And don’t worry, the High-Impact Pearl Urethane is as durable as durable can get. Truth is, you will likely get tired of it, long before it gets tired of you.

We present to you most basic and simplistic core shape known to mankind, the Traditional 3-Piece Core which features a pancake shaped puck at the top which provides an end over end tumbling effect thus making this the ideal core for spare conversions.
