The Shimano GRX Groupset: Variety for Every Gravel Scenario
The Shimano GRX series is the world's first groupset developed specifically for gravel bikes. It combines the proven technology of road bike and mountain bike shifting to offer you optimum off-road performance. The outstanding feature of the groupset is the Shimano GRX rear derailleur with Shadow RD+, which stabilizes the chain even on uneven terrain. The Shimano front derailleurs in the GRX series also have additional capacity. And thanks to the gravel ergonomics of the lever blades and versatile gear ratio options, you are definitely equipped for any gnarly scenario.
The Shimano GRX range includes several series with specific features such as a 1x or 2x crank for different needs and budgets:
- GRX RX 800 series: the high-end groupset from Shimano, comparable to the Shimano Ultegra series for road bikes. It is available in 11- and 12-speed versions and offers both mechanical and electronic Di2 options.
- GRX RX 600 series: The mechanical mid-range groupset offers a wide range of 11-speed options. It is robust and reliable, comparable to the Shimano 105 road bike groupset.
- GRX RX 400 series: Mechanical 10-speed groupset for beginners, at the level of the Shimano Tiagra road bike groupset. It offers reliable performance at an attractive price.
For even more comfort, a finer gear gradation and shifting precision, you can also opt for the electronic Di2 version of the GRX 2x12-speed series. The electronic shifting guarantees smooth gear changes and a fast response time, which is particularly advantageous in demanding conditions.
Shimano GRX 12-Speed Shifting: 3 Variants for Different Riding Styles
An important aspect of the GRX series has always been its versatility. Shimano GRX cranks, rear derailleurs, brakes and cassettes are designed so that they can be easily combined and adapted to different configurations of a gravel bike. The Shimano GRX 12-speed series takes this into account and also expands your shifting options. The engineers at Shimano rely on three different 12-speed drivetrains that offer optimized gear ratios depending on your needs and use:
- Shimano GRX 1x12 with a close ratio: optimal if you want to maintain a constant cadence even on uneven terrain. The configuration uses a 10-45T cassette and chainrings with 40 or 42 teeth.
- Shimano GRX 1x12 with a wide ratio: This variant offers you a maximum range with a 10-51T cassette, ideal for long climbs or difficult terrain.
- Shimano GRX 2x12 shifting: All-road-oriented option with an enormous gear range and narrow gear steps, available mechanically or as a Di2 version.
Compatibility with existing wheels and the use of micro spline technology from the MTB sector for the freewheel on the rear hub allow you to quickly upgrade your gravel bike. In addition, the brake lever shape for handlebars with flare has been optimized for the 12-speed series, the metering range of the lever blades has been extended and the noise development in difficult weather conditions of the Shimano GRX brakes has been reduced.
