On 30 June 2026, Zipp did something the big American wheel brands have resisted for a decade. It put a genuinely pro-derived 50mm aero wheelset on sale for £985 / $1,300 / €1,100. One month on from launch, this guide covers what the new Zipp 404 S actually gives you, the one catch (hookless rims) that should decide whether you buy it, and how it compares with Hunt, Elitewheels, Winspace and the rest of the 2026 budget carbon field. If you're shopping for your first carbon wheelset, everything you need to make the call is below, with real prices and real numbers.

Key takeaways

- The £1,000 wall just cracked. The Zipp 404 S launched 30 June 2026 at £985 / $1,300 / €1,100: a Firecrest-derived 50mm rim at roughly half the price of the 404 Firecrest (€1,899).

- It replaces the 303 S, jumps from 45mm to 50mm of depth at the same £985 the 303 S sold for, and Zipp claims it saves about 2 watts over the wheel it replaces.

- The catch is hookless. You must run 28–39mm hookless-approved tubeless tyres at no more than 5.0 bar / 73 psi. Your old clinchers and inner tubes won't work. If that's a dealbreaker, the hooked Hunt 50 Carbon Disc (£899, 1,464g) is the no-restrictions alternative.

- The warranty is the quiet headline. Zipp's lifetime warranty covers structural damage sustained while riding, not just manufacturing defects. That's stronger cover than Elitewheels (3 years) or Black Inc (2 years).

- Best overall value for tubeless riders: 404 S. Best no-restrictions pick: Hunt 50 Carbon Disc. Best weight-per-dollar: Elitewheels Drive 50D II ($1,299, 1,300g).

What's New in 2026: The Zipp 404 S at a Glance

The 404 S is the newest wheel in Zipp's range and the cheapest way ever to buy the brand's flagship aero shape. It went on sale 30 June 2026 at £985 in the UK, $1,300 in the US and €1,100 in the EU (or €530 front / €570 rear if you buy wheels individually). That price only makes sense once you look at what sits above it. The premium 404 Firecrest costs €1,899, roughly double, and until this summer the S-Series topped out with the 45mm-deep 303 S.

That 303 S is exactly what the 404 S replaces. Zipp dropped the 45mm wheel from the range, moved the S-Series flagship to a 50mm-deep rim derived from the WorldTour-proven Firecrest profile, and held the price at the same £985 the 303 S sold for. More depth, same money, and Zipp claims the 404 S saves about 2 watts over the outgoing 303 S.

Zipp isn't being shy about the competitive framing either. Nathan Schickel of Zipp claims the 404 S's aerodynamics beat comparable-depth wheels from Enve and Scope "costing more than twice as much", as well as the Hunt 50 wheelset. Road.cc's launch headline summed up the positioning: industry-leading aero performance for under £1,000. To be clear, these are manufacturer claims, not independent wind-tunnel data. One month after launch, no outlet has published long-term test results yet. But you don't name your rivals on the record unless you're picking a fight.

Why now? Because the value segment stopped being a niche. Spanish outlet Todomountainbike put it bluntly: the 404 S is Zipp's answer to "Asian competition", meaning direct-to-consumer brands like Elitewheels and Winspace that sell 1,300g carbon-spoked wheelsets for $1,299 and have been pulling first-time carbon buyers away from the legacy brands for years. Hunt, meanwhile, has owned the UK value market with hooked, sensibly priced wheels. The 404 S is the first time Zipp has met them all head-on at their own price point.

One positioning note before we go further. Zipp is explicit that the 404 S is a road and, at most, all-road wheel, not a gravel wheel. SRAM's Marie Didier points riders who want aero gravel toward the 303 XPLR S instead. If your riding is mostly unpaved, this isn't your wheelset.

Zipp 404 S Full Specification

Here's the complete 404 S spec sheet, assembled from launch coverage. Two numbers define this wheel in 2026 terms: the 23mm internal rim width (optimised around 28mm tyres, in line with the wide-tyre direction the whole industry has taken) and the hookless "TSS" rim (Tubeless Straight Side, Zipp's name for its hookless bead design). That second one drives every tyre rule in the next section.

A few of these lines deserve translation for first-time carbon buyers. Points of engagement (POE) is how many positions the freehub can catch in one revolution. 36 POE means roughly 10 degrees of crank rotation before the hub engages when you start pedalling, which is ordinary rather than exceptional (Hunt's flagship hub engages every 7.5 degrees). It's one of the places Zipp saved money. The Sapim CX-Sprint J-bend spokes are another deliberately pragmatic choice: J-bend spokes are easy for any bike shop to source and replace, unlike the proprietary straight-pull or carbon spokes on some rivals. Boring, in a good way.

