Built for gravel, adventure and mixed-terrain riding, this complete Shimano GRX 2x12-speed mechanical groupset gives you a wide-range gravel drivetrain, crisp cable-actuated shifting and powerful hydraulic disc brakes in one kit. A 48-31T double crankset paired with an 11-36T cassette gives you a huge spread of gears with small, even steps between them, so you can hold a comfortable cadence whether you're cruising flat gravel roads, rolling over endless dirt-road hills or grinding up a big backcountry climb. Simple, reliable and easy to maintain, it's everything you need for a complete build or a full drivetrain upgrade.
KEY FEATURES
- 12-Speed Gravel Drivetrain: A 2x12-speed setup gives you a wide gear range with tight, even gear steps, so you're never stuck between gears on long climbs or fast rolling terrain.
- Gravel-Specific STI Levers: The ST-RX820 dual control levers have a gravel-optimised shape that sits naturally on flared handlebars. Raised hoods with a ribbed texture and anti-slip brake levers give you a secure grip when the going gets rough.
- Hydraulic Disc Brakes: BR-RX820 flat mount calipers give strong, consistent stopping power with fine control on loose descents and rough gravel.
- SHADOW RD+ Rear Derailleur: The RD-RX820 rear derailleur has a SHADOW RD+ chain stabiliser that keeps the chain stable and quiet over rough surfaces, helping to stop chain slap and dropped chains. An on/off switch makes rear wheel removal easy. It handles cassettes up to 36T.
- Tyre-Clearing Front Derailleur: The FD-RX820 braze-on front derailleur is designed for gravel bikes, with plenty of clearance for the wide tyres modern gravel frames run.
- 48-31T GRX Crankset: The FC-RX820-2 2x12-speed crankset uses gravel-optimised gearing with a 17T front range, keeping gear steps tight for cadence control on rough surfaces. It comes in a 172.5mm crank length.
- Wide Range Cassette: The CS-HG710 11-36T 12-speed cassette gives a 327% gear range, with gear steps tuned for pedalling efficiency. The first eight cogs are close together for smooth riding, and the four biggest cogs give you climbing gears without abrupt jumps.
- XT 12-Speed Chain: The CN-M8100 Deore XT chain gives smooth, quiet, efficient running and strong chain retention. It comes in 126 links with a quick link for easy fitting.
- Ice Tech Rotor: The RT-CL800 160mm Centre Lock rotor uses Shimano's Ice Technologies construction for great heat management and consistent braking, with quick and secure Centre Lock fitting.
