Built for these Olympic athletes, the Mavic Crossmax Carbon SL Ultimate 30 rear wheel becomes the most dynamic model in the Cross-Country range of the French brand Mavic. With an all carbon fibre Adaptive Layup design that adapts the different thicknesses according to the constraints of each part of the rim, this wheel allows a significant weight saving compared to the Crossmax Pro Carbon. The result is more incisive acceleration and increased climbing efficiency. In addition, the outer carbon layer benefits from the UD² design, which provides a distinctive visual identity and increases durability. The wheel has a hook-free profile for improved comfort, control and traction and a 30mm width for technical descents and better handling. In addition, it is fully UST compatible. It also benefits from an asymmetric design to better balance the tension between the spokes. The 24-spoke steel spoking, crossed in pairs at the front and rear, provides a perfect balance between lateral rigidity and vertical flexibility. Finally, the highly reliable Stellar Drive 80 freewheel system ensures ultra-fast clutching, providing incomparable responsiveness and dynamism.
