Is there a tell-tale sticker or serial number code that can be parsed to tell if a frame is intended for men or women? Basically, can I take a serial number sticker and lookup somehow what physical sex it was designed for?
As an example if you consider the following bike search for a
Trek Chronus and search the hits for women you'll find 2 hits. At first glance they don't stand out all that much from all the other frames besides them, so I'm wondering if I were faced with buying a used one, how could I tell which bucket it landed in?
