Mavic COSMIC S 42 DISC 21 mm

Welcome to a new dimension of cycling.

The Mavic Cosmic S 42 wheelset, with its ultra-light full-carbon rims, offers instant acceleration and improved control. Thanks to an internal width of 21 mm, the wheels maximise tyre volume, boost confidence, improve efficiency and optimise cornering behaviour. Its design perfectly handles the stresses associated with disc brakes and ensures exceptional handling and braking power.

A profile height of 42 mm and wind tunnel-tested flat spokes maximise the aerodynamics of the Cosmic S 42 Disc and ensure lateral stability at high speeds. Cyclists seeking versatility on slightly hilly roads or in the mountains will find what they’re looking for here. The low weight guarantees excellent performance on the toughest climbs, allowing you to tackle Alpe d’Huez as if it were a hill. Mavic’s UST Tubeless Ready technology simplifies tyre fitting and ensures greater comfort and efficiency. High-quality spokes, durable bearings and our ID360 freehub technology ensure exceptional strength and longevity. The Cosmic S 42 Disc is hand-built in Europe and is the result of Mavic’s extensive experience in manufacturing high-quality wheelsets.

The exceptional dynamics and remarkable smoothness of the Cosmic S 42 Disc offer versatile options for cyclists seeking optimal performance in all conditions. With its reliability and ease of maintenance, it is a long-lasting investment ready for any challenge. Don’t spend too long searching for the ideal wheel: the Cosmic S 42 Disc is here to bring a legendary level of performance and perfection to your ride.

Mavic Infinity Classic Disc hubs:

the Classic 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 Infinity Disc Hub Compatibility:

The oversized aluminium axles allow for easy conversion to all standard axle systems. The Infinity front hub is compatible with QR9x100mm quick-release and QR12x100mm thru-axle mounts, whilst the Infinity rear hub is compatible with 10x135mm quick-release mounts and 12x142mm and 12x135mm thru-axles.

Mavic Cosmic S 42 Tubeless Disc rims:

The 42 mm high full-carbon aero rims with a 21 mm rim width are perfectly designed for tyre widths of 25–45 mm. The new rim profile offers the best possible aerodynamics. The Adaptive Carbon Lay-Up allows for a weight saving of 70 grams during rim production. Unlike other wheelsets with a uniform lay-up, this exclusive draping technique allows the carbon thickness to be varied locally, depending on the varying demands placed on the wheelset. Specifically, less material is used between the spokes, whilst the rim is reinforced at the spoke holes where stresses are highest. All this without ever compromising the stiffness and strength of the wheel for dynamic riding.

Hooked / Crotchet tubeless TC:

Hooked rims, or Crotchet rims, refer to the shape of the rim flange, which features a so-called hook. This supports the tyre bead and ensures that the tyre cannot come off the rim, even when using high tyre pressure > 5 bar. Tubeless means that the rim can be ridden without an inner tube, but a setup with an inner tube is also possible.

Mavic stainless steel spokes:

The durability of Mavic stainless steel spokes is exceptionally high.

Mavic Tubeless System:

The new rim bed makes fitting tubeless tyres easier. The pronounced and wider grooves in the rim bed significantly simplify tubeless fitting. Mavic is thus setting the standard for easy 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 a 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.
