The invention is based on the problem of how to improve in ski or snowboard the transfer of forces from the ski bindings fixation area to a respective ski edge (51, 52), i.e. to increase torsional stiffness or decrease torsional deformations around the longitudinal axis without interfering in any way with existing flexural properties or existing dimensions of a ski or a snowboard, especially without any additional elements which would extend or would be arranged out of standard dimensional ranges of currently commercially available skis or snowboards. The ski or the snowboard comprises a slide layer (5) with ski edges (51, 52) and a lower bearing assembly (6) consisting in each case, preferentially, of respective number of laminate layers (61, 62) above which a core (7) with respective lateral sides (71, 72) is installed. Over the core (7) and the lateral sides (71, 72), a carrier (100) is installed, designed as a one-piece element made of transformed plate material, for example either of a laminate or also, in principle, of a suitably shaped sheet metal, appropriate plate or sheet or similar flat semifinished product made of metallic or non-metallic material. Izum temelji na problemu kako pri smucki ali snezni deski izboljsati prenos sil iz obmocja pritrditve smucarskih vezi na vsakokratni robnik (51, 52), t.j. povecati torzijsko togost oz. zmanjsati torzijske deformacije okoli vzdolzne osi, ne da bi bilo v ta namen potrebno kakorkoli posegati v obstojece upogibne lastnosti in obstojece izmere smucke ali snezne deske in se zlasti tudi brez vsakrsnih dodatkov, ki bi segali oz. bi bili razporejeni izven obicajnih dimenzijskih okvirov tacas komercialno dostopnihsmuci ali sneznih desk. Smucka ali snezna deska obsega drsno plast (5) z robnikoma (51, 52) ter spodnji nosilni sklop (6), ki prednostno sestoji iz vsakokrat ustreznega stevila laminatnih plasti (61, 62), nad katerimi je vgrajeno jedro (7) s pripadajocima bocnima stranicama (71, 72). Preko jedra (7) in bocnih stranic (71, 72) je namescen nosilec (100), ki je enovito zasnovan iz ustrezno preoblikovanega ploscnatega gradiva, npr. bodisi iz laminata ali naceloma lahko tudi iz ustrezno preoblikovane kovinskeplocevine ali ustrezne plosce ali folije ali podobnega ploscnatega polizdelka iz kovinskega ali nekovinskega gradiva.
