I eschew labels. I ride bikes, most of which are road bikes with drop bars and gears.
I ride a bike to work, but I do wear cycling specific clothing such as tight jerseys with back pockets, lycra pants and shorts with padding, and shoes with clips. I treat it like my daily workout, so I do sweat, sometimes a lot. Cycling specific clothing works better for this than street clothing.
I'm also very serious about cycling. Very, very serious.
