Retro RG Spare Ball 16lb

Roto Grip Retro RG Spare Bowling Ball

When filling frames matters, the Roto Grip Retro RG Spare gives bowlers a durable, predictable option built specifically for spare conversions. Combining a Traditional 3-Piece Core with Roto Grip’s High-Impact™ Pearl Urethane coverstock, the Retro RG Spare is designed to provide the controlled, straightforward motion needed when accuracy is the priority.

At the center is the Traditional 3-Piece Core, one of bowling’s simplest and most proven core constructions. Its pancake-shaped puck creates an end-over-end tumbling motion, helping produce the predictable trajectory bowlers want when shooting spares.

What separates the Retro RG Spare from a traditional plastic spare ball is its High-Impact™ Pearl Urethane coverstock. Developed using highly durable polyurethane components, the material is engineered for increased structural tensile strength and toughness. Its natural elasticity allows the cover to flex when subjected to stress and impact rather than responding like traditional plastic, which can be more susceptible to chipping or cracking.

The result is a purpose-built spare ball that combines predictable motion with exceptional durability—ideal whether you're replacing a worn-out spare ball or adding your first dedicated spare option.
