At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Mason X Hunt 650b Adventure Sport Disc Wheelset is a great choice for adding tyre volume and go-anywhere capability to your bike. With multiple axle and freehub options, a great build backed by a three-year warranty and decent parts supply, they earn their slight premium over the competition.

A few years back I reviewed the Mason X Hunt 4 Season Disc Wheelset, a 700c, 19mm internal-width alloy winner. Here we have the 650b update with a big-tyre friendly 25mm internal width.

The 650b part tells you what these wheels are for – rough surfaces and running fat tyres at low pressures. Knobbly or slick, either work well. Let's be clear here – 650b isn't a trend or fad – it's a return to a sensible wheelsize that was very common in the 1950s on long-distance touring bikes. Fat, supple tyres at low pressures roll well over rough roads. If you've got a frame and fork that can take the extra tyre width, 650b makes a lot of sense for people who like comfort, grip and puncture resistance.

Hunt has again delivered a package I can only fault for being a smidge (that's a metric smidge, or 59g) heavier than advertised at 1,653g including rotor lockrings. That weight for the price and durability is pretty good these days.

The rim is a standard hooked design with a drilled and taped rim bed. Hunt says not to exceed 50psi on 35mm tyres, 45psi on 45mm tyres and 40psi on anything larger. I rode the René Herse Umtanum Ridge 55mm tyre at 25-30psi and found they were plenty stable and grippy into corners.

You're unlikely to want to exceed those limits unless you're bikepacking and have a prop-forward level of weight, in which case you might want to look at other options. Hunt says 115kg is the upper limit for rider weight, so there you go.

Spokes are triple-butted stainless steel J-bend, going from 1.6mm in the middle to 2.2mm at the corrosion-resistant brass nipple for extra strength. The rims are asymmetrically drilled, so the spoke tension is closer to the same on both sides. I say closer, because checking with a tension meter the tension side to side is not balanced, as Hunt claim.

The hubs are Centre Lock disc format, and Hunt will sell you a set of 6-bolt adapters for £20. I've used these adapters for years and they work just fine.

After about a 1,000km of mostly gravelly off-roading (and powerwashing after every ride), I slid off the freehub to see nice fresh grease still coating the freehub pawls. Clearly the sealing is good, and maintenance – cleaning and greasing – is a quick, tool-free job.

The Hunt axle design is shoulderless, meaning the endcaps can be removed and the axle slid out without tools or [shudders] unseating a bearing. This makes for the interesting option of swapping cassettes without tools – leave it fixed to the freehub, and swap the entire assembly in seconds.

So you could swap a wheelset between Shimano and SRAM-equipped bikes tool-free. You could have a 'hilly' or 'bikepacking' cassette with a mega-range large cog, and another closer-range 'roadie' cassette for faster, flatter rides. So long as your rear mech can handle the tooth ranges required, swapping wheels or cassettes becomes the work of a minute or so.

These are 100% round wheels, didn't get less round during the test, and they stayed true and silent. They did the job without complaint or concern. The hub, with its four-pawl, 10-degree engagement always felt snappy when putting the power down, and the tubeless, pre-taped rim bed profile held different tyres just fine, even at low pressures. The included tubeless valves worked just fine too, and I was able to inject Orange Seal without any clogging.

With such bouncy rubber onboard it's a fruitless exercise blethering on about wheel stiffness or harshness; suffice to say I finished multiple long days feeling much happier than I would on 700c hoops at higher pressures.

Hunt offers a three-year warranty including free returns, and a 60-day right-of-return even if you've ridden them, so confident are they. They also do a 35% off crash-replacement policy if you stack it.

For me, Hunt has pretty much owned the 'second wheelset' market the last few years, and a key reason is its axle options. If you have older frames with QR axles, or a mix of QR at the back and thru-axle at the front, you can spec the necessary endcap or axle when you order. At £9.99 for an axle and the same for a set of endcaps, you can convert your wheels again later, should you need to, for under £20. Sets of QR skewers are £29.99.

Hunt also supplies all relevant bearings at £5.99 a pop, and the webshop makes ordering the right ones a breeze. There's not another wheel brand I know of making it so easy to source spares.


