This is the XL style, all aluminum version of the very popular 940C combi. The rear wheel is harder than the rubber in the classic skis because the scrubbing motion in skating reduces tire life. The front ratchet wheel is narrower than the wheel used on the 900 classic skis and has a more crowned profile for better skate characteristics.
