For 2008 the Zero Gravity folks from Athens, GA have added the Negative G brakes to their arsenal of light weight goodies. More oversized and rigid caliper arms are mated to the Ciamillo Power Cam and feature a 2.85:1 mechanical advantage. The Ti version pair weighs 196 grams without pads and the SS pair weighs 214 grams without pads. Either set though will allow you to shave a significant amount of weight from your road or triathlon bike.
