The Hunt XC Wide wheelset is aimed at cross-country riders who want to get rowdy on the downhills. As a new breed of slacker, 100 to 130mm travel downcountry bikes become more popular, riders are beginning to look for wheels that are not only spritely on the climbs but have a wider and more robust rim profile that can handle increasingly challenging terrain.

Hunt seems to offer an almost complete wheel package. Durable 6061 T6 alloy rims give superb support to tires between 2.1- and 2.5-in to maximize traction when climbing and in corners. The hubs have a snappy five-degree engagement and are available in boost or standard spacing.  It might not be the lightest wheelset but for a bit more money, Hunt sells a Race version that proves alloy isn't dead, weighing in at a claimed 1,517g.

The Reserve 28XC are World Cup winning wheels and are a race-ready culmination of everything the brand has learnt from years at the highest levels of competition. 

At 1387g for a complete DT Swiss 180 hub wheelset with tape and valves (AND no rider weight limit and lifetime warranty), the 28XC features a wider and lower rim profile than their previous XC race wheels, that increases strength and lateral rigidity while adding vertical compliance. 

The new rim shape also eases tubeless tire installation and improves tire bead retention at lower pressure. The Reserve 28XC is sturdy and strong enough for a rowdy XC ride, but light and fast enough for a jaunt on the World Cup XC circuit.

The wheels may not be the lightest, but their weight is extremely respectable. The lightest option weighs in at a race-ready 1387g while the cheaper DT Swiss 350-hubbed wheelset still only adds on 183g with a saving of $600.

Reserve gives the option to spec three different DT Swiss hub options, the 250, 240 or 180. As always, DT hubs offer excellent durability and simple tool-free servicing. The rims and hubs are also backed up by a superb warranty so you can ride hard mile after mile.

These custom carbon gravel and XC wheels are hand-built in Yorkshire, England. Weighing just 1,350g for the pair, the Just Riding Along Monitor is incredibly lightweight yet surprisingly robust. Since they're a custom build, you can choose to have them exactly how you want, with a tougher bikepacking version also available.

Choose between 650b or 29er rims, 24 or 28 holes, J-bend or straight-pull spokes, and Centerlock or 6-bolt disc hubs. You can decide the spoke count, the freehub, opt for boost spacing and choose custom colors for the nipples and decals. Finally, you can add on optional tubeless valves.

Whatever you opt for, the super low weight of these wheels will give your ride an instant boost in acceleration, while the freehub's fast engagement helps pedal strokes feel responsive. After several months of punishing them off-road, exposing them to cobbles, mud and grit, they held up exceptionally well and we've had no issues.

Crankbrothers has tuned its Synthesis wheelset to achieve a difference in ride quality and lateral flexibility between the front and rear by using different rim profiles and spoke counts.

The Synthesis front wheel only has 28 spokes, while the rear is laced with 32. Internal rim widths differ too: they are wider at the front than the rear. Crankbrothers believes that a front-wheel should be more forgiving, as it is responsible for turning the bike and experiences severe terrain deflections that could ruin steering feedback dynamics.

Crankbrothers offers three different alloy Synthesis wheelsets, with its front/rear-specific build. The brand’s Synthesis XCT is a lightweight 29-inch option, featuring a 24.5mm internal diameter rear wheel and 26.5mm internal diameter front, the total weight of which tallies 1,554g.

Mavic started making bike rims 130 years ago and it's been refining its tubeless rims for over 20 years. The CrossMax XL S rims are engineered with Mavic patented Fore technology, featuring a fully sealed upper bridge that eliminates the need for rim tape. That saves 30 grams per wheel and does away with the hassle of using tape to set up tubeless tires. 

They also use ISM rim machining, which removes material in strategic areas of the rim to minimize weight without compromising strength. The rim has a 30mm internal width, optimized to squeeze the best performance out of any modern tire, and the Mavic Black Shield technology gives them distinctive finish that protects against scratches and abrasions. You can also swap the reflective logo stickers for custom bi-color logos from Silk graphics.

