What if your wheels could be reincarnated? we worked hand in hand with engineers and urethane specialists to develop a new concept of inline skating wheels that could help reduce environmental impact. The UC Earth Project wheels are made of Eco polyurethane which is 45% corn-based and features a natural milky look that avoids the use of additional color pigments. The reflex hub is made of 100% recycled material. The speed/bullet profile and the 88A hardness complete the specs to make it one of the first urban eco-friendly wheels.
