After seven years, it’s finally here: Shimano has launched its new XTR groupset—and it’s now fully electric and wireless! I’ve had the chance to test the group myself, and I’m sharing here what’s new, how well it really performs, and what you should consider before buying.
The XTR has always been the top-of-the-line option in Shimano’s MTB range. It combines lightweight components with maximum performance and is designed for racing. With the new generation, Shimano takes the next step and finally brings Di2 wireless shifting to mountain bikes.

What’s New with the Shimano XTR 2025?
Finally, Wireless Electronic Shifting
The new XTR Di2 is now completely wireless—and you notice it immediately: no annoying cables, a tidy cockpit, a modern setup. The shifter has been upgraded and now operates exclusively with the thumb. That might be a bit of an adjustment for die-hard Shimano fans who liked using the index finger to shift, but the new design looks sleek and offers excellent tactile feedback. A single press shifts one gear, while holding the lever shifts multiple gears—just how I like it.
A New Derailleur with Integrated Battery
For me, the heart of the new XTR is the completely redesigned derailleur. Shimano has given it a wider linkage structure and a special guide-plate design to improve durability and robustness. You can really feel that on the trail—especially in rough terrain. What I really like is that the battery is now permanently integrated into the derailleur. That makes it more secure against impacts and vibrations and ensures it can’t just fall out.
The battery itself has 310 mAh—that’s 10 mAh more than SRAM’s AXS. A nice detail, even if it might not make a huge difference in real-world use.
Another smart touch: the pulley wheels are now better protected and fully enclosed, which helps prevent dirt from getting stuck—addressing a common weak spot on many derailleurs.
On the Trail: Fast and Precise—but Not Indestructible
In my test, the shifting was impressive across the board: fast, precise, and noticeably quicker than the competition. However, under full load, it feels a bit more delicate than SRAM’s derailleur—it clatters more when I’m really cranking hard. Shimano says that’s not a problem, but I’m curious how it will hold up in hardcore race conditions.
No UDH Compatibility
One important note: the new derailleur still mounts to a traditional derailleur hanger and doesn’t support SRAM’s UDH system. That means you’ll still need to adjust it manually, and installation is a bit more involved. Honestly, I’m okay with that, since it means the XTR remains backward-compatible. Every existing Shimano 12-speed bike can be upgraded with the new derailleur—a real plus for anyone who doesn’t want to buy a new frame.
Variants for Every Riding Style
Shimano offers four derailleur options:
- Long cage: for 10-51 12-speed cassettes—perfect for a wide gear range.
- Medium cage: for the new 9-45 12-speed cassette—great for Enduro or weight-conscious XC builds.
- E-bike variants: with 12-speed (10-51) for Hyperglide+ chains or 11-speed for Linkglide chains. These models draw power directly from the e-bike’s battery.
Battery Handling: Simple and Smart
The battery sits under a cover and is easily removed via a sliding mechanism. A small arrow shows the correct orientation on both the battery and the charger—charging is done via USB-C, which I find super convenient.
Crankset, Chainring & Cassette: Proven Tech with Refinements
Not much has changed on the crankset: it’s still built using Hollowtech II and is compatible with all SM-CRM96 chainrings. There’s a reinforced version with 160 mm arms for Enduro use, promising more durability and impact resistance.
The chainring still uses Direct Mount and Dynamic Chain Engagement. Shimano offers sizes from 28 to 38 teeth in two-tooth increments. The 28-tooth option was designed specifically for the 9-45 cassette and works seamlessly with the medium-cage derailleur.
The new 12-speed cassette sticks with the Micro-Spline standard but now features six shift ramps for smoother, faster shifting under load. As before, it’s made from steel, titanium, and aluminum—a perfect balance of weight and durability. Shimano recommends pairing it with the new derailleur for the best performance but stresses that it’s backward-compatible with existing 12-speed cassettes.
For racers, the new 9-45 cassette offers a 500% range—great for saving weight or improving ground clearance. One caveat: because of the tiny 9-tooth cog, you’ll need Shimano’s special TL-LR 021 tool for installation.
Customization via E-Tube App
As with other Di2 systems, all functions can be configured and updated through Shimano’s E-Tube app—a feature I’ve come to really appreciate over the years.
Brakes: Small Details, Big Impact
The 2-piston brake gets a new low-viscosity oil for better performance at the limits—though it’s not backward-compatible. Shimano is clearly focused on maximizing performance here.
The 4-piston brake sees the most exciting upgrade: the hose outlets have been moved towards the handlebar for better integration—great for a clean cockpit. The reach adjuster is now neatly integrated into the lever body and is easy to use. In my test, the brakes immediately impressed: powerful, precise, and predictable. The redesigned pad mounts reduce noise and rattle, while the new oil promises more consistent power delivery.
New Wheels & Hubs: Light, Strong, Durable
Shimano’s new wheels use the latest low-maintenance, easy-service cartridge bearings in Boost hubs (28 or 32 holes). The XC wheelset weighs in at under 1300 g—which is impressive for a hooked rim. Shimano’s reputation for durability and quality shines through. I’m curious to see how it stacks up against established options like the DT Swiss XRC 1200.
The Enduro wheelset features a 30 mm wide hookless carbon rim and stainless steel J-bend spokes. Shimano claims it’s their toughest wheelset yet—built for the hardest Enduro races. That sounds like a solid choice for riders who prioritize durability above all else.
Conclusion: Shimano XTR M9200 – A Solid Step Forward for Racers and Trail Riders
The new wheels and hubs are sure to perform exceptionally—especially the XC wheelset, which promises to be a real weapon. Of course, the price-to-performance ratio will be an important factor for many racers, and I’m looking forward to seeing how Shimano’s offering compares to long-established competitors like the DT Swiss XRC 1200.
The brakes impressed me right from the first test. The new oil brings even more consistency and makes an already excellent brake even better. The 4-piston brake’s design might be a matter of taste, but I’m a fan of the clean cable integration.
The drivetrain itself delivers what Shimano has always stood for: fast, precise, and reliable shifting performance. The integrated battery and fully enclosed pulley wheels are thoughtful additions that enhance durability and functionality.
For anyone currently riding a mechanical setup, the new system is a noticeable upgrade—and retrofitting is easy. And if you’re getting a new bike equipped with the XTR, you’ll definitely be happy with it. Shimano remains a benchmark in terms of quality and performance—once again setting new standards for racers and trail enthusiasts alike.
