Mavic Ceramic: a premium material, premium performance

• With these special properties, ceramic makes the bearings slightly faster and more durable. In addition to this material, we use a premium, low-density grease and low-friction seals.

Aero Wide Rim: Unrivalled combination of speed, control and comfort

• Mavic's wider rims ensure a seamless transition between the rim and the tyre, reducing micro-turbulence
• Rolling resistance is significantly reduced, resulting in improved handling in crosswinds and a smoother, faster ride, even on rough terrain, thanks to a wider, shorter footprint and lower tyre pressure.

FORE: More rigidity and a sealed system for Tubeless

• The rim's upper bridge is threaded to receive the spokes directly at the correct angle. This provides a rigid connection, prevents spoke movement (reducing breakage), and ensures a 100% airtight upper bridge for easy tubeless setup.
