The next generation of urethane starts with MicroCell Polymer in the Motiv Covert Tank!
The Frixion coverstock delivers a new, more versatile motion for lower rev rate bowlers with this microcell polymer chemistry. This allows for minimum oil redistribution, but maximizes backend movement and track flare.
Combined with the Torx Symmetric weight block, the Covert Tank gives easy revs after gliding through the heads to deliver great motion and pin carry in the backend.
Here's what Motiv has to say about Covert Tank:
A great competitive advantage in bowling today is modern urethane. It provides bowlers with control and the ability to play different parts of the lane than reactive resin. However, because urethane also has clear weaknesses, MOTIV® set out to create the ultimate cover material that harnesses the strengths of traditional urethane, but offers far more versatility. Introducing the Covert Tank. This is a game changer!
