Let's face the facts. Like most sports, cycling is primarily dominated by men. In my experience, this has rarely been an issue of contention—something I attribute to the general awesomeness of the dudes I ride with. However, there have been occasions, in less awesome company, where my lack of male genitals has been an obvious bone of contention. Unless you know better, never assume we are slower, weaker or unable to change our own flat. And unless you are the person lucky enough to share our bed, never, never, tell us how nice our ass looks in our bike shorts. A good rule of thumb: If you wouldn't say it to a guy, don't say it to her.
