There are plenty of men who are recreational cyclists who also could not tell you much about their bikes beyond the color. Some people take their cycling seriously and do their homework to find the best bike for them that they can afford. Others just pick up a Wally World bike and ride. And some are in between. They buy from the LBS, but still don't really know much other than whatever the sales person emphasized. For example, my husband knows he has disk brakes. He couldn't tell you whether they are hydraulic or mechanical, what chainrings and cassettes he has or how wide his tires are. He knows he has presta valves (but can't remember that name) only because we had to buy a new pump.
