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.
