Dominate every ride with the Cosmic SL 45 Disc, a versatile carbon wheelset engineered for speed and efficiency
What Our Gearhead® Experts Are Saying:
"I’ve been running the Cosmic SL 45 Disc wheels for months and they strike a perfect balance between speed and reliability. The 45mm depth offers noticeable aero gains without getting twitchy in crosswinds, and the ID360 hub engagement is super quick for punchy climbs or aggressive sprints."
We ride fast, climb hard, and expect our wheels to hold nothing back—and the Mavic Cosmic SL 45 Disc Wheelset keeps up every step of the way. Whether we're hammering through a crit or chasing KOMs on rolling terrain, these lightweight carbon wheels bring aerodynamic efficiency and snappy acceleration to every turn of the pedals. Mavic’s proven engineering makes them our go-to for road performance without compromise.
The 45mm deep rims provide aero benefits without the sketchy sidewind handling of deeper profiles, and the hookless, tubeless-ready construction lets us run lower pressures for a smoother, faster ride. We love the ultra-responsive ID360 ratchet hub—it gives instant engagement for jumpy attacks and fast getaways. With a rim brake-free design and centerlock disc compatibility, they’re fully tuned for modern road machines.
