Mavic Cosmic SLR 45 Disc Center Lock Shimano

Mavic Cosmic SLR 45 Disc 23mm Center Lock Shimano

The new Cosmic SLR 45 is not just an update, but a complete redesign of the most versatile wheel. With its 23 mm wide inner rim and ceramic bearings, it is the go-to choice for cyclists looking to optimise their performance on any terrain. It is lighter, more stable in crosswinds (Aero Wide Rim / Aero Spokes) and, thanks to the absence of a rim floor (Fore Carbon), incredibly responsive. It offers predictable handling and instant power transfer. Whether sprinting or climbing – it transforms every pedal stroke into pure acceleration. The Cosmic SLR 45 transforms your bike into a highly efficient racing machine, whatever the profile of your ride.
