And what if your wheels could be reborn? The engineers at our POWERSLIDE office in Bindlach have worked hand in hand with the urethane specialists from MATTER to develop a new concept for roller skate wheels that could help reduce environmental impact. The UC Earth wheels, with a diameter of 110 mm, are made from eco-polyurethane, which is 15% derived from corn, and feature a natural milky appearance that avoids the use of additional colored pigments. The reflex hub is made from 20% recycled material. The speed/ball profile and hardness of 88A complete the specifications, making it one of the first eco-friendly urban wheels.
