Brick Bashers were designed to allow skater to ride the rough surfaces. These wheels are 82A Durometer with a harder inner core that allow them to perform like harder wheel with a softer riding surface. If you haven't riden these you will be amazed at how they feel soft and smooth but are still responsive like harder wheels. These wheels are great for a cruiser setup or for skating rough ditches or spots that were previously not skateable. We are proud to offer these as they allow people to skate almost anything. Like all our wheels, Brick Bashers are made in the USA from the finest urethane. If you skate lots and love to skate, you have to try the Brick Bashers. They make almost anything skateable.
