Cosmic SL 40 700c Carbon Rim Brake Front Wheel

The Mavic Cosmic SL 40 front wheel uses a 40mm-deep carbon rim to add aerodynamic efficiency without the weight and handling characteristics of a much deeper wheel. Mavic's iTgMAX carbon brake track is engineered specifically for rim-brake use, while the Infinity hub and lightweight spoke build keep the wheel responsive under acceleration and climbing. The 19mm internal rim width also gives it plenty of versatility for modern road tires.
Key Features

• 40mm-deep carbon rim balances aerodynamic efficiency, weight, and handling
• 100% carbon fiber rim keeps weight low
• NACA-inspired rim profile is designed to reduce aerodynamic drag
• iTgMAX brake track is engineered for consistent carbon-rim braking
• Infinity hub uses optimized spoke positioning for a responsive wheel feel
• QRM Auto sealed cartridge bearings automatically maintain bearing preload
• UST Tubeless Ready rim can be used with tubeless or tube-type tires

Who It's For
The Cosmic SL 40 front wheel is for road riders looking for a lightweight carbon upgrade for a traditional rim-brake bike. The 40mm depth makes it a versatile choice for riders who want some aerodynamic benefit on faster roads while still keeping the wheel light and manageable on climbs and rolling terrain.
