Cosmic SLR 45 23i Wheelset

What Our Gearhead® Experts Are Saying:

"The Cosmic SLR 45 23i Wheelset is one of those upgrades you feel immediately. The 45mm depth carries momentum through flat and rolling sections without feeling sketchy in crosswinds, and the 23mm internal width opens up your tire options considerably for mixed surface riding. Tubeless setup was clean and straightforward thanks to the FORE construction doing away with rim tape entirely."

Gravel routes have a way of starting well-paved and ending somewhere far more interesting, and the Mavic Cosmic SLR 45 23i Wheelset is built for exactly that kind of day. The 45mm carbon rims punch through headwinds and carry speed efficiently across open sections of road, while the 23mm internal width gives modern gravel tires room to breathe, run at lower pressures, and smooth out whatever the surface throws at you.

Mavic's FORE carbon construction eliminates the need for rim tape, creating a clean, airtight tubeless foundation right out of the box. Ceramic bearings keep rolling resistance low over long miles, and the overall build strikes a balance between aerodynamic depth and the stability you actually need when the pavement ends and confidence matters most.
