Smooth? Chunky? Why not both! The Piper Chunky Wheels are made for outdoor skating, featuring durable, high-quality urethane hand-poured right in the U.S. 78A hardness keeps things rolling smooth yet grippy, whether you're rolling sidewalks, hitting trails, or cruising the boardwalk. Large 61mm diameters provide sustained rolling power, and a generous 32mm width keeps things feeling stable so you can stay balanced and enjoy the ride.
