Looking for the best mountain bike wheels for your ride? We've purchased and tested dozens of wheelsets over the past several years, and these are the most compelling options we've found through our rigorous testing and comparison process. Wheels dramatically affect ride quality, and upgrading the stock wheels on your bike can seriously improve the overall performance and handling. With so many options on the market today, deciding on a new set of wheels can be overwhelming. This review focuses on the carbon and alloy wheelsets we found most worthy of your consideration. We found ugly lines, brutal climbs, and big hits to put them to the test. Over dirt, sandstone, granite, and gravel, we found berms, jumps, rock gardens, and technical lines to parse out the differences so you can find what best fits your riding style and budget.

RaceFace hits a home run with the ERA wheelset, they're compliant without feeling flexy, relatively lightweight and priced incredibly well for the level of performance they provide
We're wildly impressed by the RaceFace ERA Wheelset and feel they're the best wheel upgrade for most trail and enduro riders. These wheels use optimized rim profiles to provide lateral compliance in the front and impact protection in the rear. The ERA rims have a 30mm internal width, Anvil-edge bead walls, and 4mm of spoke offset. Using RaceFace's own Vault hubs, the oversized shells provide a wide bracing angle to increase torsional stiffness and balance spoke tension. Twenty-eight double-butted direct pull spokes are laced 3x but don't touch.
The wheels feel snappy and light but provide more dampening than most. As you'll read in our full review, “What really stood out with the ERAs is how much the wheels increased my control without ever feeling soft.” Carbon can sometimes feel harsh or too rigid, but these wheels cheated lines like the Zipp 3Zero Moto without the weight penalty. Considering their price and lifetime warranty, which includes crash damage, we wholeheartedly recommend them.
We scratched our heads to come up with negative things to say about these wheels, but that's what reviews should do, so here. The ERA Wheelset could be lighter, but 1769 grams for an enduro-approved wheelset is far from heavy; they're the third lightest wheelset in our test. The graphics on the rims are somewhat loud, but they're easily removable. The Vaults 60-tooth drive ring provides 3-degree engagement, which is usually something to brag about, but we're stacking them up against the Industry Nine Solix wheels that engage 5x faster. How much engagement speed matters is a hotly debated topic, but the ERA wheels never felt slow.
The Industry Nine Solix M TR300/290 isn't just a compilation of high-quality components. This wheel system is produced entirely by Industry Nine, giving them precise control over exactly how strong, compliant, and lightweight these wheels are. While many high-end wheels on the market today use Industry Nine hubs, the Solix wheelset capitalizes on the integration of hub, spoke, and rim; there are no compromises. Using carbon rims specifically designed for front and rear use, I9 brings us compliance up front and solid durability in the rear. Our testers loved the feel of these wheels; they are spry and responsive without sacrificing compliance. 605 points of engagement eliminate backlash and give the wheels incredibly quick acceleration. I9's direct pull aluminum spokes forego nipples and thread into the hub shell, saving valuable rotational weight.
These spectacular wheels don't come cheap, but industry-leading technology and American manufacturing aren't usually synonymous with low prices. The large price tag gets you incredible performance, a lifetime warranty, and your choice of twelve custom anodized colors. They have subtle decals but also look great with the decals removed. These carbon wheels impressed us on every level; their performance absolutely floors us.
Our testers were thrilled with the performance of the Industry Nine Enduro S Hydra wheels. These are easily the best alloy wheels we've ever ridden, and they gave the more expensive carbon competition a run for their money. While fairly lightweight, they don't compare to our lighter carbon offerings. They have a nicely balanced ride quality that is an excellent blend of agility and comfort. Just looking at the wheels, you can see the craftsmanship of the finely machined hubs and extruded rims; the engineering and tolerances of the Hydra hubs are groundbreaking. The freehub engagement is the real highlight, and Industry Nine has given these wheels an astounding 690 engagement points, or 0.52 degrees. This engagement is far superior to any other design we've tested, giving them a super quick, lively, and high-performance feel.
Though we might consider giving up our carbon wheels for the Enduro S Hydra, these still can't quite compete with carbon in the weight department. They are the lightest alloy wheels we tested, but they carry a little more rotational mass than their carbon competitors, and they're not nearly as durable. They're also not cheap; they are the most expensive alloy model we tested. We'd still recommend these wheels to any light-on-their-wheels rider seeking a major performance upgrade who doesn't want to shell out the cash for carbon hoops.
In one sentence, these wheels offer insanely good performance for the price. They're one of the best no-nonsense alloy wheelsets we've tested; the Hunt Trail Wide MTB delivers on performance, weight, and value. These sensibly priced wheels perform far beyond what their price might suggest. Starting with the rims, Hunt gives us the 30mm internal width and pinch flat resistance we desire from their H-lock bead system. The rims have laser-etched graphics over a work-hardened and shot-peened surface, providing durability and great looks. The rims are laced with 28 triple-butted spokes that keep the weight down and give them a spry, energetic feel. The hubs are full of features, including a forged front hub and oversized 7000 series axles and Torque Caps if so desired. All of the options are available with their hubs, 142, boost, or super-boost spacing, HG, MicroSpline or Sram Xd freehubs, and 6-bolt or Centerlock rotor mounts. Engagement comes at 5 degrees thanks to a “RapidEngage” freehub that uses three sets of 2 pawls paired to a 36-tooth drive ring. The exterior of the freehub body is coated with a proprietary H_CERAMIK reinforced coating that prevents cassette damage. The wheels arrive with installed tubeless tape and valves and weigh only 1869 grams.
While the 5-degree freehub engagement is not the most impressive, it feels respectable at this price. The engagement also didn't seem to have a huge impact on their performance, as they were quick to ratchet and accelerate. The front wheel could feel somewhat flexy under load, but that can also be interpreted as comfort, and we were pleased with the balance of performance and compliance. Our minor concerns didn't feel significant, considering the price and level of workmanship. If you want a meaningful upgrade without breaking the bank, Hunt is a great place to start.
The Zipp 3Zero Moto wheels are the first real mountain bike wheelset from Zipp, and they propose a new way forward. The moto-inspired single-wall carbon rim features ankle compliance to increase traction and deflect direct hits. These wheels tap into a different aspect of the carbon performance advantage and give the bike a unique calm and composed feel that is unique in the mountain bike wheels market. The rim's ability to flex laterally results in impressive cornering traction and the muting of feedback over rough and chunky terrain. The ZM2 hubs are solid, with 2.7 degrees of engagement and a refined appearance, but they get overshadowed by the rim technology. Zipp is also so confident in the durability of their wheels that they offer a lifetime warranty that reads, “If it happens while riding, it's covered.” Those looking for a snappy, lightweight set of carbon wheels might want to keep looking, but if downhill performance, traction, and comfort are your guiding metrics, these wheels feel unrivaled.
We are disappointed these wheels aren't offered with a Shimano MicroSpline freehub body. We have come to expect a light and snappy feel with carbon wheels, and while this is less prevalent with this model, the performance advantage provided by their compliance was undeniable. Sometimes, feeling a tad sluggish on the climbs and slower to accelerate, we certainly weren't always keen on the extra weight. What these wheels lacked in zippiness, they more than made up for in control and traction.
Long-term thoughts: Having spent the better part of two years on these wheels, they feel as revolutionary (no pun intended) as the day we first rode them. We've put them on over a dozen bikes and felt the massive difference they make to compliance and control. We really hope Zipp will continue to develop this technology, maybe even offering a lighter set in the future.
Zipp backs up their bold claims with wheels that perform as advertised. Smooth and damp with loads of traction thanks to the moto-inspired single-wall design.

