I met carolyn at the March sunday streets and was drawn to her cool rig. on closer inspection i found that not only is she a true bike person, as indicated by the iconoclast of her easy spirit sneakers and her bike's chain ring drillium, but that she is also a fashionista. She knit both her amazing and stylish sweater, and her partner Keith's vest. I think that this couple owns SF pedicab- bike people to the core!
close up of the drillium, or holes drilled out so that weight can be shed while strength and integrity maintained.
