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.

For riders seeking the best of both worlds, the new 2x12 RX820 UNDROPPABLE drivetrain is the choice. Utilizing a gravel-optimized 48/31 front chainring paired with an 11-34 or 11-36 cassette, this setup delivers an ultra-wide gear range so you can spin a comfortable cadence whether cruising the flats, smashing endless dirt road rollers, or tackling a massive backcountry climb.

This setup delivers precise mechanical shifting both front and rear and an integrated SHADOW PLUS chain stabilization for ultimate security over bumpy terrain.
The gravel-specific 2x12 option maintains tighter rear cassette gear steps, ideal for subtle cadence changes during competitive racing and spirited weekend group rides.
And the 2x12 setup seamlessly interfaces with most existing 700c wheels thanks to its use of the tried-and-true HG freehub body design.

Alongside this suite of gravel-optimized gearing options 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. While the left lever of the 2x12 GRX group delivers Shimano's unrivaled smooth front 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.
