ADJUSTMENT PERIOD & COMPATIBILITY
The rounded finish allows for use in competitions with a minimal adjustment time. In general, the softer the wheel (or the lower the “Shore” hardness number), the greater the grip and the slightly lower the smoothness. The harder the wheel, (or the greater the “Shore” hardness number), the greater the smoothness and slightly less grip.
