Hammer Black Widow Spare+ Bowling Ball

The Hammer Black Widow Spare+ combines precision spare shooting with one of the most recognizable core designs in the Black Widow lineup. Featuring the legendary Gas Mask asymmetric core paired with a Polyester coverstock, the Black Widow Spare+ delivers a straight, predictable reaction designed to help bowlers maintain accuracy and control when shooting at spares.

Finished with 500, 1000, 2000 Siaair / Factory Polish, the Black Widow Spare+ minimizes friction and unwanted lane response, making it ideal for spare shooting and light oil conditions. In 14–16 lb weights, the Gas Mask core provides substantial differential and asymmetry, giving Black Widow fans the familiar core technology they know while maintaining the controlled reaction expected from a polyester spare ball. Its clean White Diamond appearance completes a distinctive spare option built for precision.
