COSMIC SLR 45
COSMIC SLR 45 Less weight where it matters


Unique and patented technologies to deliver light, fast and strong wheels.


Less inertia and lower weight ensure responsive acceleration and faster climbing
New rim laminate and the Fore Carbon spoke attachment saves 40g and eliminates rim tape — an additional 30g saving. The 45mm deep and 26mm wide NACA rim profile is disc-brake-optimized. Patented lightweight aero spokes.

Increased lateral stiffness for increased power transfer
Fore Carbon Technology keeps the rim upper bridge solid and leads to a stiffer rim. A stiff axle, durable bearings, and an all-new hub design with optimized spoke lacing and tension. ID360 freewheel technology enables increased compatibility and optimal power transfer.

Refined tubeless technology ensures faster rolling and easy setup and maintenance
No tubes mean less friction, improved efficiency and grip, and a reduced risk of punctures. An all-new rim bed form makes mounting and changing tires effortless. Fore Carbon drilling technology makes rim tape a thing of the past.

Tyre Sealant
Mavic Tyre Sealant is an effective tyre sealant, that prevents flat by instantly sealing up to 3 mm holes in the tyre

Freehub Body
ITS-4 and ID360 freewheel bodies to convert to the various drivetrains compatibility (Shimano/SRAM, Campagnolo, SRAM XD...)
