The result is the Shimano GRX components, which represent the first series specially developed for riding on rough roads and through gravel. Shimano GRX sets itself apart from the rest of the component world with its gravel-specific ergonomics, optimized gearing options, rugged reliability, and a quiet and stable drivetrain.\u003c\/em\u003e\u003c\/p\u003e\n\u003ciframe allowfullscreen=\"\" frameborder=\"0\" src=\"https:\/\/www.youtube-nocookie.com\/embed\/s5tRIile7L4?rel=0\u0026amp;showinfo=0\u0026amp;enablejsapi=1\u0026amp;origin=https%3A%2F%2Fwww.bike24.com\" loading=\"lazy\" title=\"Video: Shimano Rear Derailleur 11-speed GRX RD-RX812 40-42T max\"\u003e\u003c\/iframe\u003e\n\u003ch3\u003eShimano GRX RD-RX810-GS \/ RD-RX812-GS Shadow RD+ rear derailleur\u003c\/h3\u003e\n\u003cp\u003eThe mechanical Shimano GRX rear derailleurs, RD-RX810 and RD-RX812, are characterized by quiet, smooth, precise, and reliable shifting even in the most demanding terrain. This is mainly due to the Shadow RD+ chain stabilization system, which prevents the chain from slapping and dropping and also reduces unnecessary movement of the derailleur cage, thus ensuring uninterrupted shifting performance. This is why an ON\/OFF switch can be found next to the upper pulley, much like Shimano’s mountain bike derailleurs. When activated, the rear derailleur pivot takes a firm hold to reduce excessive movement, noise, and general \"chain chatter\".\u003c\/p\u003e\n\u003cp\u003eThe RD-RX810 rear derailleur accommodates cassettes with 11-30 teeth up to cassettes with 11-34 teeth.