The claimed 1,585g includes rim tape and tubeless valves, which is honest weighing. Many brands quote bare-rim figures. (Zipp's Japanese arm lists 1,565g; sources differ slightly, so treat 1,585g as the headline number.) For context, that's about 120g heavier than the hooked Hunt 50 Carbon Disc and nearly 300g heavier than Elitewheels' carbon-spoked Drive 50D II. On a 50mm aero wheel, weight matters less than the marketing suggests, because aerodynamic drag dwarfs a couple of hundred grams everywhere except long climbs. Still, it's a real difference and we won't pretend otherwise.

The 115kg system weight limit covers rider, bike, bottles and luggage combined. Heavier riders should do that arithmetic before ordering.

The Hookless Catch: What First-Time Carbon Buyers Must Know

Read this section twice if you read nothing else, because the 404 S's price is only a bargain if you can live with its rim design. Hookless rims have straight internal walls with no bead hook, the small lip that traditional "hooked" rims use to lock the tyre bead in place. Removing the hook simplifies carbon manufacturing (part of how Zipp hits £985), but it transfers the job of keeping the tyre on the rim almost entirely to air pressure limits and tyre fit tolerances.

The rules that follow are not suggestions. Under the ETRTO/ISO standard, hookless road rims are capped at 72.5 psi / 5.0 bar with 25–29mm tyres, and tyres on hookless rims are only required to resist blowing off at 110% of max pressure, versus 150% for hooked rims. That is a much thinner safety margin. Wider tyres get lower ceilings still: 65 psi for 30–34mm tyres, 58 psi for 35–39mm. Zipp's own limits for the 404 S mirror this exactly, at 5.0 / 4.5 / 4.0 bar by tyre width.

The practical consequences, in plain English:

Hookless compatibility checklist — you can run the 404 S if all five are true:

1. You will ride tubeless, with sealant, not clinchers with inner tubes. Standard non-tubeless clincher tyres cannot be used on hookless rims even with a tube; the bead can stretch and blow off.
2. Your tyres are 28mm or wider. Schwalbe and Vittoria both recommend 28mm as the minimum tyre width on hookless rims, and general guidance is a tyre at least 5mm wider than the rim's internal width (23mm here, so 28mm minimum).
3. Your tyres appear on Zipp's official hookless tyre-compatibility list, maintained on its support site. Check before you buy tyres, not after.
4. You're comfortable riding at 5.0 bar / 73 psi or less. With modern 28mm tubeless tyres this is genuinely the fast pressure anyway for most rider weights. But if you're a high-pressure traditionalist, this platform is not for you.
5. You (or your pump) can be trusted not to exceed the limit. There is no margin for "a bit extra for the race."

Be aware that hookless remains genuinely controversial. Silca CEO Josh Poertner, a former chairman of the Bicycle Wheel Technical Committee, has called road hookless "a scam" and a safety risk, citing tubeless tyres that blew off certain hookless rims at 78–80 psi in his testing. And in February 2026, Fabio Jakobsen's crash at the UAE Tour reopened the hookless safety debate inside the pro peloton itself.

My balanced reading of the evidence: run within spec, meaning 28mm-plus approved tubeless tyres under 5 bar, and hookless has a large installed base riding without incident. That's precisely how the 404 S is designed to be used, aero-optimised around a 28mm tyre. The failures that fuel the controversy overwhelmingly involve pressure over the limit or unapproved tyre-rim combinations. But if the checklist above gave you pause even once, buy a hooked wheelset instead. There are excellent ones below, and no watt saving is worth a tyre you're not confident in.

Zipp 404 S vs 404 Firecrest vs the Old 303 S: Which Zipp Should You Buy?

If you've searched "zipp 404 s vs 404 firecrest", here's the direct answer with the 2026 numbers.

404 S vs 404 Firecrest. The Firecrest is 58mm deep to the S's 50mm, a claimed 1,559g (BikeRadar's scales said 1,527g), and carries Zipp's nicer hub internals. It costs €1,899, roughly double the price. The extra ~£900 buys you a deeper, faster rim in a straight-line aero sense, a slightly lighter build, and top-tier finishing. What it doesn't buy you is a different rim philosophy: both are 23mm-internal hookless wheels with the same tyre rules. For a first carbon wheelset, the honest advice is that the Firecrest's gains are marginal against a near-£900 saving. The 404 S exists precisely because Zipp knows most riders should not pay double.

