Thanks to its 23mm aero shaped profile, the CXP Pro slices through the air, while its Maxtal alloy keeps its weight astonoshingly low, making for a great value wheelset. SUP welded and eyeleted, the CXP PRO is also very strong and durable. The Maxtal alloy is exclusive to Mavic, and it offers aluminium at a higher strength to weight ratio than conventional 6061 alloy. SUP or Soude Usine Process is a process that involves the rim. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish. The Miche Reflex hubs are CNC machined and guarantee high fluidity with high precision bearings. **Mavic CXP Pro Specs:** * Material: Maxtal 6016 alloy, higher strength to weight ratio than 6061 alloy. * Rim: Arc welded then milled for a smooth finish * Braking surface: CNC Machined **Miche Reflex Hub Specs:** * Adjustment System: Friction Cone front/ Smoothness adjustment ring rear * Freewheel Body: AL 7075 T6 (SH/CA) * Front And Rear Body: AL 6061 T6 * Axle Material: Steel * Bearings: Miche
