Mavic Crossmax Elite Carbon MTB Rear WheelThis mountain bike (MTB) rear wheel features a 100% unidirectional carbon fibre rim construction, which delivers the best balance of stiffness, durability and an overall low weight on your ride. Its tough properties make it perfect for handling all the challenges associated with XC racing and trail-riding, while its lightweight build ensures that it rolls efficiently without any excess weight holding you back when climbing or descending.Straight-Pull Spokes and Sealed Cartridge BearingsWhether you’re into XC racing or MTB trail-riding, this rear wheel’s straight-pull, round steel spokes provide lighter, stiffer rolling efficiency on the most demanding of terrain conditions. Mavic has also kitted out this model with auto adjust sealed cartridge bearings (QRM Auto) for high durability effectiveness thanks to low play and tight tolerances. Another highlight is its Boost axle spacing, which delivers additional stiffness and strength as you dominate your way around the mountain.6-bolt Disc Brake Compatibility and Tubeless Ready TechnologyThis MTB rear wheel is equipped with 6-bolt disc brake compatibility, so you can enjoy powerful and responsive braking performance as you keep your momentum flowing from trail to trail. Coming complete with a hookless rim profile with tubeless-ready technology, you’ll also benefit from the ability to run lower tyre pressures for tubeless advantages such as lower rolling resistance, increased stability on rough terrain and fewer chances of flats or punctures.Features: Rim Material: 100% Unidirectional Carbon Fibre with hookless profile Use: Cross Country (XC), Mountain Bike (MTB) Axle Size: 12x148mm Internal Rim Width: 26mm ETRTO: 622x26TSS Rim Profile: Hookless profile Drilling: Traditional Tubeless Ready: Yes Tyre Compatibility: Hookless compatible UST Tubeless and tubetype Recommended Tyre Sizes: 46mm to 64mm (1.8" to 2.5") Valve Hole Diameter: 6.5mm Spoke Material: Steel Spoke Count: 24 Spoke Shape: Straight-pull, round Wheel Hub Body: Aluminium Axle Material: Aluminium Freewheel: Instant Drive 360 Freehub Compatibility: SRAM XD Bearings: Auto adjust sealed cartridge bearings (QRM Auto) Brake Compatibility: 6-bolt disc brake Max Rider Weight: For a longer longevity of the wheel, Mavic recommends that the total weight supported by the wheels doesn’t exceed 120kg, bike included ASTM Category 3: Cross country and trail riding Single or Pair: Single rear wheelManufacturer’s Part Numbers: LR2403100 Black 29" SRAM XDBuy Mavic Wheels & Tyres from Chain Reaction Cycles, the World’s Largest Online Bike Store.
