Right, Ill type out the whole story to avoid confusion ONZA = NOT ENTIRELY ZONA ok? Why would onza decide they want to sell onza frames under a different name. YES they ARE related, onza factories manufacture zona frames and slap zona stickers on. I mean the relationship between the two is VERY close, but that doesn't mean they're the same friggin company! Zona have two frames currently - The zona zip is the mod (or 19" wheeled for those of you who don't know it yet) and the zona zenith stock bike (26") Yes the frame names do both begin with Z's like the company Zona use already existing frame designs and tweak them to improve them. This, along with alternative maufacturing methods + materials is probably why they are so cheap. So in essence. Onza do help their sister company zona out, but zona is a DIFFERENT brand to onza. Think of it as tensile + onza (I know its not the same but as an example) What frames do you know that are manufactured by tensile? OK that should avoid any unessecary confusion now. If I've made a blunder Ill edit it