How We Test Mountain Bike Wheels
After spending hours researching the best mountain bike wheels on the market, our team purchased nine models to test and compare side-by-side. Our selection of all-mountain/trail wheelsets includes six carbon and three alloy models representing a large price and performance range. Once in our hands, each wheelset was weighed, measured, and photographed in new condition before being mounted with matching tires. The wheels were then passed between testers who used each set on their personal bikes for familiarity and consistency. Each pair was ridden hundreds of miles on the vast and varied trails of the northern Sierra and the greater Lake Tahoe area. Shuttle runs, all-day backcountry epics, races — our testers did everything on these wheels, riding them harder than if they were their own. Our testers took detailed notes on each model, and when our test period ended, we rated and ranked them on several performance metrics. For more about our testing process, see our How We Test article.

Analysis and Test Results
Over several months, our professional mountain bike testers pedaled their hearts out, putting each of these wheelsets through their paces to find the best wheels for every rider. We put hundreds of miles on each pair, scrutinizing every aspect of their design and performance. We focused on each wheelset's ride quality, freehub engagement, weight, and durability. Then, we compared notes and tallied scores to determine our award winners.
What's the Best Value?
The most expensive (read: carbon) wheelsets were also the highest-rated. The Hunt Trail Wide V2 is one of the least expensive models in the test, yet it scores relatively well from a performance standpoint. Our testers were also very impressed with the Raceface ERA wheels. These were not the most expensive wheels we tested, but they had the performance metrics that impressed us the most.
It is important to note that some wheelsets are sold as pairs while other manufacturers and online retailers sell their wheels as singles, either front or rear. For the latter, the price of a complete wheelset will be significantly higher, double or slightly more, than the price of a single wheel.

