Ifuro ry'icyuma ni selile ya selile igizwe nicyuma gikomeye (akenshi aluminium) hamwe na poro yuzuye gaze igizwe nigice kinini cyijwi. Urwobo rushobora gufungwa (gufunga-gufunga ingirabuzimafatizo) cyangwa guhuzwa (gufungura-selile ifuro). Igisobanuro kiranga ifuro ryicyuma nikintu kinini: mubisanzwe 5-25% gusa byijwi nicyuma fatizo, bigatuma ibyo bikoresho bya ultralight. Imbaraga zibikoresho biterwa na kare-cube amategeko.

Ifuro ryibyuma risanzwe rigumana ibintu bifatika bifatika. Ifuro ikozwe mu cyuma kidacanwa ntigishobora gutwikwa kandi muri rusange irashobora gukoreshwa nkibikoresho fatizo. Coefficient yo kwagura ubushyuhe irasa mugihe ubushyuhe bwumuriro bushobora kugabanuka.

Nubwo patenti nyinshi zisobanura imiterere yimiterere ya topologiya, ibikoresho byubaka, nuburyo bwo kubyaza umusaruro, ifuro ryibyuma ntirishobora gufatwa nkibicuruzwa kandi ni bike mubicuruzwa byubucuruzi biboneka kwisi yose.
