The Hunt 40 Limitless Gravel Aero UD Carbon Spoke wheelset is a super-wide offering that sits at the very top of the British brand’s gravel range. Our test set is the lightweight UD Carbon Spoke variant but there is also a steel-spoked version for £370 less. At 1,328 grams they’re certainly light, but they have a bucket load of aero claims and are well up my list of gravel bike upgrades.

Gravel wheels are getting wider and in my opinion that’s a good thing, in fact for a few years now my wheels of choice have been the 40mm-wide 3T Discus 45|40 wheels. The benefits of wider rims come down to several factors: brands claim that they can better support wide tyres – offering more control, stability and even traction thanks to an increased tyre contact patch with the ground. There’s also a potential comfort benefit thanks to the increased air volume and aerodynamic advantages which we’ll get on to in a minute.

The Limitless gravel wheels are certainly wide – the internal measurements are 27mm for the front, 26mm for the rear, with external widths of 36mm and 35mm respectively. That’s not far off the depth of the wheels – 40mm front, and 41mm rear. For reference, it wasn’t so long ago that Enve’s AG25 wheels were considered wide, with their 33.5mm external width rims.

The downside of wheels this wide is that they’re normally a bit weighty, with the 3T Discus wheels having a claimed 1,665g weight, though they are a little deeper and even wider.

But the Hunts buck this weighty trend. The set we tested with carbon spokes tipped our scales at just 1,340g with rim tape fitted, which isn’t much more than the lightest gravel wheels in the business.

Contributing to that low weight are the UD carbon spokes, with each wheel getting 20. These weigh just 2.7g each, but Hunt says they’re not only light but that they reduce road vibration while increasing lateral responsiveness by a claimed 6%.

The wheels are certainly laterally stiff but, unlike earlier carbon-spoked wheelsets, they don’t feel overly harsh. That said, this isn’t usually as much of an issue on gravel wheels as it is on road wheels thanks to them usually being clad in higher-volume tyres.

During testing I used a few different sets of tyres, all of which fitted without issue. I’m also glad to see that Hunt has finally upgraded its rim tape to something with a bit more stick!

I usually opt for 45mm Schwalbe G-One tyres for most of my gravel rides, a tyre that paired well with the wide external rim without the ballooning you can get on narrower wheels.

Hunt says the rims are aerodynamically optimised around this tyre size, and while the wheels definitely do feel fast, it was the stability that impressed me most. Even on the open plains of Salisbury, the wheels resisted buffeting and allowed full focus on terrain ahead.

The Hunts also open up the opportunity to use even wider tyres (as long as your frame allows) and Hunt suggests 35-60mm will be no issue. Tyres this wide won’t be for everyone but it does appear to be the way that gravel pros are going for the biggest races and so this future proofing is certainly welcome.

I’d be remiss not to mention that the wheels are hookless – make of that what you will. For me, it’s far less of an issue for gravel and mountain bike wheels where the tyre volumes are higher and pressures are usually way below any limits. I certainly haven’t had any issues while using the Limitless wheels.

Value and rivals
So, the widths are good, the speed, stability and stiffness is impressive and the weight is right up there with the best. How do they stack up against the competition?
Well, we’ve recently tested a whole load of the latest wide gravel wheelsets so here goes.
The DT Swiss GRC 1100 Dicut wheels are more expensive than the Hunts at £2,398 and while they’re deeper at 50mm, at 1,575g they’re also significantly heavier. Given our test wheels are also much wider, the Hunts would be my pick between the two.
The Parcours FKT wheelset is also super wide and has a similar rim profile and internal width. Unlike the DT Swiss wheels, though, these are a fair bit cheaper than the Hunts. With both wheels specced with steel spokes and stainless steel bearings the 40 Limitless Gravels at their full RRP will set you back £1,479 while the Parcours retail for £1,249 – given the price difference I’d probably choose the latter.
But not so fast! The Hunts we tested have an ace up their sleeve: their incredibly low weight thanks to the carbon spokes. If you want this benefit you’re left with few that can come close.
I also mentioned the similarly priced 3T Discus 45/40 wheels, which are narrower and slightly shallower than the Hunts. And while I’d recommend the 3Ts for fast-rolling steady-state efforts, the Hunts are 325g lighter and I’d recommend them for everything else, as UK gravel usually involves plenty of changes of speed and for this the Hunts are the obvious choice.
Of course, being part of the Limitless range you do get a few other perks included in the price, for example, a three-year warranty and, perhaps more importantly, a Free Lifetime Crash Replacement coverage for original owners that also includes labour. As usual with Hunt you also get a set of high-quality wheelbags (which might be a tight fit if you use high volume gravel tyres), tubeless valves and a few spare spokes.
Conclusion
Overall, the 40 Limitless wheels are very competitive albeit not quite as stonkingly good value as we’ve grown accustomed to from the Sussex brand. If you want a super-wide, super-light wheelset then this carbon spoke wheelset has very few competitors that can match the performance, specs and quality of the Hunts. Oh… and there’s a Ceramicspeed bearing option for just £600 more… I’m unsure who in their right mind is selecting that option!
Verdict
Impressively light and wide option for tackling gravel at speed – but pricey if you go for carbon spokes

