Every air-vs-coil argument on a DH bike eventually lands on the same sentence: “air shocks just don’t feel like coil on repeated hits.” EXT, the Italian boutique suspension brand that’s spent years building hardware for World Cup DH teams like Intense Factory Racing, just shipped a shock aimed directly at killing that sentence. The Aria V2 and Aria V2 DH launched September 23, 2026, and the DH variant drops EXT’s trail-oriented lockout lever entirely in favor of a gravity-specific bottom-out circuit. The pitch: tunability that doesn’t require plastic volume-reducer tokens, on a shock built for the one discipline that’s stayed loyal to coil the longest.

That’s a bold thing to promise. DH racing is the last corner of mountain biking where coil still wins arguments by default — the small-bump sensitivity and consistent mid-stroke support of a metal spring are why our own rear shock guide flagged the EXT Storia as the most refined bottom-out adjustment we tested, at a price that excluded 90% of riders. The Aria V2 DH is EXT’s attempt to get some of that feel into an air shock, and at $1,200 / €1,100, it’s priced to actually compete rather than sit in a boutique-only tier.

Quick Take

What it is	EXT’s redesigned flagship air shock, launched in trail (Aria V2) and gravity-specific (Aria V2 DH) variants
Announced	September 23, 2026
Price	$1,200 USD / €1,100 — same for both versions
Spring tech	AS3 dual positive-chamber air spring — independent support and progression tuning, no volume-reducer tokens
Aria V2 DH difference	No LOK 2.0 lockout lever; DH-specific Hydraulic Bottom-Out Control claiming ~20% more end-stroke force than standard Aria V2
Weight	622g (210x55mm, standard Aria V2) / 667g (250x75mm, Aria V2 DH), per manufacturer spec

Best for	DH and heavy enduro riders who’ve wanted coil-like bottom-out control without the weight and spring-swap hassle
Skip if	You’re trail riding under 160mm — the standard Aria V2 or a simpler shock makes more sense, and nobody’s ridden this one yet

The Complaint EXT Is Actually Answering

Volume-reducer tokens are the industry’s long-running workaround for one air shock problem: you want a supportive, bottomless feel late in the travel, but stacking plastic spacers into the air can to get there often creates a harsh ramp instead of a smooth one. Fox, RockShox, and basically everyone else sells tokens as the tuning tool. EXT’s pitch with the AS3 spring is that tokens are the wrong tool entirely — that the real fix is giving riders two independently adjustable air chambers instead of one chamber plus spacers.

It’s the same instinct that’s been showing up elsewhere in the industry lately. Specialized’s GENIE spring — now built by both Fox and RockShox — splits travel into a supple first 70% and a progressive final 30% using two connected chambers that work as one spring, then close off. EXT’s approach is a different mechanism (fully independent chambers you tune separately with a shock pump, rather than one spring that automatically changes character), but the goal is identical: more control over the spring curve without relying on spacers you have to pull the shock apart to add or remove.

What Is EXT’s AS3 Dual-Chamber Air Spring?

AS3 is EXT’s dual positive-chamber air spring design. A ”+” chamber controls dynamic sag and roughly the first 60% of travel; a separate ”++” chamber manages progression through the mid-to-late stroke, adjusted independently with a shock pump. A large, self-equalizing negative chamber handles initial-stroke comfort. The result, per EXT, is token-free tuning of both support and ramp-up.

That’s a meaningfully different approach than most trail/enduro air shocks on the market, where a single positive chamber does all the work and tokens are the only way to change how hard the shock ramps up late in the stroke. Two separately pressurized chambers means a rider can add support without automatically adding progression, or the reverse — something our suspension setup guide has flagged as the exact tradeoff token-based tuning struggles to separate.

What’s Different About the Aria V2 DH?

The Aria V2 and Aria V2 DH share the AS3 spring architecture, the monotube body, and the 14mm chromoly shaft. Past that, EXT built the DH version around a different job entirely. According to Bikerumor’s coverage and bike198’s breakdown of the launch, four things separate the DH variant from its trail sibling:

1. No LOK 2.0 lockout lever. The trail Aria V2 keeps EXT’s climb-friendly lockout. The DH version drops it — nobody’s locking out a downhill bike’s rear shock mid-run, and removing the hardware simplifies the shock body for gravity-specific frames.
2. A DH-specific Hydraulic Bottom-Out Control circuit. EXT claims it generates roughly 20% more force at the end of the stroke than the standard Aria V2’s HBC, aimed at the big compressions and flat landings a DH bike sees that a trail bike mostly doesn’t.
3. A longer-stroke tune. The DH variant is built around the longer end of EXT’s size range rather than the shorter trail-oriented strokes, which tracks with how most gravity bikes are speced.
4. More weight. 667g at 250x75mm versus 622g at 210x55mm for the standard Aria V2 — not a huge penalty for a DH-specific shock, but worth knowing if you’re a weight-conscious enduro rider trying to decide which variant actually fits your bike.

Left off that list: a different spring. Both shocks run the same AS3 dual-chamber architecture. EXT’s bet is that the tuning range of two independent air chambers is wide enough to cover trail riding and World Cup DH runs with the same basic spring, and the differences that matter are in the damper and the bottom-out circuit instead.

