About the Mavic Cosmic Elite WheelsetTop aero performance on disc-brake road bikes is now more obtainable than ever. UST Tubeless Road technology makes this new wheel-tire system faster and smoother. By removing the tube, we’ve also removed friction—so there’s less rolling resistance, which means it requires less energy to reach higher speeds. The UST system, including the sealant that makes the tires more resistant to punctures, is also 40g lighter than a traditional tube and tire system. Wind tunnel testing led us to create a 30mm deep rim that optimizes aero performance and improves stability in crosswinds. The alloy rim benefits from our unrivaled experience creating light yet strong rim extrusions. We do this by carefully tuning the thickness of the rim wall to hit the sweet spot between stiffness, strength and weight.It’s also engineered specifically for disc brakes, with steel-bladed straight-pull spokes that are stronger than traditional J-bend spokes, which are connected to our strongest hub platform running on smooth QRM bearings.Our extensive wind tunnel testing led us to create a 30mm deep rim that optimizes aero performance and improves stability in crosswinds.
