Cosmic Carbone SLS Road Wheelset - Clincher

Mavic’s Cosmic Carbone SLS Wheelset occupies a bit of an esoteric space in the wheel market these days. They’re alloy rims paired with an aerodynamic, but non-structural, carbon fiber fairing. This nets you all of the benefits of an aluminum rim: powerful, consistent braking, impact resistance, and overall reliability, with nearly all of the benefits of a true, deep-dish carbon fiber wheel, all at just a hair under 1700g. Not the lightest wheels, to be sure, but if pure, flat speed is your goal, the Cosmic Carbone is a great option.

The wheels come complete with Mavic’s Yksion tires, quick releases, valve extenders, and a hub wrench. They’re laced radially in the front and radial/two-cross in the rear for a balance of stiffness and aerodynamics.
