For anyone looking to burn up the XC course, this lightweight and efficient 29" wheel offers the world's easiest tubeless system at an attainable price.**Faster accelerating and climbing capabilities**Fore technology sealed rim design minimizes weight and increases strength. Eliminating rim tape saves 30g per rim. Ultra-reliable ID360 freewheel system for instant engagement.**Increased traction and durability**25mm wide hookless rim profile optimized for lower tyre pressures, resulting in improved grip in all conditions. Optimized for modern XC tubeless tires from 2.1 to 2.30". Black Shield treatment protects rims against impacts and scratches.**Most user-friendly tubeless system**Fore technology fully sealed rim with no rim tape makes it easy to mount and change tubeless tires. Leaving the upper rim bridge intact boosts the stiffness and durability of the rim.**Weight Pair: 1695g****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**The name Crossmax has a long history in the world of XC riding and racing, and the new Crossmax SL lives up to that legacy. It offers many of our proven Mavic technologies at an attainable price. Weighing just 1700g, it’s a true all-rounder and the best alloy XC wheel in its category.The rims are made with our patented Fore technology featuring a fully sealed upper rim bridge that eliminates the need for rim tape. That saves 30 grams per wheel, not to mention the hassle of using tape to set up tubeless tires. The rim has a 25mm internal width with a durable hookless profile, and our Black Shield technology gives them a distinctive, modern look that protects against scratches and abrasions.We use 24 straight-pull spokes (same spoke length throughout) for a strong connection between the rim and hub and a perfect balance between efficiency and durability. Special machining on the hub ensures that the spoke head is secured but can still travel in the slot. This allows the wheel to absorb impacts from trail obstacles. Our Instant Drive 360 freewheel coupled with QRM Auto bearing technology provides fast engagement and added durability. The Crossmax SL 29 is compatible with Shimano HG9, Micro Spline and SRAM XD driver bodies. It’s 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, replacement spokes and accessories.**Maxtal aluminium alloy**Light and strong. Exclusive to Mavic, this specific aluminium alloy offers a higher strength to weight ratio than the conventional 6106 alloy.**ISM Light rim technology**Inter Spoke milling is an exclusive Mavic patented concept. ISM involves the machining of the lower bridge of the rim between each spoke hole to create a light and rigid rim without reducing durability**Fore Carbon tapeless tubeless technology**Stiffer and stronger. A fully sealed upper rim bridge eliminates the need for rim tape. The spokes are directly screwed in the insert. A threaded metallic insert is wrapped inside the carbon layups of the lower rim bridge.**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.**SUP Welding technology**Soude Usine Process, stronger and smoother joint. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.**Black Shield treatment (protects against impacts and scratches)**This treatment doubles the rims lifespan against stone impacts and scratches. Super strong double coated treatment with a matt finish.**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: 22mm* Inner width: 25mm* Front axle: 15x110mm* Rear axle: 12x148mm* Discipline: MTB - Cross Country* Spokes: Steel, Straight, extra flat* Rim Diameter: 29"* Nipples: Brass Black* Rim material: Maxtal Alloy* Tyre compatibility: UST Tubeless Ready* Maximum weight: 150kg including bike* Braking system: Centre lock or 6 bolt* Bearings: QRM automatic setting - sealed cartridge* ETRTO Size: 622x25TSS* Weight: 1695g**What's in the box?*** Wheelset* User guide* UST Valve not mounted on the wheel* 2 replacement spokes for each wheel* 2 Multifunction adjustment wrench with rear wheel**Intended Use*** Minimum tyre size: width 30mm - pressure max. 4.05Bar/59PSI* Maximum tyre size: width 64mm - pressure max. 2.45Bar/36PSI* ASTM category 3 : cross country
