United in Gravel!
With a clear focus on the heart and soul of gravel biking, SHIMANO's electronic GRX series now gets a 12-speed update to deliver top performance!
Simplicity and reliability form the basis for the new 12-speed GRX range and allow you to enjoy special off-road adventures!

With the GRX Di2 RX825 12-speed rear derailleur as the master unit, the Japanese industry giant brings proven and reliable technologies to your gravel racer.
For example, the ingenious developers at SHIMANO have been inspired by the mountain bike sector and integrated the proven Shadow RD+ technology.
The forward and backward movement of the RD-RX825 Di2 rear derailleur is significantly slowed down by the adjustable friction damper.
This significantly reduces the risk of a chattering and jumping chain, incorrect shifting and noise development.
Silent, smooth, precise and reliable electronic shifting actions in rough terrain are therefore always guaranteed.
Whether it's on unpaved paths, on dusty gravel roads, during a bikepacking adventure with lots of luggage, during classic cyclocross or on the way to work (commuting).

- Wirelessly controlled, electronic 12-speed rear derailleur
- Di2 wireless chip with low interference probability, high processing speed and low power consumption
- Shadow RD+ technology (more damping in the cage)
- Direct mount compatible
- 4 fluorine-coated pivot bushings
- SD300 E-Tube Port: narrower cables for less weight and easier routing
- Bluetooth LE compatible: wirelessly customizable via E-Tube app for smartphone & tablet

- Status LED for system information and battery level display at the touch of a button
- Splashproof charging port for charging the central battery of the Di2 system
- Also suitable for wired setup

The first Shimano product was the bicycle freewheel, which also became the first product by Shimano to be exported in 1931.
Halfway through the 1950s Shimano expanded its range with a derailleur and a 3 speed hub.
In 1960 cold forging technology was introduced, quickly becoming a vital part of the production process and the main reason behind the premium quality of Shimano's bicycle parts.

Export figures grew exponentially. In 1965 and 1972 Shimano America and Shimano Europe were founded, and the first factories were opened in Singapore.
In 1973 the first complete Dura-Ace group came into being and Shimano Inc. became a publicly listed company.

Starting in the early 80s, the introduction of the mountain bike and the company’s leading role in its evolution led to rapid growth for Shimano Inc.
Then Shimano turned the road bike market upside down in 1984 with the introduction of indexed shifting (SIS), and again in 1990 with integrated braking and shifting (STI).
