Smooth Shifting Adventure: Shimano GRX RX810 2x Derailleur Review
The smooth-shifting of this derailleur is not just all talk. The features stand tall.
The Evolution of GRX
The Shimano GRX RX810 rear derailleur is a result of meticulous design and engineering, drawing inspiration from Shimano’s mountain bike and road groupsets.
It inherits the clutch mechanism from the Ultegra RX derailleur, which effectively reduces chain slap and dropped chains, ensuring a quieter and more secure ride on any terrain.
By integrating a chain stabilizer mechanism, Shimano has enhanced shifting security and precision, making it ideal for mixed-terrain adventures.
Unparalleled Shifting Performance
One of the standout features of the GRX RX810 derailleur is its silent and uninterrupted rear shifting, even on rough and challenging terrain.
The adjustable chain stabilizer effectively prevents chain slapping and drops, allowing for a smoother and more reliable shifting experience.
And this is particularly crucial when navigating unpredictable off-road conditions, providing you with the confidence to conquer any trail.
The Secret to Smooth Shifting
The GRX RX810 derailleur incorporates Shimano’s Shadow RD+ technology, which further enhances the shifting performance. This technology, inspired by mountain bike derailleurs, ensures crisp and precise shifting on both mixed surfaces and paved roads.
And on top of that, the Shadow RD+ feature also allows you to toggle the clutch on and off, enabling you to adapt to different terrains effortlessly.
When engaged, the clutch increases spring force, minimizing chain slap and maintaining chain tension, resulting in a stable and efficient drivetrain.
Gravel-Tuned for Optimal Performance
As the name suggests, the Shimano GRX series is specifically designed for gravel riding, offering riders the perfect balance between road and off-road capabilities.
However, the GRX RX810 derailleur is equipped with a gravel-tuned clutch tension, ensuring consistent chain stability even on the roughest terrains.
This feature allows you to confidently tackle challenging gravel roads and singletrack trails without worrying about dropped chains or excessive chain noise.
Versatility for 2x Setups
Traditionally, Shimano has primarily focused on 2x setups for road groupsets. However, with the GRX RX810 derailleur, they have expanded their offerings to include both 1x and 2x configurations.
And this versatility gives riders the freedom to choose the gear ratio that best suits their riding style and terrain.
Plus, the short-cage model of the GRX RX810 derailleur is optimized for an 11-34t cassette, providing a wide range of gear ratios and smoother transitions between gears compared to a 1x setup.
Enhanced Durability and Weight Optimization
Shimano’s commitment to quality and durability is evident in the GRX RX810 derailleur. As part of the Ultegra groupset, it benefits from the same high-quality materials and finishes that Shimano is known for.
Moreover, the derailleur’s construction strikes the perfect balance between lightweight design and robustness, ensuring it can withstand the rigors of intense rides and rough terrains.
Whether you’re racing or embarking on a bikepacking adventure, the GRX RX810 derailleur is built to withstand the demands of your journey.

Installing the GRX RX810 derailleur onto your bike is a seamless process. It is designed to be compatible with current road DUAL CONTROL LEVER systems, ensuring hassle-free integration into your existing setup.
The derailleur’s maximum front difference of 17T allows for smooth and efficient shifting between chainrings, while the 11T/34T maximum low sprocket ensures a wide range of gearing options for tackling steep climbs and fast descents.
With a total capacity of 40T, the GRX RX810 derailleur caters to a variety of riding styles and preferences.
User-Friendly Adjustments for Optimal Performance
