Mavic Cosmic SLR 40 Clincher Wheelset 2021

The Mavic Cosmic SLR 40 Clincher Wheelset blends a sophisticated carbon fibre construction, an aerodynamic design and a refined braking surface to give a versatile performance that excels over any parcours.

The advanced carbon material used in the construction of the rims keeps the weight low while improving lateral rigidity markedly. This carbon material uses a specific resin within the brake track area and this partners with a special laser-etched surface to enhance braking performance and temperature regulation in all conditions. The stiffness to weight ratio of the rims is improved further by Mavic’s Fore Carbon Technology that integrates metal spoke thread inserts directly into the structure, cancelling the need for drillings in the upper rim bridge. This format also negates the need for rim tape when using tubeless-ready or standard clincher tyres.

The 40mm deep, wind tunnel tuned rim profile reduces aerodynamic drag and also stabilises the wheels during windy rides. This aerodynamic theme is continued by the elliptical spokes that save five watts of drag per wheel. Infinity hubs provide a solid base for these spokes to anchor into, regulating spoke tensions for heightened power transfer and durability.
