My goal is to take my Specialized Sirrus Limited and make it into the world's fastest, baddest city/commuter/recreational ride. So far, I've changed the stem to one that is a bit longer, added the Shimano SPD pedals, Garmin 500 (pic shows my old iPhone mount), and the ToPeak rack.
Next on the list is a bit fatter tires (28mm from 23mm) with something that has a bit more tread pattern.
