Feels unlike any Labeda wheel made to date. The wheels fuses together two very distinct and unique urethanes creating one incredible ride. It starts with a large, hard urethane disc that provides a very thin , hard wheel feel with extreme stability. You actually feel like you are skating on the thin inner disc. Secondly, our newly developed outer urethane formula provides unmatched wear resistance. If you want a lighter, faster, better gripping and wearing wheel, you just found it!!! (Available in X-Soft 80, 76 & 72mm)
