Features shimano grx8201 1x12v 42t 172.5 10/51
Shimano GRX, the industry's first gravel-specific groupset, for smooth shifting, reliable braking and exceptional comfort.
The new RX820 series offers premium performance at an incredible value, with ergonomic designs and gravel-focused gears for all those off-road adventures. Its three GRX 12-speed transmissions offer precise and reliable mechanical shifting with different gear ranges to cover the entire spectrum of cyclists and routes.With its integrated chain stabilizer, the SHIMANO GRX derailleur provides quieter shifting and safer chain management on rough terrain. It's compatible with SHIMANO 10-51T 12-speed MTB cassettes, meaning you'll never be out of gears, even on the steepest climbs on mountain roads or high-mountain singletrack. And the chain tensioner has an ON/OFF switch for easy wheel removal.
The SHIMANO FC-RX820-1 crank balances weight savings, optimized efficiency and a series of shifting options that meet the segmented demands of mixed-terrain driving. By pairing a 10-45T or 10-51T cassette with a 40T or 42T chainring, riders can choose shorter gear steps or the ultimate range. The FC-RX820-1 is available in 170, 172.5 and 175mm crank arm lengths, providing an additional level of customization.
GRX brake levers feature a robust non-slip coating to ensure better grip and control, even when faced with heavy downpours, splashes and muddy conditions. With a rounded profile, the new GRX RX820 ramp shape distributes pressure over a greater surface area of the hand, ensuring greater comfort for longer. The GRX BR-R820 disc brake caliper brings a new level of control to the world of gravel cycling with improved modulation and a faster initial braking point. And despite its smaller build, the system is quieter than ever and easier to maintain.
