Gravel cycling is not meant to be overly complicated. The heart and soul of cycling’s drop bar, dirt road discipline is rooted in simplicity, inclusivity, and adventure. No ride is out of bounds. All are welcome to join. Gear should be functional and reliable but need not break the bank.
That’s why whether you’re a grizzled gravel cycling veteran or brand new to the road (or trail) less traveled, you’ll appreciate the latest iteration of SHIMANO’s groundbreaking—and industry-first-gravel-specific GRX component group. Designed to help you get the most from your next unpaved adventure, RX820 delivers top-tier performance without an over-the-top price.
SHIMANO GRX 1x12 UNSTOPPABLE
If all-day—or multi-day—adventures heavy on climbing are your thing, the new RX820 1x12 UNSTOPPABLE option with SHIMANO’s wide-range, 10-51T cassette offering is ideal. Paired with a 40T chainring, you'll never run out of gears, even on the steepest jeep road or high mountain ascent. And like the 10-45T, 1x12 option, this group features an integrated SHADOW RD+ chain stabilizer for optimal chain security and an ON/OFF switch, making wheel removal quick and easy if you happen to puncture.
Both 1x12 options utilize Micro Spline, SHIMANO’s lightweight aluminum freehub design that seamlessly integrates with 10-tooth top gears and features smaller, more widely spaced splines that limit cog damage.
SHIMANO GRX RX820 Brakes
Alongside this suite of gravel-optimized gearing options and the new RX880 wheel is the new ST-RX820 brake/shift levers. Specifically designed for use with flared handlebars that are a gravel-cycling staple, the new lever body design features anti-slip texturing on the tops and dramatically improved ergonomics that lessen pressure on your palms. Together, these changes increase comfort and control so you can fearlessly tackle tricky terrain or focus on the rolling gravel road ahead.
The new GRX brake levers feature SHIMANO’s Dual Control setup with its light and responsive mechanical 12-speed shifting. The new 1x12 groups include two options for the left lever: a brake lever-only model and a dropper-specific option that seamlessly integrates braking and dropper post actuation for fast and effortless operation. This kit will come with the brake lever-only model, but we are always open to special orders.
Enhanced chain security and quieter shifting for gravel riding
With its integrated chain stabilizer, the SHIMANO GRX rear derailleur delivers quieter shifting and more secure chain management in rough terrain. The RD-RX822-SGS is compatible with 10-51T, 12-speed SHIMANO MTB cassettes, meaning you’ll never run out of gears even on the steepest jeep road or high mountain singletrack ascent. And the chain tensioner has an ON/OFF switch for easy wheel removal.

The FC-RX820-1 comes in 170, 172.5, and 175 mm crank arm lengths, providing an additional level of customization.
