Nukeproof Launches New Horizon Pro Wheel Range

May 25, 2023

Press Release: Nukeproof

After what seems like an eternity of design, development, and testing, Nukeproof launches its all-new Horizon PRO wheel range.

Nukeproof has a proud history of creating high-performance hubs and wheels, from the legendary carbon-shelled Atom Bomb hubs in the 1990s to the more recent Generator, Neutron, and Horizon wheelsets.


Launched in 2020, the current Horizon V2 wheelsets have elevated Nukeproof wheels to the next level of performance. The V2 has been tested at the highest level, between the tape at both the Enduro and Downhill World Cup with the Nukeproof-SRAM Factory team. It has gone on to become a huge favourite with ranks of privateers and riders. Key reasons include the strength, reliability, and serviceability of the V2. But here at Nukeproof, we are always looking for the next step in performance.

Welcome to the Horizon PRO:


Designed as an all-new wheelset created for riders who are looking for the ultimate alloy trail wheel. Using the Horizon V2 as a base, our designers took a fine-tooth comb to the Horizon V2 to make several incremental improvements. The main aim of the PRO was to reduce rotational mass and make a lighter wheelset for trail and enduro riders and racers.

The result is a ground-up design and an all-new front and rear wheel. The PRO wheels are lighter, more compliant and use an all-new high-performance rapid-engagement ratchet hub for the rear wheel. In raw terms, the Horizon PRO offers riders a 9-10% (depending on wheel size combination) weight reduction over our Horizon V2 wheelsets.

All the improvements make the Horizon PRO perfect for trail and enduro riders searching for the ultimate alloy wheelset.

New Nukeproof Horizon PRO Hub:

At the heart of the Horizon PRO is an all-new hub housing the new 54T engagement ratchet mechanism. Why move to a ratchet system? For both size and weight. The compact dimensions of the ratchet system allow for a reduction in the overall size of the hub. Less material means a reduction in mass. There are also performance benefits from a ratchet system. A fast and smooth engagement provides a more responsive ride and also reduces lost energy in the hub.


To further reduce the overall dimensions of the hub, we chose to use double butted straight-pull spokes (2.0mm-1.8mm-2.0mm). These spokes allow for the optimizing of the hub shell dimensions by machining away any unrequired material.

With the new ratchet system, engagement of each tooth is simultaneous. This evenly distributes the force across a larger surface area and reduces wear, ensuring reliability.
The result is a sleek shell that looks stunning, hugs the axle and is strong and reliable.

Hand-Built and Tensioned:

To further reduce weight, we have reduced the spoke count of the wheels to 28. This is thanks to the increased tension and strength by using straight pull spokes (vs a J-Bend).
Each Horizon PRO wheel is laced by hand in a 3x spoke pattern. The Horizon PRO rim is made from dynamically aged magnesium-silicon enriched alloy blend. This alloy produces the stiffness and hardness like 7-series alloy, but with the ductility and yield properties of a 6-series alloy. Each rim is sleeved to join to ensure a strong and consistent level of strength around the rim. Overall, this offers an incredible blend of stiffness, compliance, strength, and weight.

Both 29” and 27.5” wheels are available.


The Horizon PRO rim is designed to offer maximum strength, comfort and grip from 2.3" to 2.5" tires. Numerous lab and trail tests led to the use of a 30mm internal width rim to optimize the tire profile of most modern tires.
Available in 12x148mm Boost only. To support spare parts for riders, the front and rear wheels share the same rim and straight-pull spoke design. Each rim has a tough anodized black sandblasted finish with silver decals to match the hub.

Enduro ABEC 5 Bearings:


After testing various brands of bearings, Nukeproof chose to use Enduro ABEC 5 bearings in the rear wheel. These bearings have the “LLU/LLB” seal type, which uses two lips that make light contact in a groove to create a labyrinth where the water or dirt has a more difficult time penetrating.

LLU seals are similar, only the contact pressure or interference fit is greater to seal better. Enduro bearings have 80% grease fill on both sides, whereas most other bearings have 35% grease fill on one side. This delivers full coverage, so there are no dry areas as well as avoiding metal on metal contact or wear. Note: the axle may feel tight when new but will free up when ridden.

What's Included in the box?

