BMX parts company Odyssey have been developing these new type of pedals and saddles which are not functional improvements but definitely fun and original. The Twisted PC pedals and Senior 2 Pivotal saddles are the models that got the Chameleon treatment and they are specially formulated to react to UV rays (sun light) and change color. Under non UV light the parts are opaque milky white color or skeleton like. When they are exposed to the UV rays, it changes color to either purple, red, yellow, pink or blue in a fairly solid color. These are made for BMX's however they will also fit on regular bicycles or fixed gear bicycles. Currently available through Odyssey's online store and authorized dealers around the world. View the videos below to see how they change colors under different lighting conditions.
