Ho hlahisa boqapi ba morao-rao ba sehlahisoa sa merafo le ho cheka - Diamond Composite Gear (DEC)!Sehlahisoa sa rona sa DEC se kopanya lisebelisoa tse ntle ka ho fetisisa tsa daemane le tse kopantsoeng ho u fa lisebelisoa tse phahameng tsa ho cheka tse fetang tebello ea hau.
Meno a rona a DC1924 a sephara a daemane a sephara a chesitsoe ka mocheso o phahameng haholo le likhatello tsa ho theha meno a thata le a tšoarellang a ka mamellang mathata a ho rafa le ho cheka.Mekhoa ea tlhahiso e tšoana le ea lipoleiti tse kopantsoeng tsa taemane, e netefatsang botsitso le ts'epahalo ho meno 'ohle a rona a motsoako oa litaemane.
