95a urethane durometer
95a is dreads hardest option and generously drifts on rough ground. It is tailored for flat, street skating setups where one wants to sacrifice grip for friction reduction while grinding or sliding.
Due to its hardness, this 95a has very little to no grip in dusty skateparks.
58mm wheel diameter
DEAD have 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. They developed this unique rounded profile to provide a natural feeling of fluidity while rolling and turning.
