Shimano GRX RX820 1x12S Disc groupset
Gravel is all about simplicity, inclusiveness and adventure. Everyone from beginners to Gravel veterans can count on Shimano GRX, the first Gravel-specific groupset, for smooth shifting, reliable braking and unrivalled comfort. The new RX820 series offers top-level performance at an incredible price, with an ergonomic design and a drivetrain specifically for Gravel and all off-road adventures. The 12-speed GRX drivetrain systems offer precise and reliable mechanical shifting. This all-road-oriented 1x12S is designed to allow you to continue riding comfortably on your multi-day adventures, over the toughest climbs and in the most unpredictable conditions.
Greater safety on any road - Gravel-optimised ergonomics
The GRX brake levers have a robust non-slip coating to ensure greater grip and control even in heavy rain, splashes and mud. The non-slip surface of the GRX hand guards guarantees constant control, even on the roughest descents. The non-slip surface of the GRX brake levers guarantees Shimano's legendary stopping power at all times, even in the presence of water or mud. The new shape of the GRX RX820 handguard distributes pressure over a larger surface area of the hand, maximising comfort on long rides.
Slowing down has never been so pleasant - race-ready braking system
The GRX BR-RX820 disc brake calliper offers new levels of control, with improved modulation and a more immediate braking attack point. And despite its smaller design, the system is quieter than ever and maintenance is easier. (pads are included).
More chain stability and quieter and more stable gear changes for Gravel
Thanks to the integrated chain stabiliser, the SHIMANO GRX rear derailleur offers quieter gear changes and safer chain handling on uneven terrain. The RD-RX822-SGS rear derailleur is compatible with SHIMANO MTB 10-51D 12v cassettes, so you'll never run out of gears even on the steepest climbs of dirt roads or high mountain singletrack. And the chain tensioner has an ON/OFF switch for easy wheel removal.
The wide range of options offers ideal gear ratios for Gravel and a wide range of cyclists
The SHIMANO FC-RX820-1 crank offers the perfect balance of light weight, optimised efficiency and a range of ratio options to meet the segmented demands of mixed-terrain riding. By combining a 10-45D or 10-51D cassette with a 40D or 42D sprocket, you can choose closer, more progressive ratios or the widest range. The FC-RX820-1 is available with 170, 172.5 and 175mm crank lengths, providing a further degree of customisation.
