Crossmax Sl Ultimate 30 29 Disc Centre Lock

Built for Olympic athletes, the new Crossmax SL Ultimate is the most dynamic XC wheelset ever created by Mavic. Lighter, stiffer, faster - it's all about going for gold. **Fly up climbs and accelerate faster** New carbon Adaptive layup technology shaves 70g per rim. a 25mm wide rim weighs only 340g. **Stiff and smooth ride quality** Special carbon rim layup for superior rim stiffness and added control on descent. Double-butted, two-cross spoke pattern for enhanced vertical compliance. **Efficient power transfer** New lighter Infinity hub design paired with 24 straight-pull spokes for improved stiffness and better balanced spoke tension. **Weight Pair: 1395g** **Understanding the different Mavic freehub body acronyms:** * HG or M11 – Shimano HG Road 11/12x (other speeds with spacer) * MS - Shimano Microspline * XD - SRAM XD * XD-R - SRAM XD-R * ED11 - Campagnolo 9/12x * N3W - Campagnolo 13x ___ **ADDITIONAL INFORMATION** At only 1395 grams, this is the wheel that performance obsessed cross-country racers dream of. Developed with input from top pro racers seeking a competitive advantage at World Cups and Olympics, it features an ultralight full carbon 29" rim (360g) for fast acceleration and climbing without compromising stiffness and durability. Adaptive layup, a specific carbon layup technology enabled us to handcraft these carbon rims with less material between the spokes. The spoke holes are reinforced with strategically positioned carbon layering in a process that minimizes weight without compromising stiffness and strength. A lighter rim means faster acceleration, more efficient climbing, and a more responsive feel on the trail. The external carbon layer features our new UD2 construction for a distinctive look and added durability. Extensive field testing with our pro athletes determined that a 25mm inner width was ideal for a quick, precise ride quality and optimized tyre grip on fast racetracks. For more technical trails, some preferred a 30mm width for added control, so we created two options. It’s your choice, and you can mix the two if you want. You could choose the Crossmax Ultimate 25 for the rear to boost acceleration and efficiency, and the Crossmax Ultimate 30 for the front to add confidence and control on rugged single track. The carbon rim is laced with 24 straight-pull double butted spokes (same spoke length throughout), two-crossed for maximum power transfer and enhanced vertical compliance. The new lighter Infinity hub design optimizes lateral stiffness, and the spoke lacing maximizes power transfer. Our Instant Drive 360 freewheel with a double ratchet system provides fast engagement and high stiffness to help you accelerate out of corners faster. The rear hub is compatible with Shimano HG9, Micro Spline and SRAM XD driver bodies. The Crossmax SL Ultimate 30 is available with 6-bolt or centre lock brake rotors in 29" only and is compatible with a 15x110 front axle and 12x148 rear. It comes with valves, spare spokes and MTB wheel covers. **Adaptive Layup Carbon Technology** Strategically positioned carbon layering with local reinforcement at spoke holes for a maintained durability. Rim is 17% lighter with adaptive layup. Lighter carbon rim construction for faster acceleration and more efficient climbing. The Ultimate Cross Country racing application: light and responsive. **Instant Drive 360 technology** Super light and efficient. The large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile. **UST tubeless technology** Traction and control. Universal Standard for Tubeless. Ready to ride tubeless system. The UST concept improves traction, control and comfort whilst reducing inertia and flats. **Infinity Hub Design** Efficient power transfer thanks to optimised non contact spoke lacing (no noise under load) and tension distribution. The length of the spokes at the front and rear is identical. Maintenance is easy thanks to a tool free solution. **QRM Auto bearing preload technology** Qualite de Roulements Mavic Auto. Cartridge bearings double sealed with e3 internal clearance. Preload is automatically adjusted to guarantee a perfect spin with no play on the long run. **Technical Specifications:** * Profile depth: 30mm * Inner width: 25mm * Front axle: 15x110mm * Rear axle: 12x148mm * Discipline: MTB - Cross Country * Spokes: Steel Straight Extra Flat * Rim Diameter: 29" * Nipples: Aluminium Black * Rim material: Material: 100% carbon fibre with UD external layer * Tyre compatibility: UST Tubeless Ready * Maximum weight: 150kg including bike * Braking system: 6 Bolt or Centre Lock * Bearings: QRM automatic setting - sealed cartridge * ETRTO Size: 622x30TSS * Weight: 1395g **What's in the box?** * Wheelset * User guide * Wheel Cover * Rim Tape mounted on wheels * UST Valve not mounted on the wheel * 2 Replacement spokes for each wheel * Multifunction adjustment wrench