All wheels are sold individually, allowing riders to pick wheels to suit their frame. The tubeless valve supplied is compatible with Nukeproof ARD and other tire inserts, and the presta valve cap has a core remover built in. All riders need to do is fit a tire of choice, add sealant, and go ride.


To back riders up a full range of spare parts, hub, freehub conversions kits, spokes, rims, and maintenance tools are available.



Horizon PRO wheels are available now and will be heading out to Nukeproof retailers over the coming weeks (US availability mid-June). If you are interested, check out your local Nukeproof retailer or online.

Front - SRP: £229.99 / USA $299 / Europe €264.99
Rear - SRP: £369.99 / USA $399 / Europe €429.99

Front - 27.5: 823g (without valves) // 29: 863g (without valves)
Rear - 27.5 MS: 943g (without valves) // 29 MS: 988g (without valves)

 Enduro bearings aren’t a selling point. I would much rather seen bearings from a reputable bearing brand like SKF.

Also, I hate straight-pull spokes for tension service. Nothing like having them try to rotate while you’re adjusting the nipples, so now you get to pull out another tool to do a simple adjustment.

 I've had multiple sets of Nukeproof wheels. Their hubs have never failed me (and I've had multiple other hubs fail me via stripped ratchet rings or blown up pawls or roasted bearings from misalignment or broken axles). Their rims seem really tough when it comes to alloy, they're second only to the WAO wheels I also have and they're built well from the factory and reasonably priced.

It's not hard to true straight pull spokes. Knipex pliers in one hand, spoke wrench in the other. Grip the spoke with the pliers, spin your spoke wrench. Yeah it's another tool, but it's a few minutes of your time. Also I've had J-bend break at the bend a few times (not that it's common), but never had that problem with straight pull.

 I had an old Hope Pro2 that kept eating bearings every 1K miles. After replacing them 3 times I was at the point of replacing the hub but decided to give Enduro Max cageless bearings a shot. Just retired the wheel set/hub and those bearings lasted 7 years and 8K miles and were still spinning like new. They say they are not recommended for hubs but they worked great for me, never noticed any extra drag and they spun as smooth as the new Hope Pro4 that replaced it.

 I've built more than 10 sets of straight pull wheel sets and once the spokes are lightly tensioned I've had zero issues with the spokes rotating.

 @rickybobby19: Maybe I'm just clumsy but I already use two hands when building or truing a wheel with J-bend nipples. When truing, usually one hand holding the tool, the other holding the rim to rotate it in the correct position. I can't see myself holding that plier too. I have no issues with butted J-bend spokes (I prefer DT Swiss Alpine III) so I can't see how straight pull spokes would make life better for me.

Back when I started riding mtb I also rode with a guy who had Shimano wheels where the head of the spokes protruded the side of the rim and the nipples would be near the hub. Not sure whether it was a commercial product or a prototype. He is a nephew of Bart Brentjens and most of the stuff he was using was a hand me down. But it seemed like a clever idea to me. Weight (of the nipples) closer to the hub, no drills in the rim to tape. Minor downside nowadays would be that the brake rotor and cassette would be in the way for a quick tune up, but nothing that should add more than a few minutes to the job. Especially with tubeless tires nowadays, I can still see this make a lot of sense. Anyone here had experience with these wheels and/or is anyone aware why they quit making these (if they ever got beyond the protype stage)?

Here’s a quick way to get downvoted-
Enduro bearings are a commonly used bearing for many Mtn bike hubs, as are pressure washers.
Use a pressure washer tight to any wheel bearing, and it becomes cheap junk.

 Increased tension of straightpull instead of J-bend is BS. Tension can be exactly the same on both layouts, because the limiting factor is the rim. And stiffness will probably be worse without high hub flanges. Also AlMgSi literally is 6-series aluminum alloy.

 Right? I don't get why they're touting the "ductility and yield properties of a 6-series alloy" :shrug:

 Wasn't Al6069T6 (which is what Hunt uses) pretty good? What other alloy were you looking for as a rim? Al6xxx is good for extrusion, which is how rims are made. I don't think you can extrude Al7xxx into these complex shapes.

 Their marketing team really put in the hours for this one.

Reading through it I was thinking "house brand DT Swiss hubs with run of the mill alloy rims. Most of the weight savings is from the hub choice and going down in spoke count."

My exact first thought as well.