404 S vs the old 303 S. The 303 S is gone from the range, but stock will circulate at discounts through 2026. The maths is simple: at equal money, the 404 S is the better wheel, 5mm deeper and about 2 watts faster by Zipp's own claim. If you find a 303 S at a genuinely deep discount and you ride hilly terrain where 45mm suits you, it remains a fine wheelset with the same hubs (the 76/176 hubset is shared between the two). At anything close to RRP, buy the 404 S.

The middle path. The 303 Firecrest at £1,350 sits between the two 404s: shallower, more all-road-oriented, with Firecrest-level construction. Its warranty terms are worth noting because they clarify Zipp's policy generally. Lifetime warranty to the original owner, 3-year crash replacement, and a crash-replacement rim at about 40% of retail. Combined with the 404 S's own cover, a lifetime warranty that includes structural damage sustained while riding within intended use, Zipp's paperwork is the strongest in this price bracket, full stop.

The Best Budget Carbon Wheelsets of 2026: The Full Field

Now the roundup. Every price below was checked in July 2026. The table is ordered by price. The rows below £1,500 are the true rivals, and the bottom rows show what doubling your budget actually buys, which is useful calibration before you spend.

Hunt 50 Carbon Disc (£899) is the keep-it-simple pick. Fifty millimetres deep, 1,464g, and crucially hooked: it takes any tyre, tubeless or clincher with a tube, at any sensible pressure. For a first carbon wheelset with zero compatibility homework, this is the safest buy on the list, and it undercuts the Zipp by £86.

Elitewheels Drive 50D II ($1,299) is the weight-per-dollar king. A 50mm, hooked, carbon-spoked wheelset at a claimed 1,300g ±30g (measured without tape and valves, note) with a 3-year warranty. On paper it embarrasses everything else here. The trade-offs are the direct-from-China support model, meaning warranty service by courier rather than a local dealer, and carbon spokes a local shop can't replace. This is the brand pressure that produced the 404 S in the first place.

Hunt 54 Aerodynamicist (€1,399 list) is the deal-watcher's wheel. It was discounted to €909 on Hunt's EU site in July 2026; at that money, a 54mm, 1,524g hooked wheelset is superb value. (Its deeper sibling, the 54_58 Aerodynamicist, runs 1,468g at €1,459.)

Winspace Lún Hyper 50 (~$1,699) is a well-regarded China-direct alternative, 50mm front / 55mm rear, ~1,420g, hooked. At that price, though, it now fights the discounted big brands rather than undercutting them.

The stretch tier. Hunt's Sub50 Limitless (£1,479, hookless, 1,380g), the flagship Hunt 5AM Limitless (£1,999, 1,212g, 58/55mm, carbon spokes, and a 48-tooth H_Ratchet hub engaging every 7.5°; $2,599 in the US, or £2,489/$3,199 with CeramicSpeed bearings), Parcours' Strade GT (£2,499, ~1,140g, 60T hub) and Black Inc's 48|58 ($3,199, 1,290g, CeramicSpeed bearings, but only a 2-year warranty). The pattern is hard to miss: doubling or tripling the budget buys 200–450g and posher hubs, not a different category of speed.

Zipp 404 S vs Hunt: The Head-to-Head Most Buyers Face

For UK and EU buyers especially, the real-world decision usually collapses to Zipp vs Hunt. Here's the honest ledger.

Zipp 404 S vs Hunt 50 Carbon Disc. The Hunt is £86 cheaper (£899 vs £985, and it has been seen from £799) and about 120g lighter (1,464g vs 1,585g). It is also hooked, which means no tyre-compatibility lists, no 73 psi ceiling, and inner tubes as a get-home option without caveats. The Zipp counters on three fronts. Zipp claims the 404 S is aerodynamically superior to the Hunt 50 (a manufacturer claim, but one made on the record against a named competitor). Its 23mm internal rim is a millimetre wider and squarely optimised for the 28mm-tubeless direction the road market has taken. And its lifetime warranty including structural riding damage plus crash replacement simply outclasses the support terms of anything else under £1,000. For a nervous first-time carbon buyer, that warranty is worth real money. A destroyed rim on most brands means a new wheel at your expense.

The decision rule: committed tubeless rider who wants the strongest paperwork and pro-brand aero → Zipp 404 S. Want zero restrictions, lower weight and a lower price → Hunt 50 Carbon Disc. Neither choice is wrong; they're optimised for different owners.

One tier up: the Hunt Limitless wheels. If your budget stretches past £1,400, Hunt's own hookless flagship-lite, the Sub50 Limitless (from £1,479, 49.5mm, 1,380g, 40T ratchet), beats the 404 S on weight by 200g, for £500 more. And the halo Hunt 5AM Limitless (£1,999, 1,212g, 58mm front / 55mm rear) is the wheel for riders who want near-superbike numbers without superbike prices: carbon spokes, a 7.5°-engagement 48T ratchet hub, and hooked rims. Against the 5AM, the 404 S's case is purely financial. You could buy the Zipps and a power meter for the same outlay. Against the Sub50, the Zipp's warranty and £500 saving keep it firmly in the argument.

