Our intent was to design a pure urethane coverstock with less surface friction for those challenging patterns along with a core combination that would complement. We developed the U2S coverstock, a second generation of U2000. It enables one to get length with out the over-reaction that resin sometimes creates.
Even though it's made of a pure urethane material it's dynamic enough to handle today's lane conditioners. The Turbine core creates ample flare to ensure fresh coverstock is always touching the lane. This translates into additional friction to create ample entry angle, without generating an over/under reaction down lane. The Natural integrates classic reaction with today's modern technology to deliver unbeatable performance.