 There's always better wheels but I like Nukeproof as a brand and their stuff is usually good quality. I'd buy a pair to throw on my Reactor frame. I just wish they'd get better USA distribution. They have a US site now but often things are out of stock compared to availability from CRC.

 For what it's worth I bought a set of the Horizon V2's as a hold over whilst my carbon wheels were in for a warranty repair. I liked them so much that when I got the Carbon ones rolling again, I just sold them and kept the Horizons. They were very affordable (like they cost less than half the RRP of my carbon ones, and CRC had them as a package with sealant and the Ard inserts) and they turned out to be a brilliant ride- very compliant without being soft and the hub is really crisp. Not sure I would pay to upgrade to this Pro model, but would consider in insolation.

 Please put "Trigger Warning" on these going forward. The photo of the vintage nuke proof hub made me relive trying to race with those hubs in the early 90's.

 The new ratchet freehub might be an improvement if it's as good as a DT, but lower spoke count and straight-pull seems a backward step to me. My new Hv2 rear lost all it's tension on a recent week long bike trip, but it stayed true. Not sure a 28-hole wheel would have survived the same beating.

 I've got a NP Horizon rear wheel and it's held up great. Cheap and durable. Picked up WAO's, so now designated as a spare, but I'd buy it again.

 I can't wait to buy these 60%-off from Wiggle or CR.

All joking aside, the cheap Neutron V2s I picked up as backups have held up fine. The front only cost me $124CAD (~$90USD). They set up tubeless perfectly with the included valve. Insane value.
  • 6 4
 Meh... they look nice, but $700 is a premium price for an AL wheelset with house hubs and only a 2-year warranty. Several AL wheels manufacturers are offering lifetime warranties now... hard for these Nukeproof wheels to compete with that.
  • 3 1
 Yeah, for that price, I'm buying Reserve wheels with a lifetime warranty and the slick filmore valves.

 The idea is to buy them on 40 or 50% discount in one of CRC/Wiggle's many sales.

 "reduced the spoke count of the wheels to 28. This is thanks to the increased tension and strength by using straight pull spokes (vs a J-Bend)"

Pretty sure j-bend is almost never the weak point re: high tension. A spoke hole is going to give long before either a J or a straight spoke breaks at the head, leading to another spoke breaking, and usually at the threads, which is the same for both straights and Js.

 Nothing better than trying to true a wheel with round straight pull spokes after it's been ridden a few seasons

 Grip the spoke with Knipex pliers as you spin the spoke wrench. NBD, done it plenty of times. You get in a rhythm and it goes pretty quick.

 @rickybobby19: If only there was a style of straight pull spoke that didn't require a hack to tension. Like maybe a flat surface where you can fit a tool to prevent rotation.

 Perhaps it is a good set of wheels, but since it is more expensive than my Hope/EX471 I will never try it. Alloy reserve wheels bring the lifetime warranty argument to make me think about it, here nothing like that…

 The trendy lack of vowels in their little "HZN" abbreviation thing really sparks a seed of rage within me. That being said, Nukeproof stuff is almost always an excellent value proposition. I run their jerseys, ARD inserts, stem, seat clamp, downhill pedals, and carbon bars. No complaints with any of it.

 I’ve had the v2 wheelset mostly on a hardtail for two years but I switch off with the full suspension. They’re absolutely bombproof. I haven’t touched the bearings and can’t even see signs of dirt or water getting in and my east coast trails are filled with dirt, mud and stream crossings. I’d rate the hubs above my 101s, which are also fantastic hubs. The only con was the V2s were a tad heavy. But I’ll gladly take that considering how durable and compliant they are. Seems like the pros fix the weight issue.

 Looks good but the spoke selection is unimaginative. There are some models from Pillar that are the same weight as the Sapim Race but in bladed form for easier truing.

 Not a bad setup. Straight pull are a bit of a pain, but in a 28h setup, would be as compliant as a 32h j-bend. As long as the rim is decent. Wonder if they licensed the 54t ratchet from DT? Think the 90's hubs used Shimano's freehub, so replacements were easier to come by. It's not a bad practice, licensing things that work and you can find replacement parts for and buy, bike part makers of the world, take note.

 Article claims they are double butted straight pull spokes. Dimensions are 2 - 1.8 - 2 - finding that EXACT size in proper length may be a pain. I think most good shops would stock them, but not as common as a J bend spoke.
