COSMIC SL 40

specifically for rim brakes. Our proven iTgMax technology features a patented laser treatment of the braking surface, which reduces braking distance in both dry and wet conditions, whilst a special lay-up and heat treatment process makes them the strongest and most durable of all carbon rims for rim brakes. They are available for Shimano cassettes and can be converted to Campagnolo and SRAM XD-R with optional drive bodies. These wheels were designed, developed and patented by Mavic in Annecy, France, and are 100 per cent hand-built in our European carbon factory.

Mavic Infinity hubs:

The completely newly developed Infinity hubs are equipped with a larger 17 mm axle diameter and larger bearings. This increases the torsional stiffness of the axles by approximately 35 per cent. The proven Mavic QRM auto industrial bearings are used in the Infinity hubs. Equipped with the Instant Drive sprocket freehub body, the ORM auto axle system and self-aligning bearings, they ensure maintenance-free operation over a long period.

Mavic Cosmic SL 40 Clincher Rims:

The 40 mm high and 26 mm wide aero rims with a 19 mm rim width offer excellent aerodynamic and acceleration performance. Mavic’s iTgMax rim technology provides the best possible resistance to heat build-up. The rim features a NACA rim profile with a depth of 40 mm and a width of 26 mm, specifically designed for all-round performance on flat or undulating terrain. The new rim bed shape makes it easier than ever to fit tubeless and clincher tyres. Riding UST tubeless means no inner tube and therefore no friction, and greater air volume means a smoother ride. The result is a faster ride with extremely low rolling resistance.
Thanks to improved spokes, this wheelset is 80 g lighter than its predecessor, the Cosmic Pro Carbon UST. Combined with our new Infinity hub platform, which ensures a fast and responsive ride out of every corner, they are stiffer and more efficient.

Mavic Aero spokes:

The patented elliptical spoke shape significantly improves aerodynamics. The durability of Mavic stainless steel spokes is exceptionally high.

Mavic Tubeless System:

The new rim bed, with its pronounced and wider grooves, makes tubeless fitting significantly easier. Mavic is thus setting the standard for simple tubeless fitting. The fitting process is no different from that of standard folding tyres. This allows the advantages of tubeless tyres – lower rolling resistance, greater riding comfort and reduced risk of punctures – to come into their own.

Of course, the Mavic Cosmic wheels can also be used with standard folding and clincher tyres and inner tubes without any issues. When out and about, we recommend carrying a standard inner tube as a quick puncture repair solution.
