ROSE Bikes Cosmic S 42 Disc 28“/700C Road Rear Wheel SHIMANO HG| Road

The S 42 Disc rear wheel gives you access to Mavic’s legendary Cosmic model range and thus to the world of high-performance carbon wheels from the traditional French manufacturer.

The combination of the 42 mm high yet lightweight aero carbon rim and the 24 flow-optimised spokes makes the wheel an outstanding all-rounder that masters the balancing act between speed sessions on flat terrain and steep climbs with ease. The Cosmic S 42 harmonises perfectly with 28 mm wide road tyres in terms of aerodynamics. Thanks to the 21 mm inner rim width, you can of course also fit wider tyres. In any case, you benefit from Mavic’s UST tubeless technology when riding tubeless. This gives you lower rolling resistance, increased puncture protection and more comfort.

No half measures were taken with the hub either: Mavic’s Instant Drive 360 toothed disc freewheel with 9° degree engagement ensures lightning-fast propulsion and high durability. In addition, the self-aligning industrial bearings optimise the hub’s rigidity and power transmission as well as its ease of maintenance.

With these features, the Cosmic S 42 Disc rear wheel stands out as an affordable yet high-quality carbon wheel that is right up to date thanks to modern technical features and is therefore an excellent upgrade for your bike.

Top technologies:
UST tubeless technology: Refers to Mavic tubeless technology, in which the rim and tyre are perfectly matched for a complete tubeless system through exact harmonisation.
