> Does anyone else have an "industry" definition? Those definitions from Bicycling would be the opposite of what I was taught but consider this bit of info from the automotive world:
A two wheel drive car has front and rear axles (well so does a four wheel drive car but that won't help me make my point). At the end with the driven wheels, what we call the axles rotate with the wheels in order to propel them. At the other end, the axles are stationary in their uprights and the wheels rotate around them. Yet they're both called axles in general parlance. So it seems to me that, with this subject, you simply can't be punctilious in your usage. Unless (to paraphrase Woody Allen) you're like trying to be like didactic.
