Well I dont know a massive amount about different trials brands, coming more from mountain biking, but as far as I gather there's a guy called Deng Qiang who owns loads of different companies. The companies make frames and components that range from looking similar, to identical to one another other. Well, the frames are mostly different, but if you look down tartys' rear hub section, theres the exact same hub with Adamant, echo, Czar, Gu, and Zoo! written on it. Same with headsets and other stuff. Why cant he just stick with one brand to make stuff under? I understand why someone would want a Echo hub to go with their shiny new Echo frame or something, but why so many different bike companies? Not that theres anything wrong with it, just something I was wondering about.
