Ready for any terrain. A reliable alloy wheel system for your boldest Allroad adventures.KEY BENEFITS Traction, rolling efficiency and safety on all types of terrain. 650B with 45-50mm tires to retain the driving feel and handling of a normal bike The comfortable 5 cm "clearance" of the tires improves traction and comfort, avoids punctures and allows you to adopt the most suitable pressure according to the type of terrain you are dealing with. UST tubeless compatibility offers the least possible rolling resistance.Fast acceleration and smooth cornering grip.The union between the thin alloy rim and the double crossed spokes ensures the right balance of lateral stiffness and verticality.The superlight ISM 4D rim with hookless profile allows rapid acceleration. Double butted steel spokes for great comfort and control. Absolute reliability on any terrain. Mavic Road UST wheels reduce the risk of punctures. The Instant Drive 360 freewheel system and the QRM Auto bearings ensure performance and great reliability. Road cycling is always on new and more adventurous paths and this wheel system is designed to stay at the forefront of new trends. Ultra-wide rims (25mm internal) and a smaller 650B diameter allow you to use 45 to 50mm wide tires to better absorb shocks and vibrations from the bottom. But even with the additional 5cm of tire clearance, the smaller rim diameter maintains the agility typical of road bikes. Without any compromise. UST road tubeless technology offers the advantage of better rolling efficiency and a lower risk of punctures, not to mention that tubeless tires are easier to fit and inflate. These lightweight rims are made with ISM 4D (Inter Spoke Milling) technology, which removes material from the rim where it is not needed, keeping it around the spokes, where tension is concentrated.This disc brake specific wheel boasts 24 steel spokes front and rear to distribute braking torque efficiently and evenly. The wheels are compatible with Center Lock rotors. The front hub features a 12mm thru axle which can be converted to 15mm or quick release system. The rear wheel is equipped with a 12x142 thru axle, also convertible to the quick release system.
