Specialized says the Diverge 4 is the “ultimate getaway vehicle,” and the Expert AXS build might be the lineup’s sweet spot. Sitting below the Pro and Pro-LTD halo models, it delivers a FACT 9r carbon frame, Future Shock 3.2, SWAT 4.0 storage, and Roval carbon wheels, all tied together with SRAM’s Rival AXS XPLR drivetrain. All that for $4,600 less than the top tier — and let me tell you, it’s a ripper on the chunky gravel.

Build Breakdown: All Killer No Filler

The Diverge 4 Expert AXS comes spec’d smartly with all the gear you would want in a bike of this caliber, but nothing extra “just for show”. It starts with the SRAM Rival AXS XPLR groupset. It’s a great-looking groupset and sets off the gunmetal matte frame nicely. The crankset is one of my favorite features, and it looks great on the new Diverge4.

However, looks aren’t everything, so I must mention that it shifts crisply, the brakes are leagues above the previous version, and with the wide 10-46T cassette, it feels perfectly at home on gravel epics when you run out of legs. The Roval Terra C carbon wheels add stiffness and drop some weight, and the DT-Swiss 370 hubs let you know the wheels will be around for a while. They come wrapped in 45mm Pathfinder Pro tubeless tires (a favorite of mine) that feel fast on pavement but confident when the road dissolves into dirt.

The build strikes a nice balance, light enough for racing, yet solid enough for adventure. The finishing kit is equally well thought out, featuring SWAT storage (a bag is included) that accommodates ride essentials and a cockpit designed for lots of different hand positions.

The Good, The Great, and The Slightly Bouncy

The standout tech of the new Diverge is Future Shock 3.2. Sitting above the headtube, it provides 20mm of travel that absorbs chatter before it ever reaches your hands. On roots, broken pavement, and chunky doubletrack, it’s nothing short of brilliant. It’s downright fun when you get into the singletrack, but you can get into trouble quickly with the 45mm tires if you get too gnarly. In a nutshell, the system smooths out high-frequency vibration, takes the edge off square hits, and helps keep traction when the road gets loose.

The Specialized “suspend the rider” approach really works; your legs and arms stay fresher on long days, and it’s hard not to notice the reduced fatigue after three or four hours of gravel pounding, especially on the shoulders (mine at least). Descending fast on loose terrain, the Diverge feels planted and confident, letting you focus on line choice instead of bracing for every bump. The travel allows the front end to absorb the bumps and not skid out or bounce on washboards and wild terrain.

Adjustable Confidence

That said, there’s a trade-off. On steep, punchy, slightly rolling climbs, the Future Shock can feel a little “bouncy.” It’s not dramatic, but when you’re out of the saddle and really stomping on the pedals, you notice the front end moving just enough to remind you there’s a suspension system up there. Thankfully, it’s not pogo-stick mayhem (the damping keeps things composed), but you do lose a touch of that razor-sharp, road-bike feel. Specialized includes different tuning springs to fine-tune the system for rider weight and terrain, and I’ll admit I barely scratched the surface of utilizing them. With more time, I’m confident I could smooth out the sensation to match my style better. Maybe I’m just hypersensitive from years of cursing forks that would bob on nasty climbs, but for me, it only shows up when you’re standing, leaning forward, and really driving over the bars.

On the Road | Off the Map

On gravel, the Diverge 4 Expert AXS is in its element. The Future Shock and Pathfinder Pro combo keeps speed high while muting the bigger bumps of adventure. The geometry feels like a mountain bike (sorta). The slacker head tube, longer reach, lower BB—gives it the confidence of a modern trail bike but without dulling the quick handling you want in a race. It feels “in” the bike, not perched on top, which translates to descending confidence when the surface turns sketchy.

On pavement, the Diverge feels fast, but you’re reminded it’s a gravel-first machine. The 45mm tires hum slightly, and the subtle front-end movement on challenging climbs is noticeable. Swap to a 38 mm slick, and the bike transforms into a much sharper road weapon. That versatility is what makes the Diverge compelling; you can tune it to your ride style, terrain, and goals.

Plus, it has mounts galore, and not just the 3-pack ones, but fender mounts. However, they don’t stick out like a sore thumb or need a “hidden bolt that might or might not have come with your frame” like some other bikes I’ve had.

Room For Snacks & More

The new SWAT storage is huge. Yes – the downtube is slightly bigger on the updated Diverge 4, and they filled that space with… nothing. Well, more specifically, a nice waterproof-ish, zippered bag of nothing with a very easy-to-grab tether.

You can fit a lot of flat gear, a rain jacket, and more in the new SWAT storage. You can also move your water bottle mounting bolts slightly. All the hoses are tucked nicely inside, so there is zero worry about snagging them.

Who’s It For?

The Diverge 4 Expert AXS is for the gravel racer who doesn’t want to sacrifice adventure capability. It’s light, stiff, and fast enough to sit in the front group at a gravel race, but the Future Shock, big clearance, and SWAT storage make it a tool for long rides, bikepacking, or all-day mixed-surface exploring.

Review Specialized Diverge 4 made in

At $6,000, it’s not cheap, but compared to the Pro and LTD builds, it delivers most of the tech and ride quality without the flagship price tag. If you really wanted to make this bike a race-day machine, I would take the $4,000 you didn’t spend on the LTD version and invest in a high-end set of wheels – though, realistically the included Roval Terra C carbon wheels are perfectly suited to the needs of this bike, and you’re probably better off saving that $4k for race entries and travel fees and just go ride your bike.

Lasting Impressions

Though we’ve had little time on the Diverge 4 Expert AXS, the message is clear. This bike is for those looking to enjoy time on gravel. Whether that’s racing, adventuring, or underbiking, the Diverge excels.

It’s gonna take some more time on the Future Shock to get it completely dialed, but it’s way more of an asset than a drawback. Specialized really nails the balance between speed and comfort on this one.

Big fan of the Diverge, I’ve owned every model since the original, but wow, what an underwhelming bike launch. 3 mm increase in tire clearance, new SWAT, and UDH? That’s it? Future shock 3.0 is over 2 years old. Specialized felt a need to embargo this bike? It’s more of a running update. I get, if it’s not broke, but why the long tease Specialized?

from what I’ve seen elsewhere…the 3mm additional clearance (on 50mm tires) includes 8mm clearance on both sides of the tire (16mm total). The Bicycles Station fit upwards of 56-57mm WAM tires with “adequate” dry weather clearance….so put your 2.2’s on there and enjoy. I thought the same thing though on initial release with only 3mm more clearance.

What? Cannondale old school DD50 with lockout is better?

The only driver for this update must be to be able to offer builds with the new SRAM drivetrains. My current Diverge already accepts 52mm tires in dry conditions. My Futureshock seized up and I replaced it with a stubby which lowers the stack heigh and makes it a bit more racy. I would recommend that for those experience the same.

At this price point, the future shock should be the adjustable version, but hey, look how much stuff you can cram into the downtube storage.

$6k for third tier SRAM, none adjustable futureshock, and alloy bars. Insane.

That hover bar just looks dumb and is a nightmare for accessory mounting. Just use a level bar and a 0-degree stem and the hand position will end up almost identical.