Looking at the competition, Stu really liked the Mavic Allroad SL wheelset at £589.99 and there's a non-'SL' version (1,840g), the Allroad 650b Disc Wheelset for £275. My personal caveat there, though, is that Mavic parts have been challenging to source at times.

There's a 650b option of the Fulcrum Rapid Red 5 wheelset that Stu also liked for £389.99, though that's roughly 100g heavier at 1,760g. Both the Mavics and Fulcrums use proprietary straight-pull spokes though, and in the case of the Mavics, proprietary captive nipples that can't be removed if damaged as the rim bed isn't drilled.


For me, Hunt has hit the sweet spot in the middle of the 650b wheelset Venn diagram covering price, support and performance. Unless you're looking for the lowest possible weight, or deeper rims for 'aero' reasons (and why bother, with rubber that fat?), I can't see why you'd go past the Adventure Sports.

A full 3 years from purchase date warranty is offered to the original purchaser only on all Hunt bike wheels against material or workmanship defects.

All HUNT wheels models have to pass our harsh cobbled-rolling-road tests for rider weight limits, please see here for more details. 115kgs is the upper recommended rider weight limit for these wheels. Please include the weight of any luggage in your total rider weight when choosing the correct wheels. If a rider is over 105Kgs then an experienced bike mechanic should check the wheel regularly and it is advisable to use minimum 30mm tyres at max 70psi as this will reduce the fatigue on the wheelset.

60 Day Ride & Return Period. If for any reason you wish to return the wheels for a full refund of your order you can do so up to a full 60 days after you receive them whether they have been ridden or not.

Rate the wheel for quality of construction:

Very well made; materials and finish are excellent.

Rate the wheel for performance:

On a tyre that fat it's hard to gauge lateral stiffness, but they certainly feel plenty strong.

Rate the wheel for durability:

Stayed true and silent, with no water ingress.

Rate the wheel for weight

About middle of the road, but you aren't paying for super-light.

Rate the wheel for value:

For the price, with options and support, they are fab value.

Did the wheels stay true? Any issues with spoke tension?

Yes true as a die, no issues with spokes.

How easy did you find it to fit tyres?

Tyres went on fine, popped on first time.

How did the wheel extras (eg skewers and rim tape) perform?

Rim tape was sealed from the start, the axles, endcaps and valves all worked fine.

Tell us how the wheel performed overall when used for its designed purpose

Can't fault them.

Tell us what you particularly liked about the wheel

As with all Hunt wheels it's hard to single out an individual aspect, the package is so well-rounded. But probably the ease of freehub swapping.

Tell us what you particularly disliked about the wheel

I'd like more internal width. 27-28mm would play better with the 50mm+ tyre widths now common.

How does the price compare to that of similar products in the market, including ones recently tested on

Some of the big manufacturers - Mavic, Fulcrum (Campagnolo) - offer cheaper 650b wheelsets.

Did you enjoy using the wheel? Yes

Would you consider buying the wheel? Yes

Would you recommend the wheel to a friend? Yes

Use this box to explain your overall score

These are well-built, well-specced wheels with multiple axle and freehub options, and they're backed by a three-year warranty. On price they're about equal to or more expensive than other 650b sets, but on every other aspect they win. They're excellent.

Very much agree on the parts availability. Fulcrum wheels are similarly adjustable with a standard hub across most of the range with endcaps and locknuts interchangeable (in theory). So you buy a wheelset you can then adapt to 15mm/12mm/QR, and even adjust the rear spacing between 135 & 142. The issue though is availability and cost. I bought a set of QR adapters for some Bianchi takeoffs recently (equivalent of the Racing 4 DB) and they cost £50 and had to be imported.

FSA are inbetween I find - endcaps are cheap but I'm not sure you can convert between 12 & 15mm. That's perhaps not important for a roadie but is if you're going greyside and want to run 15mm thru front axles on MTB forks (actually, haven't checked - are the new "gravel" suspension forks 12 or 15mm?)

I have the 2019 version of these with the Son deluxe hub option. Lovely wheels not huge sum of cash.

I run these with 47mm Senderos through winter and they make a perfect combo for slopping about in the worst of it. They've also done a fair amount of hammering over pretty nasty rocky fire tracks. I can't fault them at all. They get swapped out for Shamals and 40mm Terrenos when things dry out.
