Mavic Cosmic S 42 Wheelset

Built with Shimano HG, Conversions Available.

The Mavic Cosmic S 42 Wheelset delivers the aerodynamic advantages of a carbon road wheelset in an accessible, durable package designed for everyday performance. Built for riders who want to upgrade from alloy wheels to carbon, the Cosmic S 42 provides improved speed, efficiency, and ride quality for road riding, training, and fast group rides.

Featuring a 42mm carbon rim depth, the Cosmic S 42 strikes a balanced middle ground between lightweight climbing wheels and deeper aero race rims. This depth offers meaningful aerodynamic benefit at speed while maintaining predictable handling and crosswind stability, making it well suited for varied terrain and real-world riding conditions.

The rim profile is optimized for modern road tire widths, improving tire shape and rolling efficiency while increasing cornering confidence and comfort. The tubeless-ready design allows riders to run lower tire pressures for better traction and reduced puncture risk, creating a smoother and more efficient ride over rough pavement.

Mavic pairs the carbon rims with a dependable hub system and durable spokes to create a wheelset that is both performance-oriented and reliable for daily use. Designed exclusively for disc brake road bikes, the Cosmic S 42 offers modern compatibility and consistent braking performance.
