What Gravel Drivetrain Will Be Best in 2025? Shimano, SRAM, and Campagnolo Groupset Overview
Gravel in 2025 is no longer an experiment, but a fully-fledged branch of the cycling market—with dedicated drivetrains, technology, and design philosophy. In this article, we examine what's new from Shimano, SRAM, and Campagnolo, who their drivetrains are for, and what we can expect next.
Need an introduction? What is a gravel bike?
Shimano GRX – the precision of evolution
Shimano surprised us with the seamless transition from mechanical to wireless electronics with the GRX 1x12 Di2 (RX827). Based on MTB technology, this completely cable-free system offers smooth gear shifting, an impressive battery range (up to 1000 km), and smooth shifting even under load. All in a design ready for the realities of gravel riding.
The 2x12 RX825 Di2 version is particularly noteworthy for those seeking a wider range and more controlled shifting. Synchronized Shift technology, previously found on road and mountain bikes, works incredibly smoothly here. It allows for automatic rear sprocket shifting when the front chainrings are switched, making it easier to maintain pedaling rhythm and creating a sense of "continuous" gearing.
The RX820, the mechanical option, is an evolution of the well-known and beloved GRX RX810. It offers a wider range, improved ergonomics, support for cassettes up to 51 teeth, and very reliable performance in the harshest conditions. Shimano doesn't try to be flashy—instead, it delivers a predictable, durable, and customizable system. RX600 and RX400 (11- and 10-speed) are still available, making GRX one of the most flexible systems on the market.

SRAM XPLR and Rival AXS – Wireless Gravel with Character
SRAM has gone all-in on a single card: a wireless, 13-speed gravel drivetrain. The Force XPLR AXS is currently one of the most popular drivetrains for modern gravel bikes—by both amateurs and semi-pros. The shifters are ergonomic, the button layout intuitive, and gear changes quick and quiet. The Full-Mount system eliminates the need for a traditional derailleur hanger, increasing the stiffness and durability of the entire system.
Importantly, SRAM has maintained its single-speed philosophy throughout the XPLR line. 10-46T cassettes offer a wide range, and thanks to narrow-wide chainrings, the chain stays on the chainring even on challenging terrain. Force XPLR AXS works seamlessly with dropper post mounts, boasts a low q-factor, and is fully supported by the AXS ecosystem.
The Rival XPLR AXS 1x13, while cheaper, isn't a compromise. It's based on the same technologies as the Force and Red, offers the same wireless system, and is also perfect for everyday riding, touring, and bikepacking. It's one of the best mid-entry groupsets currently available on the market if you want simplicity and digital control without unnecessary cables.
Campagnolo Ekar GT and Super Record Wireless – Italian style and advanced technology
The Ekar GT is a lighter and more durable version of the classic Ekar. This mechanical 13-speed groupset is designed specifically for gravel riding. Gear shifting is stiff, precise, and lag-free—a hallmark of Campagnolo's "soft power," meaning smooth operation combined with mechanical responsiveness. The ergonomics of the shifters have been improved, and the entire system operates smoothly even in sand, mud, and cold.
The biggest news from Campagnolo, however, is the Super Record Wireless 2x13—the brand's first-ever wireless drivetrain, which combines technology and tradition. The return of the thumb shifter in a new form, two chainrings, thirteen rear speeds, and ultra-fast shifting response—all combine to make this drivetrain one of the most sophisticated on the market. Although primarily aimed at road riding for now, a test version of the 2x13 with a clutch-type chainring was seen on the Unbound Gravel, suggesting Campagnolo has ambitions to expand this system to the off-road segment as well.
1× or 2×? Reflections for 2025
In 2025, 1× drivetrains are not only a technical choice, but also a stylistic one. Fewer cables, a cleaner cockpit, a reduced risk of failure, and easier assembly. Thanks to new cassettes: 10-46T (SRAM), 10-51T (Shimano), and 9-45T (TRP), the available gear range covers the needs of most riders—from bikepacking to fast, sporty rides.
2x is still the gold standard for those who want complete control over cadence. Ideal for mixed riding: road, climbs, and gravel. New groupsets like the GRX Di2 RX825 and Super Record Wireless prove that you can combine advanced electronics with a double chainring without compromising ergonomics or smooth operation. If precise gear matching to the terrain is your priority, a 2x system will be hard to beat.

Electronics in gravel – functionality over fashion
Electronic drivetrains today are all about convenience and precision. Shimano GRX Di2 (RX825 and RX827) and SRAM AXS (Rival and Force XPLR) eliminate the need for cable adjustments, offer full customization, and allow for integration with other components (e.g., dropper posts, computers, mobile apps).
SRAM stands out for its complete wireless capability—including between the levers and derailleurs. Shimano, on the other hand, employs a semi-wireless system: the shifters are wireless, but the rear and front derailleurs are wired to a central battery. Both philosophies have their advantages. SRAM prioritizes complete installation freedom and aesthetics, while Shimano offers greater reliability in extreme conditions and longer battery life.

What to choose in 2025? Which group for whom?
- For beginner and budget bikes: Shimano GRX RX400/RX600 or SRAM Apex/Rival – simplicity, reliability and good parts availability.
- For bikepackers and tourers: Shimano GRX RX820 (1×12) or SRAM Rival XPLR AXS – wide range, durability and minimal maintenance.
- For those who value modern technology and aesthetics: SRAM Force XPLR AXS or GRX RX825 Di2 – digital precision and full integration.
- For individualists and aesthetes: Campagnolo Ekar GT (mechanical precision) or Super Record Wireless (new 2×13 with a classic twist).

Summary
2025 brings more diversity than ever before. Shimano is developing GRX in both directions—for both traditionalists and electronic fans, offering support for 1x12 and 2x12 with interesting features like Synchronized Shift. SRAM responds with a comprehensive AXS offering, featuring a new Full-Mount system and thirteen speeds in a completely wireless format. Campagnolo is back on the offensive: Ekar GT is a mechanical with soul, and Super Record Wireless is a sophisticated new feature that may soon be available in gravel versions as well.
What's next? Campagnolo is testing 2x13 gravel bikes with clutch derailleurs, which could officially debut this year. SRAM is developing its AXS platform and may surprise with a new, even more versatile groupset. Shimano, in line with its strategy, may also bring Di2 technology to more affordable segments. The market isn't slowing down, and gravel drivetrains are growing in strength—which is a good thing, because we have plenty to choose from.
