Electrifying Shimano's 12-speed gravel component family, the new 2x12-speed GRX RX825 Di2 Groupset combines Shimano's unrivaled electronic shifting with optimized gearing options for riding, racing, and all-day adventures.
The new suite of electronic Di2 parts features dual control levers refined for comfort and control, a SHIMANO SHADOW RD+ equipped rear derailleur for better chain management, and a gravel-optimized front derailleur for precise shifting.
Like its 12-speed Di2 siblings, the new GRX Di2 system is wired where it makes sense, featuring a central, multi-port battery that supplies stable, long-lasting power to both front and rear derailleurs. Smaller diameter wires connect directly from the battery to each derailleur, eliminating the need for junctions and streamlining the build process. The central internal battery also simplifies charging and remains secure over the roughest roads, trails, or whatever less traveled path a rider may choose.
Shimano's 12-speed GRX Di2 features a wireless gravel-specific cockpit where raised hoods with ribbed surface texture and anti-slip brake levers provide ultimate hand security no matter how spicy the ride gets. That secure hand position is enhanced with the location of the third Di2 button on the inside of the hood. Whether used as another shift location or for scrolling through screens on a cycle computer, this third button is another way to fully experience Shimano's electronic Di2 system.
The RX825 rear derailleur features Shimano's pioneering Shadow RD+ technology. With its convenient on/off switch, Shadow RD+ makes removing the rear wheel easy when turned off. When on, the drivetrain is under additional tension that makes for a quieter ride and more precise shifting.
Like the very first GRX groups, the RX825 FD system employs a wider, +2.5mm chainline for improved tire clearance. This is especially helpful with the trend towards wider tires and events where mud is expected.
Using Shimano's E-TUBE PROJECT Cyclist application, riders can choose between different gear shift intervals for multi-shift, customize shift button assignment (what buttons perform which functions), program different automatic shift modes like Synchronized and Semi-Synchronized shifts, and fine-tune shifting.
Shimano's new FRONT SHIFT NEXT functionality can now utilize the E-TUBE PROJECT Cyclist app to program any 12-speed Di2 button to shift the front derailleur to whichever chainring you are not currently using and then toggle back and forth using the same button. The result is simpler, more intuitive shifting for less-experienced riders and quicker decision-making for veteran riders in the heat of competition.
