Mavic Cosmic SLR 45 23i Carbon Wheel Black, Rear, HG, 12x142mm

"What Our Gearhead® Experts Are Saying: ""I’ve ridden the Cosmic SLR 45s across everything from race days to long solo training rides, and they never disappoint. The 23mm internal width smooths out rough pavement, and tubeless setup is incredibly easy thanks to the undrilled FORE rim bed. They’re light, stiff, and roll effortlessly—especially with the new ceramic bearings. The front cuts clean through crosswinds, and the rear’s engagement feels instant when you step on the gas. It’s Mavic performance at its sharpest.""We reach for the Mavic Cosmic SLR 45 Disc front and rear wheels when we want that pro-level ride feel every day. Designed and built in Europe, this pair brings together aerodynamic shaping, wide carbon rims, and the precision of ceramic bearings for speed and reliability on any terrain. The 45mm deep unidirectional carbon rims strike that perfect balance between climbing efficiency and all-out aero performance, while the 23mm internal width supports modern wide tires for smoother rolling and confident cornering. Both wheels use Mavic’s innovative FORE carbon tapeless tubeless system, creating an airtight seal and eliminating the hassle of rim tape for faster setup and less maintenance. The 24 straight-pull spokes and 2-cross lacing add stability and stiffness under hard efforts. The rear hub adds Mavic’s premium ceramic bearings. Whether we’re racing crits, grinding out century rides, or hunting KOMs on mountain descents, these wheels bring confidence and speed to every mile."
