern gravel riding, this complete groupset optimises comfort, reliability and precision. The SHIMANO GRX RX822 1x12V Groupset allows every ride to be approached with confidence, combining robustness, control and efficiency across all terrains.
