88a urethane durometer
88a is our lowest durometer urethane, providing the maximum amount of grip and control. This wheel holds very well in sharp turns and is a great option for skating smooth wood, metal or concrete skateparks. On rougher surfaces, these wheels can wear down quickly. When riding with 88a wheels in the middle, make sure the frames have enough wheel bite protection, as they can stop you from sliding.
58mm wheel diameter
We found that 58mm is the best size for all around street and park skating. It is small enough to keep you close to the ground, and stay out of the way while grinding, yet large enough to last you while skating rough surfaces in the streets. We developed this unique rounded profile to provide a natural feeling of fluidity while rolling and turning.
