While many people might update their Facebook profile, Profile Design’s RZ2 frame-mounted bottle system will help improve the profile of a bicycle – and even improve the aerodynamics in the process. This 14-ounce bottle features a contoured shape with recessed hand grips, integrated cap that twists off for easy cleaning, an injection composite cage and is BPA free. It mounts to standard bottle cage bosses and weighs 141 grams.
