My road ID arrived in the mail yesterday.
Ever since I started hearing the stories about accidents and seeing pictures of dented cycling helmets, I'd been thinking about getting one of these.
I chose the ankle style instead of the wrist because I guessed (and was correct) in noting from the pictures that it might also hold a timing chip.
The metal plate has six lines in which information can be etched, and the white band on the velcro is reflective. They come in red, blue, and black, and you can also get them in wrist bands, "dog tags," and a little pocket that fits on your shoe.
I feel safer already!