There is more to consider when assessing the value of a product than just its specifications and price. Nowadays, it is becoming increasingly common for companies to offer lifetime warranties with their carbon wheels, which adds significant value. For example, the Santa Cruz Reserve 30 Carbon Wheelset, the Zipp 3Zero Moto, and the Industry Nine Solix M TR 300/290all come with impressive lifetime warranties. These warranties go beyond just defects in materials and workmanship; they promise to repair or replace your wheels if they get damaged while riding. This is an exceptional value-add for an expensive purchase, guaranteeing that you will be able to use your wheels for many years to come.
The Enve AM30 wheels, on the other hand, come with a five-year warranty against defects and “incident protection,” which is essentially a discount that can be applied to the purchase of new wheels should they become damaged. Similarly, Stan's and Hunt offer crash replacement discounts in addition to a standard warranty against defects in materials or workmanship. While we appreciate warranties of all types, the reality of incident protection or crash replacement policies is that you will likely have to spend hundreds of dollars out of pocket if you damage your wheels, ultimately affecting our perception of value.
Overall, the durability of carbon wheelsets surpasses that of alloy wheels and contributes to better value in some of the higher-priced models, especially those with lifetime warranties.

Freehub engagement is a performance metric that affects how we value these wheels. A faster, more responsive hub is perceived as more valuable as it allows for more responsive acceleration. The Stans Flow Mk4 wheels come standard with a 1.66-degree freehub engagement, and the Industry Nine Enduro S wheels boast a .52-degree engagement. This excellent performance warrants some extra dollars, which is why these alloy wheelsets are scratching the surface of carbon wheelset prices. On some hubs, the freehub can be upgraded for faster engagement; the Santa Cruz Reserve 30 Carbon wheels, for instance, come with a lackluster 10-degree engagement but can be upgraded to 6.6 degrees. The $50 ratchet upgrade will enhance performance, but it eats into the value proposition of that wheelset.

Ride Quality
Our testers identified the specific performance characteristics of each wheelset's ride quality. The differences are often subtle, and differentiating between them can be challenging. By riding our test wheels back to back for comparison, we discerned the nuanced differences that give each model its distinctive ride quality.
It's no surprise that carbon wheels feel quite different from alloy models. Carbon wheels are known for their stiffness, precision, and lightweight. Carbon also has had a reputation for being stiff to the point of harshness, causing deflection and giving excessive trail feedback. The new generation of carbon wheels has worked to change that reputation with models that have a little more compliance and dampening engineered to produce a more balanced ride. These wheels are generally lightweight and durable, with the efficiency and precise handling you want, plus enough give and vibration absorption to enhance their comfort on the trail. On one end of the spectrum, we felt the Enve AM30 was a little too stiff and transmitted unwanted feedback to the rider. On the other end, the Zipp 3Zeromoto produced such a muted experience that the bike felt like it had additional travel. The Industry Nine Solix M TR 300/290 and Santa Cruz Reserve Carbon 30 achieved solid middle ground, producing a stiff and light-feeling wheel that never felt too harsh.

Alloy wheels are generally more flexible and compliant compared to carbon. They traditionally have had a more forgiving ride, but as a result, sacrificed some precision and efficiency. Some riders prefer the feel of alloy wheels because of their forgiveness and lower price point, even if they are a bit heavier. Of all the alloy wheelsets we tested, the Industry Nine Enduro S Hydra was the tester's favorite. These wheels felt stiff and nimble but also balanced and compliant. The weights of all of the alloy contenders were pretty similar, but the Hydra freehub was the fastest freehub by far. The Stan's Flow MK4 also impressed our testers with a lively and responsive ride blended with a bit of forgiveness.

