Technical Excellence & Details

• 42mm NACA Profile: The rim shape has been engineered to minimize drag and maximize stability. With a 21mm internal width, it pairs perfectly with 28mm tires for superior comfort and efficiency.

• Instant Drive 360 Freehub: The dual-ratchet system ensures ultra-fast engagement (only 9°) and simplified maintenance. Power transfer is immediate and smooth.

• UST Tubeless Ready: Mavic is a pioneer in Tubeless technology. Thanks to the UST rim design, mounting and removing tires is easier than ever, offering less friction, more comfort, and zero pinch flats.

• Optimized Spoking: Straight-pull flat spokes ensure superior lateral stiffness and ideal load distribution for disc braking forces.
