The Mavic Crossmax ST Disc 26 in. wheelset offers a super-stiff, lightweight and UST-compatible platform to not only deliver precise handling and burly strength, but a bucket full of awesome as well. Lightweight and strong, proprietary aluminum rims have a drilling method that doesn't penetrate the tube-facing wall, enhancing wheel strength and rigidity. This drilling method also helps wheels achieve UST tubeless compatibility, offering all the benefits of tubeless with the option of using a traditional tube/tire setup. Inter Spoke Milling along rim reduces material between spokes, lowering weight and the amount of effort needed to spin the wheels up for superb climbing and acceleration. Rim joints are welded and milled to maximize strength, rigidity and wheel balance while also offering a smooth finish. Rear hub uses Instant Transfer System 4 freewheel design to supply very fast engagement via 4 pawls, ensuring your energy is transferred to the wheel faster and efficiently. Double-sealed cartridge bearings deliver excellent longevity and smooth spinning; microadjustability lets you fine-tune bearing loads to optimize your ride. Front wheel uses 24 round, straight-pull Zicral alloy spokes laced in a 2-cross pattern; rear uses 20 spokes in a radial lacing on drive-side and 2-cross on non-drive-side. Front hub is compatible with either 15mm thru-axle or traditional 9mm quick-release; rear hub works with either 9mm or 12mm axles (adapters included). Compatible with standard 6-bolt disc brake rotors; 100mm front and 135mm rear axle spacing. The Mavic Crossmax ST Disc wheelset comes with quick-release skewers, removable UST valves, bearing adjustment tool and spoke wrench. Mavic's recommended maximum combined weight of the cyclist, bike and equipment is 220 lbs. (100kg); recommended tire width is 1.5 - 2.3 in.
