With the new Cosmic Carbon Pro SL-C and the Ksyrium Pro Carbon SL-C, Mavic now feels it has found a manufacturing process that meets its safety standards. By using multiple layers of seamless one-piece carbon fibre for the rim bed, Mavic can produce a rim contour that meets ISO and ETRTO [European Tyre and Rim Technical Organisation] safety standards straight out of the mould without any need to cut or machine the fibres (which could weaken the structure of the rim).

Creating the new rims has allowed Mavic to move to a wider profile with a 17mm bed for both wheelsets. The Cosmic Carbon Pro SL-C rim is 40mm tall compared to 25mm for the Ksyrium Pro Carbon SL-C, and according to Mavic, the new Cosmic rim weighs 450g compared to 400g for the Ksyrium rim. Interestingly, after so many years of adhering to a sharp V-profile for Cosmic rims, Mavic has moved to a rounder shape for the new all-carbon version.

Mavic will be releasing two versions of each wheelset, one to suit rim brakes, and one for disc brakes. The former will incorporate Mavic’s updated iTgMax technology, a proprietary heat-treatment protocol that increases the Tg (melting temperature of the resin) for superior heat resistance of the brake track. The claimed result from this treatment is that the resin should be able to withstand more than 200°C, which is well in excess of typical braking temperatures.

The hubsets are built around hollow axles that can be married with different end-caps for compatibility with different axle systems (standard quick release versus thru-axles), which is most relevant important for the disc-equipped versions of each wheelset. As with all of Mavic’s other wheelsets, there will be a choice of freehub bodies to suit Shimano/SRAM and Campagnolo cassettes, while the disc-equipped wheelsets are compatible with center-lock rotors.

WEIGHT, PRICING AND AVAILABILITY

Mavic reports that the Cosmic Carbon Pro SL-C wheelset weighs 1,450g compared to 1,390g for the Ksyrium Pro Carbon SL-C. As such, neither wheelset will be the lightest in its class, but nevertheless, they are competitive. 

The Cosmics and Ksyriums are set to retail in the US for US$2,200 for both rim- and disc-brake versions. UK buyers can expect to pay £1,450 for rim-brake Cosmics while the disc-brake version will cost £50 more. The Ksyriums will retail for £1,500 and £1,575, for the standard and disc versions, respectively. Pricing for other markets (including Australia) is yet to be determined.

Release dates for both wheelsets are just around the corner. The Cosmic Pro Carbon SL-C wheelset for rim brakes will hit dealers in the US, UK and France on March 15, while the disc-brake version will arrive April 15. All other other territories will have these wheels on May 1. As for the Ksyrium Pro Carbon SL-C, the rim- and disc-brake versions are set for worldwide release on June 1.

Mavic will be operating its new “Riding is believing” demo program from April 15 in the UK and France, and from May 1 for the rest of the world, through which retailers will have demo wheelsets on hand for free, no-obligation test rides.