With 24 straight-pull spokes to further dial in the sweet spot between lateral stiffness and vertical compliance. The Infinity hubs feature a stiffer and lighter construction that is enhanced by the ultra-reliable ID360 double ratchet system for fast engagement. 

The wheelset is set up for 6-bolt or center lock disc mounts and is compatible with Shimano HG9, SRAM XD, and Micro Spline freewheel bodies. It’s available in 29” only and ships with UST tubeless valves, spare spokes and accessories.

Cutting edge carbon rim technology meets the ground breaking Hydra hub platform to create some of the highest quality and best performing wheels on the market.

The carbon rims are produced in partnership with Canadian carbon company We Are One Composites who use the latest carbon layup technology. Each rim is hand laid in Kamloops BC to Industry Nines exclusive layup, mold and performance specifications.

Depending on your weight and riding style, the Industry Nine Enduro wheels are available in 27.5-inch or 29er versions and with 24 or 32 spoke designs, can be purchased as a complete build or customized using various components. The Ano Lab Custom Color gives you the pick of 11 different anodized colors to create a look as colorful or stealth as you wish making for an impressive and unique to each rider wheelset.

They also employ a hookless system for impact resistance, a 31mm internal rim width and have a limited lifetime warranty for peace of mind. The rim is designed to accommodate 2.3- to 2.8-inch tires

A big drawcard with these particular wheels is the Hydra freehub – offering 690 points of engagement, power delivery is immediate.

Enduro 315 Carbon 24h Rims are currently on backorder so you may have to wait to ride these beauties.

We were big fans of Hunt's original Trail Wide wheels, and the new Hunt Trail Wide wheelset provides the same great performance. They feature a bit burly build with more metal, which makes them heavier and a bit slower to get up to speed, but they are still faster and lighter than their closest competition.  

When the going gets rough, the Trail Wide's act smooth and connected, meaning that they give good trail feedback to the rider, provide needed traction, and remain composed in corners. Fans of rough trails will be happy with the durability of the wheels too since we haven't managed to dent them yet. Overall, these put more expensive wheelsets to shame, making them an excellent budget upgrade option.

These carbon wheels from Syntace are great value for money, offering standout, responsive and hyper-accurate performance for a fair price. The build quality is exceptional, with a triple sealing and reinforced freehub and bearings for extra durability.

They're available in 26-, 27.5- and 29-inch diameters with a choice of 28, 33 or 40mm internal rim widths. Pair these with rubber between 2.3- and 2.6-inches for an incredibly stable and supple ride feel. The carbon rims use various composite weaves, including cross-ply in the sidewalls for damage control.

It's no surprise seeing this kind of performance from Syntace, which was one of the first wheel brands to produce extra-wide rims. Pioneering fat tires for extra-stability, the brand offers 80 wheel choices when you count all the different options available. It's fair to say it knows a thing or two.

Compliance can translate to vagueness on flat-out bike park berms

Wheel manufacturers are now understanding that despite a stiff wheel giving sharp cornering and acceleration, building compliance into a wheel allows better grip and control as the wheel can deform over rough terrain. 

No manufacturer takes the concept of wheel compliance further than Zipp which has entered the mountain bike market for the first time with its 3Zero Moto wheelset. Inspired by the single wall rim designs in motocross, the 3Zero features a 30mm internal width and can be purchased as single wheels or as a wheelset, in both cases built around Zipp's ZM1 hubs with standard splined SRAM/Shimano or SRAM XD freehubs. 

Wheelsets come as boost only in both 27.5- or 29-inch formats. If you purchase the complete wheelset, Zipp includes the Tyrewiz pressure gauges to make sure you're always at the preferred PSI for optimal grip.

The Swiss brand says that its DT Swiss XM 1700 wheelset are the wheels that hardcore riders would build for themselves. We found that that's mostly the case with these aluminum all-mountain hoops. 

For added toughness, DT Swiss has added more material on the sidewalls and bottom of the rim. The tough design does come with a weight penalty though. The wheels have an accurate, stiff feeling that precise riders will love. 