Freehub Engagement
Freehubs are designed in a variety of ways, but they all allow the hub to spin freely when coasting and to grab, or engage when the pedals are turning. All the freehubs in this test have some lag between engagement points, which creates a dead spot in the pedal stroke before everything reengages. The distance between engagement points is calculated in degrees; freehubs with fewer degrees feel higher performance because there is less lag in the drivetrain system.
Industry Nine has been a market leader in freehub engagement, and they raised the bar when they introduced their Hydra hubs. The Hydra hubs on the Enduro S wheels have the fastest engagement we've ever used, with just 0.52 degrees between engagement points. It is truly next level, and they can be purchased and configured on a huge range of aftermarket wheelsets. The I9 Solix hubs use a 5-pawl system instead of the 6-pawl system used on the Hydra hub and achieve 0.59-degree engagement with a touch less drag. Stan's Flow MK4 use a slightly different strategy to achieve 1.66-degree engagement from their M-pulse hubs. While most freehub pawls are pushed outward into the hub using springs, the M-pulse hubs use magnetic pull force to engage the pawls, a system that Stan's claims reduces friction while coasting. The noise we hear when coasting is the pawls pushing against the drive ring, and noise equals friction. We couldn't quantify the reduced drag from the M-pulse hubs, but they do coast freely and feel efficient.
Zipp uses a dual ratchet ring and 12 pawls (4 groups of 3) to achieve 132 points of engagement or 2.7 degrees which feels solid and quick to engage. Building a faster hub requires more accurate machining and tighter tolerances, which results in increased performance but also increased cost. Is rapid engagement worth the cost? For riders who enjoy quick starts and ratcheting through technical terrain, you might find value here. A slower freehub results in more play at the pedal and a delay in power being transmitted to the ground. If you've never noticed that delay or don't mind it, you might be able to save some money on your next wheelset. Ten degrees of engagement is relatively standard but feels lackluster on an aftermarket wheelset.

Weight
We weighed each pair of wheels as they'd be ridden, including tubeless rim tape and tubeless valve stems. In general, we feel that less weight is better as long as the wheels still perform as intended and don't sacrifice durability. Weight is particularly important in a pair of wheels since they're rotating. More rotational weight at the rim can have the adverse effect of making your bike feel lethargic and slow. The lighter your wheels are, the lighter your bike feels, the easier it climbs, and the faster you can accelerate. All other things being equal, lighter is better, although it often comes at a price. All of the wheels we tested were 29 inches in diameter with standard Boost 148 spacing and 15x110 front hubs.
Not surprisingly, most of the carbon models we tested weighed less than their alloy counterparts. The lightest wheelset in the test is the Industry Nine Solix M TR300/290 at an impressive 1,475 grams, while the heaviest was the Zipp 3Zero Moto with an over 500-gram difference. Judging by weight alone, the Zipp wheels wouldn't really be contenders. While they did ride with many of the negative characteristics we attribute to heavy wheels, they will find a fan base willing to overlook weight for their unique ride quality. The Hunt Trail Wide V2 wheelset weighed in at 1869g. and embodied much of what we enjoy in a lightweight wheelset. They spun up fast, felt nimble and responsive, and made our test bikes feel more agile.
In general, an aluminum rim is heavier than a carbon fiber rim, and it's also much less expensive, so it stands to reason that most of the alloy-rimmed wheels we tested weigh more and cost less than their carbon competition. Of all the alloy wheelsets, the Hunt Trail Wide V2 was the lightest at 1,869 grams, followed very closely by the Industry Nine Hydra Enduro S at 1,895 grams and the Stan's Flow MK4 at 1919 grams.

Durability
When shelling out your hard-earned cash to upgrade your wheels, it's nice to think they'll last a while. No set of mountain bike wheels will last forever, but most should provide you with several years of trouble-free use. Carbon wheels, once considered a risky purchase, now hold a reputation for durability. Unlike alloy rims, carbon hoops can absorb impacts and deform without being permanently damaged. While the initial cost is more expensive, the long-term durability may give them a price per mile less than their alloy counterparts.
Many people will choose alloy wheels due to their affordability. The initial price is lower, and repairing or replacing them is significantly less expensive. The price of carbon wheels has steadily been getting closer to alloy for years now, so there may be a shift happening as more riders realize the benefits of carbon, especially when backed with impressive warranties.
To test each wheelset's durability, each of our testers rode them in their own style. Some of us plow through rock gardens, some of us approach them with a little more finesse, and some of us fall somewhere in between. All of us put a lot of miles and some serious abuse on every set of wheels in this test. We played around with tire pressures and definitely rimmed out on every rear wheel several times in the name of testing. While the wheels weren't unscathed, none of them required more than a few turns of a spoke wrench. There were no broken spokes, dented or cracked rims, or damaged bearings.
Afraid carbon wheels aren't durable? You can put those fears to rest thanks to the new breed of super durable carbon wheels with excellent warranties.

Carbon wheels have proved themselves to be more durable than alloy; because of this, we rated the durability of each carbon model slightly higher than the alloy models. Wheels with better (lifetime) warranties also fared better.
