Hammer Black Widow Spare+ (Pre-Order)

Pre-Order Expected to Arrive Sep 17, 2026

Not every polyester ball is created equal. The Hammer Black Widow Spare+ pairs the iconic Gas Mask core with a polyester cover to create a uniquely versatile bowling ball. It delivers the accuracy bowlers demand for spare shooting while offering enough core dynamics to become a valuable option on extremely dry lanes, and shorter patterns with less volume. Whether it’s used for converting corner pins or helping you navigate the toughest lane conditions, the Black Widow Spare+ is ready for the challenge. Wrapped in a striking white pearl finish with eye-catching sparkle, it’s every bit as bold as the Black Widow name deserves.
