What if your wheels could be reincarnated? Product specialists at POWERSLIDE worked for hand in hand with MATTER urethane experts to develop a new concept of inline skating wheels that could help reduce environmental impact. The UC Earth 60mm wheels are made of Eco polyurethane which is 15% corn-based and features a natural milky look that avoids the use of additional color pigments. The reflex hub is made of 40% recycled material. The round profile and the 88A hardness complete the specs to make it one of the first eco-friendly wheels.
