Ready to race.
With the dust settling from the most recent flurry of new axle standards, Boost spacing seems to be the agreed upon option for increased stiffness and responsive handling. With its Crossmax Pro WTS 27.5in Boost Wheel, Mavic ensures your new Boost-equipped CX frame benefits from the company's legendary ability to produce fast, snappy, and nearly bombproof wheels.
The main feature setting the Pro apart from the rest of the Crossmax line is the inclusion of Zicral spokes. Most spokes of the knobby tire persuasion are steel, which is reliable but heavy and fairly elastic. Zicral is Mavic's secret weapon, and it plays a large role in shaping the Pro's trail presence. Stiffer, lighter, and stronger than steel, Zicral represents Mavic's road-race A game adapted for the XC world. The trade-off is a slightly harsher ride, which is balanced out with lower-than-clincher tubeless PSIs providing a bit of extra cushion.
Mavic's Inter Spoke Milling 4 Dimensions (ISM 4D) process is the newest version of its signature rim milling process. ISM involves removing unnecessary rim material to eliminate grams and reduce rotational mass along the wheel's circumference. The OG ISM limited milling to the rim's inner face. It's successor, ISM 3D, expanded its attention to the sidewalls, and ISM 4D takes things a step further, smoothing the rim's transitional angles to further reduce weight without sacrificing strength..
While Mavic's ISM 4D keeps rotating weight low, the Instant Transfer System 4 (ITS-4) rear hub ensures that efficiency isn't wasted by sluggish, unresponsive engagement. IST-4 is a four pawl system that alternates engagement between two pairs of pawls. Since both pairs engage at different points in the freehub's rotation, the gap between engagement points falls to just 7.5 degrees of free play. The sharp engagement angle is further complemented by the stiff, 17mm monoblonc axle, which tapers down to 12mm to take advantage of the new, more efficient standard of oversized dropouts.
The Crossmax Pro's rims incorporate Universal Standard Tubeless (UST) design, which eliminates tubes and tape when running tubeless with Mavic's UST tires and is compatible with nearly all tubeless and clincher tires. It comes outfitted with Mavic's own Pulse Pro tires, featuring a dual compound designed to match well with the Crossmax Pro's XC and light trail preferences.
