When showering after a long ride, you leave bike grease on your inner calves because to you it looks tuff and pretty all at once. Or maybe it makes you feel tuff even though it's not pretty.

You find yourself exchanging graphic stories re: the condition of your private parts with your other riding friends, both male and female. At dinner no less.

Already mentioned but also applies to me:

You buy mediocre wine that's not even all that great because the label has a bike on it.

Your dog knows when you're leaving to ride and throws a suitable fit because he knows you will be gone awhile. It must be the spandex.

You strut into work in the morning hair sweaty and smashed, spandex flaring.
