At just \n1080g a pair, it's engineered for racers who need every gram and every \nwatt working in their favour.\u003c\/p\u003e\u003cp\u003eEvery part of this wheelset has been rebuilt from the ground up in pursuit of pure XC speed. The Adaptive Layup carbon rim construction cuts weight without giving up the stiffness and strength that racing demands, while carbon spokes paired with titanium nipples shave a further 100g from the build. An ultralight hub, just 180g, runs on Mavic Ceramic bearings to keep friction to a minimum, so power goes straight into forward motion rather than getting lost along the way.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.chickencyclekit.co.uk\/mavicwarranty.php\"\u003e\u003cimg src=\"https:\/\/www.chickenb2b.co.uk\/image_library\/mavic-lifetime-banner-thinned1.jpg\" alt=\"ALT TEXT HERE\"\u003e\u003c\/a\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eResponsiveness is where the Crossmax Ultimate really sets itself apart. Mavic's proven 40-tooth ID360 LIGHT ratchet freewheel gives near-instant engagement the moment pressure hits the pedals, making every acceleration and every technical climb feel sharper. It's a wheelset already proven at the top level, with podium finishes and top-10 results across the 2026 UCI Mountain Bike World Cup season with the KTM and Mondraker factory teams.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRim height: 25mm\u003c\/li\u003e\n\u003cli\u003eInner width: 30mm\u003c\/li\u003e\n\u003cli\u003eExternal width: 36mm\u003c\/li\u003e\n\u003cli\u003eFront axle: 15 x 110mm\u003c\/li\u003e\n\u003cli\u003eRear axle: 12 x 148mm\u003c\/li\u003e\n\u003cli\u003eDiscipline: XC\/MTB\u003c\/li\u003e\n\u003cli\u003eSpokes: Carbon\u003c\/li\u003e\n\u003cli\u003eRim Diameter: 29\"\u003c\/li\u003e\n\u003cli\u003eNipples: Titanium\u003c\/li\u003e\n\u003cli\u003eRim material: T700, T1000, 3K Adaptive layup Carbon\u003c\/li\u003e\n\u003cli\u003eTyre compatibility: Tubeless Ready\/Clincher\u003c\/li\u003e\n\u003cli\u003eMaximum weight: 135kg including bike\u003c\/li\u003e\n\u003cli\u003eBraking system: Centre lock\u003c\/li\u003e\n\u003cli\u003eBearings: Mavic Ceramic\u003c\/li\u003e\n\u003cli\u003eWeight: 1080g\u003c\/li\u003e\n\u003cli\u003eFront Weight: 500g\u003c\/li\u003e\n\u003cli\u003eRear Weight: 580g\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat's in the box?\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWheelset\u003c\/li\u003e\n\u003cli\u003eUser guide\u003c\/li\u003e\n\u003cli\u003eUST valve not mounted on the wheel\u003c\/li\u003e\n\u003cli\u003eUST rim tape mounted on wheel\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eUnderstanding the different Mavic freehub body acronyms:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHG or M11 – Shimano HG Road 11\/12x (other speeds with spacer)\u003c\/li\u003e\n\u003cli\u003eMS - Shimano Microspline\u003c\/li\u003e\n\u003cli\u003eXD - SRAM XD\u003c\/li\u003e\n\u003cli\u003eXD-R - SRAM XD-R\u003c\/li\u003e\n\u003cli\u003eED11 - Campagnolo 9\/12x\u003c\/li\u003e\n\u003cli\u003eN3W - Campagnolo 13x\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecific Mavic Adaptive Layup\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eMavic's \nAdaptive Layup technology optimises every carbon fibre layer to achieve \nthe ideal balance of low weight, lateral stiffness and vibration \nabsorption.
