so my girlfrind has what looks like a '99 hardrock sport that is brandnew. It appears to have a 1-1/8 threaded steerer. Its too fat to be a 1inch, unless the headtube is rediculously thick. first question, does what i'm talking about even exist, and second, can i press it out and put a regualr 1-1/8th threadless headset in?