Make and model: Hunt 40 Limitless Gravel Aero UD Carbon Spoke
Size tested: 700c
Tell us what the wheel is for and who it’s aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Hunt says that it aimed “to create the fastest and most versatile gravel race wheelset, aerodynamically optimized for 40mm and 45mm tyre widths. The class-leading combination of wind tunnel-proven aerodynamic efficiency, crosswind stability, and low system weight (with UD Carbon Spokes) results in a true no-compromise wheelset for today’s fastest races.”
It’s certainly fast and it’s very light too. A versatile wheelset that’s bang up to date with modern trends.
Tell us some more about the technical aspects of the wheel?
From Hunt:
Mixed rim profiles
Front rim dimensions: 40mm deep | 36mm external width | 27mm internal width
Rear Rim dimensions: 41mm deep | 35mm external width | 26mm internal width
ETRTO compliant for use with 35c tyres and wider
Hookless TSS profile
Unidirectional T24/30 carbon fibre with 3K weave re-enforced spoke holes
Forged and CNC’d 6061-T6 heat treated aluminium alloy body hubs
Center-lock disc mount
48T ratchet: Dual sided ratchet rings, 7.5˚ engagement
Sealed cartridge stainless steel bearings
UD carbon fibre spokes
20 Spokes Front and Rear (2 cross lacing pattern)
Given their depth and width these are leading the pack when it comes to low-weight gravel wheels
This is very much a premium wheelset. The steel spoke variant is no doubt better value for the majority of riders (and I’d probably take this option). The super-lightweight carbon spoke option is for those of us looking for the ultimate in weight saving.
Did the wheels stay true? Any issues with spoke tension?
No issues – and the carbon spokes are replaceable.
How easy did you find it to fit tyres?
The super-wide rim does make it trickier to fit tyres than on some narrow gravel rims, but multiple sets of tyres went on without issue and tubeless setup was also no problem.
How did the wheel extras (eg skewers and rim tape) perform?
Very well, the rim tape has long been a weakness of Hunts but the company appears to have finally rectified it with these. The tubeless valves work well although the wheel bags are probably a bit small for purpose.
Tell us how the wheel performed overall when used for its designed purpose
Very well, the low weight makes the wheels feel lively on the rough and tumble of gravel, I had no issues with their durability, and they felt fast, stable and confidence inspiring.
Tell us what you particularly liked about the wheel
Their low weight and high lateral stiffness mean that they accelerate well – something that can make a gravel bike feel a lot more responsive.
Tell us what you particularly disliked about the wheel
There’s not a lot to dislike – there is the fact that CeramicSpeed bearings will set you back a further £600, but I won’t lose any sleep over that!
How does the price compare to that of similar products in the market, including ones recently tested on road.cc?
As mentioned in the review, this is a premium wheelset with a premium price tag to match. That said, they’re cheaper than wheels such as the DT Swiss GRC1100 and you’ll be hard pushed to find other gravel wheels this wide and light.
Did you enjoy using the wheel? Yes
Would you consider buying the wheel? Yes – though I think I’d probably go for the cheaper option with steel spokes
Would you recommend the wheel to a friend? Yes
Use this box to explain your overall score
They’re very good wheels – the 40 Limitless gravel wheels are fast, stable and suitably wide. The main appeal will be their low weight.

Serious question.
Serious question.
What makes a wheelset ‘gravel’ as opposed to regular road wheels? They are wider for sure, but isnt that the current trend for all road wheels? I will often read on here and other cycling sites about the adoption of 30mm , 32mm and even 34m and wider still on road bikes, if your frame will acommodate them. So are they ‘Gravel specific’ or just optimised for such bikes?Also if I wish to use wider tyres do I need these or could I use rims that are marketed as roadwheels? I know what I can use but for those less informed or who havent researched them as much, I feel in calling a product something like this it risks being overlooked by potential buyers. Ideally, if they are light, aero and wide to accomodate tyre that will improve speed and comfort on my regular road bike I would be interested but then might very much overlook them just on a name.
There certainly is a grey
There certainly is a grey area, and as you say that grey area is arguably larger than ever given the marketing of “all road” bikes, and ever-wider tyre clearance even on supposed “road” bikes.
These wheels have an internal rim width of 26-27mm, which means the absolute minimum (labelled) tyre size is 35mm. I would say 35mm is still very much on the upper end of what people would choose for pure “road” riding, and on the upper end of what most “road” bikes will fit.
The other factor is strength/testing standards. This is something a lot of manufacturers are not very open about (see e.g. the recent PlanetX debacle). For these wheels, Hunt claim they have been tested to “gravel wheel protocols which far exceed industry-standard ISO testing” – although I can’t find any information on exactly what those protocols are, or how they compare to ISO standards. As a general rule, however, I would expect “gravel” wheels to be built tougher than “road” wheels, and normally have better sealed bearings etc. But as I said, manufacturers often don’t actually specify much detail about that kind of thing, so mostly it’s inference or gleaned from the little tidbits they do share (such as the testing protocol quote given above).
Marketing and price tag is
Marketing and price tag is what makes them gravel other then that there both round.
