Electronic shifting for gravel: SRAM AXS vs. Shimano Di2. Is it worth the extra money?
Just a few years ago, electronic drivetrains were the domain of pro-tour road bikes—catalog gear more often seen on Instagram than on a dirt track. Today? Electronics in gravel bikes are no longer a whim; they're an increasingly common choice, especially on high-end bikes. But is it worth the extra cost? And which should you choose—Shimano Di2 or SRAM AXS?
Di2 vs AXS - operating philosophy
The differences between these two systems are apparent even at the level of thinking about the bike. Shimano Di2 (currently available in GRX RX825 and RX827 versions) prioritizes smoothness and predictability. The levers are wireless, but the derailleurs are wired to a central battery. It's a compromise between modernity and reliability—once you get it right, it runs like a Japanese watch.
SRAM AXS (in Rival, Force, Red, and its XPLR versions) is fully wireless: each derailleur and lever has its own battery, communication is wireless, and configuration is done via an app. It's modular, aesthetically pleasing, and... a little more freedom (or chaos, depending on your taste).

How does it work in real life?
In everyday driving, the biggest differences appear not on paper, but at hand:
- Shimano Di2 shifts almost silently—the click is more of an impulse than a physical movement. It's perfect for group rides, long climbs, or technical terrain. The new GRX Di2 also offers Synchronized Shift .
- SRAM AXS delivers a very distinct click—a solid, mechanical click with physical confirmation of the shift. The absence of cables in the frame means cleanliness and easier maintenance.
Service and batteries
Shimano has a single central battery that needs to be recharged every few weeks. SRAM has batteries in each unit, but they're replaceable, making it easier to keep a spare in your pannier.
With Di2, service sometimes requires E-Tube Project . With SRAM AXS, you can configure everything on your phone – quickly, intuitively, and without specialized tools.
Compatibility and expansion
Shimano GRX Di2 is more closed—you combine components within a single platform. SRAM AXS is like Lego: Rival can work with Force, and if you want a "mullet," you simply swap the rear derailleur for Eagle Transmission.
What about Poland? Does electronics make sense on our routes?
In theory: dust, mud, moisture – electronics don't like it. In practice: it works. Our tests and customer experience show one thing: properly adjusted electronics, regardless of brand, operate more stably than cables after the first rain.
Okay. And the price?
This isn't cheap—a Di2 or AXS setup adds at least several thousand to the bike's price. But it also means a more refined ride, fewer frustrations on the road, and more precision and comfort.
What to choose?
- Shimano Di2 GRX —for those who value smoothness, quietness, and technical excellence. Great for mixed riding, with panniers, and over long distances.
- SRAM AXS XPLR —for those who want crisp shifting, modularity, easy maintenance, and a crisp click. Perfect for harder gravel riding, bikepacking, and off-road riding.