The main advantages we see with these wheels are the durability and the price point. If you're sick of constantly truing wheels and don't have a lot of cash to spend on a carbon pair of hoops, these are a good choice. 

Read our full DT Swiss XM 1700 review to find out why they are one of the best new all-around wheels we've tested.

Santa Cruz’s Reserve DH 29er wheels are downhill-specific carbon hoops designed to withstand the abuse and impacts of modern downhill courses. 

The company has after all forged a name in the industry for pushing the boundaries and debunking the myths associated with carbon fiber, most notably on its bicycle frames.

Available in two wheel sizes, three hub choices and several rim widths, the Reserve 29er wheels are built with J-bend spokes with external secure-lock nipples for better consistency in terms of strength and durability – both front and rear wheels use a 28h spoke pattern.

Despite its downhill bent, the Reserve DH rim profile features a combination of stiffness and compliance. Add to that an asymmetric rim design and offset drilling pattern, both of which promote an even spoke tension, and the Reserve might just be the most balanced carbon downhill wheel ever made.

The Hope Fortus SC 30 is one of the most affordable downhill wheel options currently on the market. Like its chief adversary, the Nukeproof Horizon, it’s built from aluminum and threaded to Hope Pro 4 hubs with Sapim Race stainless steel double-butted spokes and brass nipples.

While these additions have significantly strengthened and stiffened the wheel - at both the front and rear end - they’ve also pushed up the weight to 2,435g (set of 29er wheels), which is notably heavier than other wheelsets of the same price point and ilk.

As their name references, the Fortus 30 wheels have an internal rim width of 30mm ensuring the tire is the perfect shape to give riders optimum grip in high-speed cornering situations.

Best mountain bike wheels: what you need to know

What material is best for wheels?

Mountain bike wheels are manufactured from either carbon fiber or aluminum, both of which have their own pros and cons. Carbon wheels are stiff, light, strong and also absorb trail buzz to a certain extent but they’re expensive. Aluminum on the other hand is a lot cheaper and, while it also delivers a fairly decent amount of stiffness and performance, rims are prone to flex and dents but can be trued and repaired — carbon not so much.

How wide should MTB wheel rims be?

Rim width has become a hotly debated topic over the years in all forms of cycling, owing to the lower rolling resistance and better grip offered by fitting larger-volume mountain bike tires. The important factor to note here is internal rim width which dictates what tires you can safely use — as a rule of thumb, the wider the rim, the greater the tire volume and contact patch with the trail. Rim widths differ vastly between cross-country, downhill and enduro wheels with profiles ranging from 23mm to 35mm.

How many spokes is best for MTB?

In a nutshell, spokes connect the hub to the rim and give the wheel its strength and shape. Spoke counts can differ between the front and rear wheel and the latter often employs more spokes for added strength and stiffness. Lacing patterns also vary and have different properties — some wheels are laced with two-cross straight-pull spokes for weight reduction (cross-country) while others employ three-cross-lacing patterns for better strength and torque efficacy (downhill/enduro). Spokes are made from either steel or aluminum and sometimes even carbon fiber.

What should I know about hubs and axles?

The best mountain bike hubs are constructed from aluminum or carbon composite. While the front hub is simple in function, the rear is more complex, featuring a freehub body onto which the cassette attaches. It also houses the intricate spring-loaded ratchet-and-pawl mechanism which enables the wheel to spin when freewheeling and engage the transmission when pedaling. Bigger pawls will deal better with more torque (downhill/enduro) while on the opposite end finer pawls will result in a faster engagement and better power delivery (cross-country).

Some freehubs, like those from DT Swiss and Chris King use a ratchet system rather than pawls, which provides more simultaneous points of engagement.

The need to continually improve front and rear-end stiffness has led to the introduction of thicker, more stable thru-axles that bolt directly into the fork and drop-outs. Most newer bikes offer wider ‘Boost’ axle spacing, which uses a 110x15mm front axle with a 148x12mm rear thru-axle for added levels of stiffness.
