I splurged on a set of Mavic Crossmaxes in the early 2000s, and they completely changed my perception of mountain bike wheels — forever. Now, twenty-plus years later, Mavic is launching the lightest Crossmax ever built, made to perform at the highest levels of cross-country mountain bike racing. They officially debuted at the Les Gets World Cup XC this weekend, raced by the Mavic-sponsored Mondraker and KTM Factory XC Teams. 

Designed with input from athletes and validated/tested on the World Cup XC circuit, Mavic says its new wheels are engineered to make you faster. With a claimed weight of just 1080 grams/pair, the Crossmax Ultimate wheels promise “to deliver explosive acceleration, razor-sharp handling, and podium-worthy performance.” Let’s check them out.

Mavic Crossmax Ultimate Details

The new Crossmax Ultimate is aimed squarely at cross-country racers, including those competing at the very highest level of the sport. Mavic states that these wheels were developed with and for professional XC racers to deliver uncompromising performance at a very light weight.

How light? Mavic claims the new Crossmax Ultimate wheels weigh just 1,080 grams for the pair with an XD freehub and rim tape. How did they get it so light? According to Mavic, “Every gram, every fiber, and every component has been challenged in the pursuit of pure XC performance.” This includes a new rim concept, carbon spokes with titanium nipples, and new UltraLight Hubs, each of which reportedly reduces the wheelset weight by 100 grams, or 300 grams total.

Adaptive Layup Carbon Rims

At the rim, Mavic says that its new Adaptive Layup optimizes the carbon fiber layers to achieve the optimal balance of stiffness, vibration damping, and low weight. The rims have a 25 mm depth and 30 mm internal width to support modern XC tires. Each rim is drilled with 20 holes with an unspecified offset to optimize spoke loading on the drive side (rear) and braking side (front).

UltraLight Hubs

At the center of the Crossmax Ultimate wheels are Mavic’s new UltraLight Hubs. According to the brand, these hubs weigh just 105 g/180 g for the front/rear, respectively, in the XD 6-bolt configuration. They spin on Mavic’s precise, low-friction ceramic bearings, feature the 40-tooth ID360 LIGHT ratchet for quick engagement, and an optimized spring to minimize freewheel friction. 

Carbon Spokes

Mavic opted for a 20-spoke count in a 2-cross pattern front and rear with straight-pull carbon spokes that combine an “optimized stiffness to weight ratio” with “natural vibration damping properties.” They chose titanium nipples to reduce rotational weight even further, so every precious watt is transferred into forward motion.

Validation

In addition to field testing, Mavic says it performed 57 different tests on its in-house machines to ensure performance and reliability. On top of that, the Crossmax Ultimate wheels have been in use by the Mondraker and KTM Factory XC teams since the beginning of the 2026 season. In that time, these wheels have helped propel Katrin Embacher to a U23 XCO victory, along with multiple top-10 Elite performances.

Really happy to see Mavic bringing top of the line in all ranges, from the Cosmic Ultimate, and the Comete on the road and this one here, looking forward for some lab tests!

Modern XC wheels have gotten significantly wider than just a few years ago. I currently ride an XC bike with wheels that have a 25mm internal width. I’m running 2.35mm tires but have also 2.4mm tires on those same rims.

For those who have ridden wider rims, is it worth it to either upgrade my wheels or potentially re-lace them to wider rims?

In general, the wider rim allows for slightly lower pressure for a smoother, faster ride, without worrying about tire “squirm” when railing corners. Plenty of arguing can be found about this on the internet.

For most riders, yes. For a given pressure, wider rims produce less lateral deflection and raise the amount of lateral force required for tire collapse. This will allow you to lower your pressure while maintaining lateral stability.

One possible exception is if you already get pinch flats – or know you would if you lowered your pressure even slightly – yet don’t experience lateral instability. If this is the case, I recommend wider tires (ex. Maxxis Rekon 2.6″ – an outstanding and often overlooked tire) on wider rims if your frame has sufficient clearance; if not, stick with your current set-up.