The Fitment Problem Nobody Talked About Until Now

Here’s the part of this launch that’s easy to miss if you’re only reading the air-vs-coil angle: the original Aria had a real compatibility problem. Its horizontal piggyback reservoir orientation reportedly kept it off several popular frames outright — the Specialized Enduro, Scott’s Genius and Ransom, and the Santa Cruz Megatower V2 among them, per Singletracks’ reporting on the redesign. That’s not a tuning nitpick. That’s “this shock physically doesn’t fit your bike,” which is a bad place for a $1,200 product to be.

The V2 redesign reorients the reservoir to sit vertically and shrinks the valve block’s footprint, which EXT and the outlets covering the launch both frame as the fix for that exact problem. It’s a quieter headline than “20% more bottom-out force,” but for anyone who tried to spec an Aria on a Megatower V2 and got told no, it’s arguably the bigger deal.

Does This Actually Threaten Coil Shocks on DH Bikes?

I’ll say what I’d say about any brand-new product with zero miles on it from an independent tester: the claims are specific and plausible, and specific claims from a brand with EXT’s reputation deserve more benefit of the doubt than a random startup’s would. EXT isn’t new to bottom-out circuits — the Storia’s hydraulic bottom-out adjustment is the reason it showed up in our own rear shock roundup as the most refined system we’d tested, coil or air, just priced out of reach for most riders. A 20% stronger version of a similar circuit, on an air shock that costs less than half what a Storia does, is a believable next step for this company specifically.

But “believable” isn’t “proven.” Coil’s advantage on DH tracks isn’t really about peak bottom-out force — it’s the linear, un-ramping feel through the middle of the stroke on repeated square-edged hits, the thing that makes a coil shock feel like it’s absorbing instead of building resistance. A stronger hydraulic circuit at the very end of travel doesn’t automatically fix mid-stroke character. EXT’s argument is that the AS3 spring’s independent chambers get closer to that linear feel than a single-chamber air spring can, which is a more interesting claim than the bottom-out number — and also the harder one to verify from a spec sheet. Nobody outside EXT’s own test riders has put laps on this shock yet. Blister’s first look and Bikerumor’s coverage are both working from the launch brief, not trail time.

Context matters here too. DH World Cup teams like Intense Factory Racing already run EXT hardware, which means this shock is entering a gravity racing scene where the brand has existing credibility — not launching cold into a category that’s never heard of it. That’s a real advantage over a brand-new entrant making the same claims. It’s also not a substitute for independent testing.

Pricing: Where the Aria V2 DH Lands

At $1,200 / €1,100, the Aria V2 DH sits well above the mainstream air shocks in our rear shock guide — roughly double the Fox Float X2 Factory’s ~$600 and triple the RockShox Deluxe Ultimate’s ~$380. It’s also meaningfully cheaper than EXT’s own Storia coil shock at $900-plus before you factor in a spring. For riders already shopping DH-specific gear in this price range — a BoXXer Ultimate fork or a top-tier brake — $1,200 for a rear shock isn’t an outlier. It’s just not an entry-level number, and EXT has never pretended otherwise.

Who Should Care About This

DH and heavy enduro riders currently running coil who’ve wondered if air has caught up. This is the shock built specifically to answer that question, from a brand with a legitimate bottom-out-control pedigree. Worth watching for independent test data once units start shipping.

Riders who’ve been frustrated by volume-reducer tokens on their current air shock. The AS3 architecture is a genuinely different approach to the support-vs-progression tradeoff, not just a marketing rename of the same single-chamber system.

Anyone who tried to spec the original Aria on a Specialized Enduro, Scott Genius/Ransom, or Santa Cruz Megatower V2 and got turned away. The fitment problem that kept this shock off plenty of frames is reportedly solved in the V2.

Who Should Skip This

Trail riders on bikes under 160mm. The DH-specific bottom-out tuning and extra weight are solving a problem your riding doesn’t have. The standard Aria V2, or a shock from our air vs. coil guide, makes more sense.

Anyone who needs verified trail performance before buying. This is a launch announcement, not a test. No outlet — including this one — has logged real descending time on the Aria V2 DH yet.

Budget-conscious buyers. $1,200 is a lot of money for a rear shock no matter how good the bottom-out circuit is. The Float X2 Factory and RockShox Vivid Coil both do real jobs for roughly half the price.

The Bottom Line

EXT built the Aria V2 DH to solve a specific, narrow problem: give DH riders the tunability of air without the harsh-ramp compromise that volume-reducer tokens create, and back it with a bottom-out circuit strong enough to make the coil-feel argument actually competitive. The AS3 dual-chamber spring is a real engineering difference, not a rebrand, and the frame-fitment fix on the redesigned shock body solves a problem that kept the original Aria off several popular bikes entirely. Whether 20% more end-stroke force closes the gap with coil’s mid-stroke feel is a question nobody can answer from a press release — ours included. At $1,200, this is a shock for riders who’ve already decided they want to spend serious money chasing coil feel from an air can. Everyone else should wait for someone to actually ride one.