The bigger point for this head-to-head: Zipp went after Hunt by name at launch. That tells you who Zipp thinks its real competitor is in 2026, and it means UK buyers in particular get to play two motivated brands against each other. Watch both prices. Hunt discounts aggressively (the 54 Aerodynamicist at €909 proves it), and Zipp has never played at this price before.

Who Should Buy the Zipp 404 S — and Who Shouldn't

Strip away the launch noise and the 404 S decision comes down to a short, honest framework. Work through it in order.

Buy the Zipp 404 S if all of these describe you:

• You run, or are happy to switch to, 28mm+ tubeless tyres from Zipp's approved list, at 5 bar / 73 psi or below.
• You want big-brand aero credibility, a Firecrest-derived and WorldTour-proven rim shape, at the lowest price Zipp has ever charged for it.
• The lifetime warranty covering riding damage matters to you. It should: it's the best support package under £1,000 in 2026.
• Your total system weight, rider plus bike plus kit, is comfortably under 115kg.
• Your riding is road or fast all-road. (Gravel? Zipp itself says no. The 303 XPLR S is the aero gravel option.)

Skip the 404 S — and here's where to go instead — if any of these apply:

• You want to keep using inner tubes, standard clinchers, or narrow high-pressure tyres. Hookless makes all three a hard no. → Hunt 50 Carbon Disc, £899, hooked.
• You're chasing minimum weight per pound spent. The 404 S is 1,585g; the same money-class gets you 1,300g elsewhere. → Elitewheels Drive 50D II, $1,299, if you accept direct-brand support; → Hunt Sub50 Limitless, £1,479, if you don't.
• You're near the 115kg system limit or routinely load the bike heavily. Do the maths honestly, including luggage.
• You mostly ride gravel. Wrong wheel, per the manufacturer itself.
• The hookless checklist earlier made you hesitate. Trust that instinct. A wheelset you second-guess at 70 km/h is a bad purchase at any price.

A worked example makes the framework concrete. Take a 78kg rider on a disc-brake endurance bike, already on 28mm tubeless, riding fast club runs and the odd flat race. That's the textbook 404 S buyer: the aero claim, the warranty and the price all line up, and the pressure ceiling costs them nothing because their optimal pressure is under 5 bar anyway. Now take a 95kg rider who punctures often, carries a tube, and likes 80 psi in 25mm tyres. Every single spec of the 404 S fights that rider, and the Hunt 50 serves them better for £86 less. Same budget, opposite answers. Which is exactly why "is it good?" is the wrong question and "is it good for me?" is the right one.

First Carbon Wheelset Buyer's Checklist: Five Checks Before You Pay

Whichever wheelset the flowchart pointed you to, run these five checks before checkout. They catch the expensive mistakes first-time carbon buyers make most often.

1. Confirm tyre compatibility in writing. For hookless wheels (404 S, Hunt Sub50 Limitless), your exact tyre model and width must appear on the manufacturer's approved list. Zipp maintains its official list on its support site. For hooked wheels, confirm tubeless-readiness if you plan to ditch tubes. Never assume a tyre you own today carries over.
2. Check the freehub matches your groupset. The 404 S ships with Shimano HG11 or SRAM XDR options; Campagnolo is sold separately in some markets. Ordering the wrong freehub adds weeks of waiting and courier fees. While you're at it, confirm axle standards. The 404 S uses 12x100mm front / 12x142mm rear, standard for modern disc road bikes but not for older frames.
3. Verify rotor mount type. The 404 S is Center Lock; if your current rotors are 6-bolt, budget for new rotors or lockring adapters.
4. Do the system-weight arithmetic. Rider + bike + bottles + bag versus the stated limit (115kg for the 404 S). If you're within 10kg of the ceiling, consider a wheelset with a higher limit or more spokes.
5. Read the warranty like a contract, because it is one. The gap between Zipp's lifetime-including-ride-damage cover, Elitewheels' 3 years, and Black Inc's 2 years is the difference between a free replacement and a four-figure bill after one pothole. Also check crash-replacement terms; Zipp's programme offers replacement rims at about 40% of retail. For budget wheels especially, the warranty is part of the price.

