The Roto Grip Transformer bowling ball offers great versatility through its innovative Morph-Wing™ Core design. As a result, this unique core gives bowlers complete control over ball motion. Furthermore, it allows drillers to change the ball’s reaction based on thumb hole placement relative to the precession wing.
Morph-Wing™ Core Technology
The Transformer’s advanced core creates predictable, repeatable ball motion matched to your bowling style and lane conditions. Specifically, drilling placement—either through or away from the precession wing—changes how the ball reacts downlane. Consequently, bowlers can adjust their equipment to fit almost any situation.
Pin Up Layout (Traditional Thumb Bowlers)
When placing the thumb hole away from the precession wing, several benefits occur:
First, it helps the ball hold its axis rotation for steady performance
Additionally, it creates stronger backend motion with a sharper entry angle
Therefore, this layout is ideal for open angles and changing lane conditions
Pin Down Layout (Traditional Thumb Bowlers)
In contrast, drilling the thumb hole through the precession wing creates a different reaction:
Initially, it produces an earlier, smoother hook with a rounder shape downlane
Moreover, it boosts asymmetry and ball dynamics
As a result, this layout works best for straighter angles and fresh oil patterns
Two-Handed Bowler Layouts
Similarly, two-handed bowlers can adjust their ball reaction through smart drilling choices:
Pin-to-COG 3½” to 5½” (through precession wing): This setup results in earlier, smoother motion with better control
Pin-to-COG under 3½” or over 5½” (missing precession wing): Alternatively, this setup provides cleaner length with more angular backend
V-R1™ Solid Reactive Coverstock
In addition to its advanced core, the Transformer features Roto Grip’s V-R1™ Solid Reactive cover. This nano-free material is designed for balanced traction and reliable reaction. As a result, bowlers get steady performance across different oil conditions.
