Let’s have a look at the features that make this groupset a great choice for gravel enthusiast.

Design and Comfort

One of the standout features of the GRX RX810 1x Mechanical Groupset is its well-thought-out design that prioritizes comfort and control.

The brake lever’s pivot point has been strategically moved upwards by 18mm, resulting in a more pronounced hood hump. 

This design adjustment enhances the security and stability when riding over rough and uneven surfaces.

Additionally, the curved shape of the levers and the textured finish of both the hood and levers offer excellent grip for riders to maintain confidence and control in challenging conditions.

Shifting Performance

Whether you need to pop up a single gear or quickly dump a few at a time, this groupset delivers swift and accurate shifting, ensuring a seamless riding experience.

Shifting Performance

The larger pulleys and longer cage of the RX810 efficiently handle the extended chain length, maintaining chain tension and reducing the risk of chain drops.

Both upshifts and downshifts with the GRX RX810 are instant and smooth, enabling quick gear changes with ease.

Whether popping up a single gear or shifting multiple gears, the groupset responds promptly, ensuring efficient power transfer and maintaining cadence.

Enhanced Ergonomics and Grip

The brake lever’s upward pivot point, raised by 18mm, creates a more pronounced hood hump, offering a secure grip on rough terrains.

The curved levers and textured finish further enhance finger hooking and grip, ensuring confident control in challenging conditions.

Optimized Chain Management

GRX RX810 features larger pulleys and a longer cage to accommodate the extra chain length.

This design ensures smooth chain movement and reduces the risk of chain drops or derailments during demanding off-road rides.

Superior Braking and Modulation

One of the best thing about this groupset is the excellent lever feel and modulation. As a result, you get precise control over braking. Even in the hoods, it’s possible to apply three-finger braking comfortably when needed.

This reliable braking performance instills confidence during descents and technical maneuvers.

Versatile Crank Options

The GRX RX810 crank comes in both 1x and 2x options, catering to different rider preferences. With offset chainrings, the crankset provides increased clearance from the frame and tires, ensuring compatibility with various gravel setups.

Optimized Front Derailleur Design

The front derailleurs of the GRX RX810 are slightly offset to match the cranks and sit further outward. This design assists in smoother front chainring transitions, particularly when encountering larger gear jumps.

Compatible and Adaptable

The Shimano GRX Groupset is designed to be compatible with a wide range of Shimano components from both the MTB and Road Groupsets.

This compatibility allows riders to personalize their setups and integrate other Shimano components seamlessly.

Unique Selling Points
