The Dynasty III wheel features 3 layers of hardness
Outer urethane layer is soft for maximum grip
Inner urethane ring: Ring works to react and spring back under different stride loads; provides unmatched straight away speeds while producing energy in the tightest corning
Flex core urethane allows the wheel to flex to maximize the outer layer's footprint (contact with the floor) and spring back at its designated points
Fast, narrow high-performance profile
