What Our Gearhead® Experts Are Saying:

"With its 65mm depth and lightweight construction, the Cosmic SL 65 Disc is the ultimate balance of speed and control. The aerodynamic profile cuts through the wind, while the new hub platform ensures every watt of power goes straight to the pedals. The UST tubeless system improves ride comfort and grip, giving me the confidence to push harder. If you're looking for a high-performance aero wheelset that doesn’t compromise stability, this is the one."

For riders chasing aerodynamic efficiency and rapid acceleration, the Cosmic SL 65 Disc Wheelset is a game-changer. The deep 65mm carbon rims are engineered with a NACA aero profile, optimizing airflow to reduce drag while maintaining stability in gusty conditions. Whether in a breakaway or pacing through a triathlon, this wheelset delivers unrivaled speed.

The Infinity hub platform refines spoke lacing for improved tension and power transfer, while the Instant Drive 360 freewheel ensures lightning-fast engagement for sprint-ready responsiveness. A redesigned UST tubeless-ready system makes tire setup easier than ever, allowing for lower rolling resistance, increased grip, and a smoother ride. Built for competitive cyclists and triathletes alike, the Cosmic SL 65 Disc is the pinnacle of aerodynamic performance.
