So? Steel bends and it's just as useless. And I think you're forgetting that mountain bikers, particularly freeriders and downhillers, are MUCH harder on their sh*t than BMXers, and there's a fair amount of plastic on those bikes nowadays. The only difference is that steel and aluminum are cheap to replace.
