Shimano GRX ST-RX825 Di2 Shift/Brake Lever

Gravel is the great equalizer. No matter who you are, where you come from or where you want to go. Gravel celebrates individuality. It welds together in a shared passion. It lays the foundation for friendships and creates memories for the ages. Whether you ride one kilometer or a hundred. Whether with professional equipment or without. With a 10-speed, 11-speed or 12-speed gear system. Whether on paved roads, forest roads, back roads – or no roads at all. It does not matter why you are out there, all that matters is that you are.

More control and integration on the next Gravel adventure – that is the promise of the electronic components of the RX825 series which expand Shimano's GRX family with the proven and at the same time improved Di2 functionality. The wireless cockpit is defined by the STI levers, which are designed for use on mixed terrain and combine sophisticated ergonomics with fast, wireless shifting performance.

A special feature is the third button on the inside of the hoods, which can be used to activate the front derailleur via the FRONT SHIFT NEXT function to easily switch the chain to the chainring that is not in use. As all function buttons on the ST-RX825 shift/brake levers can be freely configured using the E-TUBE Project Cyclist app, the shifter can also be used in other ways, e. g. to switch between the individual screens of a compatible bike computer. If this is still not enough customization for you, you can combine your Dual Control lever with one of the three options of the SW-RS801 satellite switch (sold separately).

The design of the GRX Di2 brake/shift levers is based on their mechanical counterpart, which adapts to modern Gravel handlebars with plenty of Flare. The slightly rounded shape not only ensures a seamless transition into the flared handlebars, but also increases the grip surface in combination with the raised horns, which reduces the risk of pressure points. In addition to the ribbed surface of the rubber grips, the non-slip coating on the brake lever blade provides the necessary grip. Speaking of brakes: in terms of deceleration, the proven SERVO WAVE technology ensures particularly good modulation. In addition, the brake lever can be adjusted in reach and free stroke.
