The Mavic Crossmax ST Disc Wheelset sits attractively in the middle of their line-up as the wheelset that seems to be ready for it all. Racing cross-country this weekend, getting rowdy on some technical trails the next? These wheels are reasonably light and ultra-reliable so they can handle either without being a detriment in any way. And it’s their adaptability along with the clean aesthetic that makes them our favorite Mavic MTB wheels. Mavic builds them this year with a new rim extrusion that shaves 35 grams out of the wheelset, though the strength is still exactly the same.
The Maxtal rims are part of why the Crossmax ST Wheels are so tough. The proprietary Mavic alloy is 30% stiffer than typical 6106 alloys. And they’re made a bit wider than traditional MTB rims, 19mm on the inside, in order to allow a fuller spread for the tire carcass. This improves trail grip, adds stability to the sidewall for wicked fast cornering, and reduces chances of pinch flats if you’re using tubes. Mavic’s SUP process creates the welded rim joint and machined sidewalls. The next step relieves the rims of excess material between the spoke holes. This is another machine process, known as Inter Spoke Milling (ISM), and it helps shave precious grams from the rims. Finally, the rims are shot-peened to increase surface hardness and strength.
One of the key features of the Crossmax line of wheels is that they’re UST certified for tubeless applications, and we’ve found nothing that offers performance as good as true UST rims. Mavic achieves this capability by using their Fore drilling process to eliminate spokes holes in the rim. Only the inside wall of the rim is pierced for the spokes. The outside wall has only the valve stem hole, and it’s sealed to perfection with the included UST valve stems.
The Crossmax ST Disc Wheels employ 24 straight-pull Zicral aluminum spokes in the front wheel and 20 in the rear wheel. The front wheel is laced in a standard 2-cross pattern. The rear is a bit more complicated; the Isopulse lacing (2-cross on the left and radial on the right) gives more balanced spoke tension and better durability. The snow white hubs and the axles inside are made of aluminum, and their micro-adjustable design ensures a perfect preload and smooth operation of their QRM+ sealed cartridge bearings. The wheels include the bearing adjustment tool/tire lever. The ITS-4 freehub body is new to the Crossmax ST wheels. It’s compatible with 8-, 9-, and 10-speed MTB cassettes, and it’s more durable than the previous FTS freehub body. It also offers less freeplay (7.5°) between engagement points for quicker and more efficient energy transmission.
This wheelset is part of Mavic's MP3 extended warranty program. The acronym stands for Mavic Product Protection Plan, and it provides you with two years of almost unlimited no-fault protection from Mavic. More details can be found on the MP3 website. Please note that MP3 coverage must be purchased within 5 days of the date that you receive your wheels. You'll get an email from us the day after your online wheel purchase, containing the retailer and product codes that you'll need to register your wheels on the Mavic MP3 site. You'll also need the serial numbers that you'll find on your wheels. The cost for this coverage is approximately 8% of the retail cost of the wheels.
The Mavic Crossmax ST Disc Wheelset is available in Black with White hubs and comes with a quick-release for the rear wheel, and a 15mm thru-axle for the front. Adapters to run a 20mm thru-axles or 9mm standard quick-releases on the front wheel are sold separately. The rear wheel can also be adapted for a 12x142mm thru-axle. Mavic recommends tire widths from 1.5-2.3”.
