Core: Morph-Wing™ Core
Introducing the Morph-Wing Core: Your Shot, Transformed.
The Morph-Wing Core is a dynamic, unique shape that changes more than any other core in the industry when drilled.
It all comes down to controlled weight shift: when your pro shop drills into the core’s "wing," the internal weight changes dramatically. This shift greatly transforms the core numbers, giving you a completely different flare pattern and motion that no other asymmetric shape can match.
The Power of Two Shots in One: The core design allows you to unlock two totally distinct performance profiles for traditional thumb players.
The HP5 line represents Roto Grips commitment to pushing the boundaries of bowling ball design. Reserved for our most advanced innovations, the HP5 is dedicated to one thing: REVOLUTIONARY PERFORMANCE.
The Morph-Wing Core is a dynamic, unique shape that was built to enhance torque induced precession when drilled.
Image Sequence
Engineered to change drastically when drilled
Displacing mass in the wing section fundamentally alters core numbers
Unlocks completely new flare potential and ball motion
WHY IS THE MORPH-WING CORE UNIQUE?
TORQUE INDUCED PRECESSION
Torque induced precession pulls the ball in the direction of the center of mass. This can cause a ball to retain or lose axis rotation faster on the lane.
It all comes down to CONTROLLED WEIGHT SHIFT: when your pro shop operator drills into the “wing” the internal weight changes dramatically.
This shift greatly transforms the core numbers, giving you a completely different flare pattern and motion that no other asymmetric shape can match.
TORQUE INDUCED PRECESSION IS
TRUE GYROSCOPIC PRECESSION
Torque induced precession is true gyroscopic precession. It has a huge influence on the rotation of a bowling ball. This happens because angular momentum chases the torque created by the center of mass.
TORQUE INDUCED VS TORQUE FREE
ROTATIONAL INFLUENCE
Torque induced precession pulls the ball in the direction of the center of mass. This can cause a ball to retain or lose axis rotation faster on the lane.
WINGS ARE THE KEY TO TRANSFORMATION
Dynamic asymmetric design that physically transforms when drilled
Mass displacement in the wing creates unprecedented core number changes
Delivers completely different flare patterns and motion based on drill transformation
Most transformable core shape on the market
PIN DOWN REVOLUTION
“Pin down layouts increase intermediate differential more than traditional designs, giving you a stronger overall motion with control.”
