A key concern for gravel riders is a reliable braking system with enough power reserves. The new Shimano GRX 12-speed STI ST-RX610 lever for hydraulic disc brakes offers excellent deceleration performance to maintain control on steep, demanding, or even unexpected descents.

For more price-sensitive customers and to allow for a wider price range for complete gravel bikes, Shimano has updated its 600-series cranks and derailleurs for 1×12 and 2×12 setups, now using technology from the original GRX 800-series components as a result of a “trickle-down” process.

Main features include textured covers and a non-slip coating on the brake levers that enhance control on rough terrain. The new cranksets offer gearing options specifically designed to meet the demands of gravel riding.

The 2×12 cranks have a 46-tooth and a 30-tooth chainring and are available in 165, 170, 172.5, and 175 mm crank arm lengths. The RX610 1×12 crank has the same four crank lengths and is now available with a 38T chainring or even the traditional 40T. These options are paired with a 10-45 or 10-51 cassette.
