Hammer Black Widow Urethane Bowling Ball Features:

The Black Widow Urethane combines a solid urethane coverstock with what is arguably the most popular core design ever from Hammer. The high-flaring Gas Mask core is unchanged from the other Widow line releases, with an RG of 2.50″, a total differential of 0.058″, and an intermediate differential of 0.016″. The dull urethane cover on this ball is earlier and smoother than the React-a-Thane cover from the Burgundy Hammer from several years back, but the added flare will offer more motion at the breakpoint than the Performance Urethane cover that was used on the Blue Hammer. The sanded 500 Abralon box finish makes sure this ball creates traction early on the lane so it doesn’t skip past the breakpoint.

In the 1980’s, Hammer was known as “Faball Enterprises” and was the industry leader in urethane technology and performance. Over the past few years, we have gone back to our roots and brought back the Black and Purple Pearl Urethane. Hammer is excited to bring this same trusted urethane formula to the Black Widow line and wrap it around our most iconic core. This combination will give you more overall hook than traditional urethane while maintaining the predictability that a urethane coverstock provides.

    The Hammer Black Widow Urethane has the hit power of your reactive resin bowling ball! The Gas Mask Core allows some versatility with this bowling with the high flare potential. It has great midlane read and the hook a bowler is looking for! In my opinion, this ball is ideal for bowlers with high ball speeds where the Purple and Black Urethane does not have a stronger backend motion. However, this ball is still very clean and continous, what you expect from a urethane ball and a great compliment to the Purple Urethane.