Pro tip: buy your first tubeless setup kit (sealant, valves if not included, a decent tubeless-compatible pump or booster) in the same order as the wheels. The 404 S ships with rim tape and valves fitted, one genuine convenience of the 1,585g as-delivered weight, but sealant and a plug kit are on you. Nothing sours a new-wheel day like a garage full of parts that can't be mounted.

Frequently Asked Questions

Q: How much does the Zipp 404 S cost and when did it come out? A: The Zipp 404 S went on sale on 30 June 2026 at £985 / $1,300 / €1,100 per pair (front €530, rear €570 individually). It's the first Zipp wheelset with the Firecrest-derived aero profile to be priced under £1,000.

Q: What does the Zipp 404 S replace? A: It replaces the 45mm-deep Zipp 303 S in the range, at the same £985 price the 303 S sold for. The 404 S is 50mm deep and Zipp claims it saves about 2 watts over the 303 S.

Q: How heavy is the Zipp 404 S? A: 1,585g per pair claimed, including rim tape and tubeless valves (Zipp's Japanese site lists 1,565g; sources differ slightly). That's about 120g heavier than the Hunt 50 Carbon Disc (1,464g) and 26g heavier than the 58mm-deep 404 Firecrest (1,559g claimed).

Q: Are hookless rims safe for road riding? A: Within spec, yes. That means hookless-approved tubeless tyres of 28mm or wider, never exceeding the ETRTO ceiling of 72.5 psi / 5.0 bar. The controversy (Silca's Josh Poertner calling road hookless "a scam" after tyres blew off test rims at 78–80 psi, and Fabio Jakobsen's February 2026 UAE Tour crash) centres on the thinner blow-off margin, 110% of max pressure versus 150% for hooked rims. That's why staying inside the limits is non-negotiable. If you won't commit to those rules, buy a hooked wheelset instead.

Q: What tyres can I run on the Zipp 404 S? A: 28–39mm hookless-approved tubeless tyres only, checked against Zipp's official compatibility list. Maximum pressures step down with width: 5.0 bar / 73 psi for 28–29mm, 4.5 bar for 30–34mm, 4.0 bar for 35–39mm. Standard non-tubeless clinchers cannot be used, even with an inner tube. The bead can stretch and blow off a hookless rim.

Q: Is the Zipp 404 S good for gravel? A: No. Zipp positions it explicitly as a road and, at most, all-road wheelset. SRAM's Marie Didier directs riders who want an aero gravel wheel to the Zipp 303 XPLR S instead, despite the 404 S accepting tyres up to 39mm.

Q: What warranty does the Zipp 404 S have? A: A lifetime warranty that covers not only manufacturing defects but structural damage sustained while riding within intended use, plus a crash-replacement programme (Zipp's crash-replacement terms have included rims at about 40% of retail). That's the strongest cover of any wheelset in this price bracket. Elitewheels offers 3 years and Black Inc 2 years by comparison.

Q: Are Chinese carbon wheels like Elitewheels worth it in 2026? A: On paper, emphatically: the Elitewheels Drive 50D II delivers a 1,300g ±30g, carbon-spoked, hooked 50mm wheelset for $1,299 with a 3-year warranty. No legacy brand matches those numbers at the price. The trade-offs are courier-based warranty service instead of a dealer network and proprietary carbon spokes your local shop can't replace. That competitive pressure is, by industry consensus, exactly why the 404 S exists at £985.

The Bottom Line: The Moment Big-Brand Aero Got Affordable

The Zipp 404 S is the budget wheelset launch of 2026 worth caring about, and not because it's the lightest or even the cheapest option here. It's because a WorldTour-pedigree American brand looked at the direct-to-consumer wheels eating its lunch and decided £985 was a price it had to fight at. A Firecrest-shaped 50mm rim, honest as-delivered weight, sensible serviceable spokes, and the best warranty under £1,000: that's a genuinely strong first carbon wheelset. The aero claims against Enve, Scope and Hunt are unverified for now, but they come from a brand with wind-tunnel credibility to lose.

The deciding factor shouldn't be the price, though. It should be the rim. Commit happily to 28mm-plus approved tubeless tyres under 5 bar, and the 404 S is our best overall value pick of the 2026 budget field. Want carbon speed with zero compatibility rules? The Hunt 50 Carbon Disc at £899 remains the smart, hooked, no-homework alternative. Chasing grams per pound, the Elitewheels Drive 50D II at $1,299 and 1,300g is untouchable, if you accept the direct-brand support model.

Whichever way you go, you're buying into the best moment the budget carbon market has ever offered. The direct brands forced the price down, Zipp finally answered, and the winner is whoever's shopping this summer. Pick the wheel whose rules you'll actually follow, run the buyer's checklist before you pay, and enjoy the free speed.
