Roto Grip Gremlin Tour X Bowling Ball – Tour-Level Asymmetric Hybrid Ball

Precision-Engineered for Tour-Level Control

Looking for an asymmetric hybrid bowling ball that delivers professional-grade control and predictability? The Roto Grip Gremlin Tour X is engineered for bowlers who demand enhanced control and consistent motion across the entire lane. This ball combines advanced core technology with a balanced hybrid coverstock, giving you versatile, tunable performance that works on various oil patterns — making it a valuable addition to any competitive arsenal.

Rondure™ TOUR-X Core – Precision Modification

At the heart of this ball is the Rondure™ TOUR-X Core, a precision-engineered modification of the proven Rondure shape. Roto Grip engineers manipulated the internal mass densities to lower both the Radius of Gyration (RG) and the Differential, intentionally redesigning the core for better control.

Lowered RG and Differential for Control

What do lowered RG and Differential mean for your game? These lower numbers create:

• Highly controllable motion that’s easy to repeat
• Smooth, predictable arc through the lane
• Medium-flaring dynamics without excessive hook
• Consistent reaction shot after shot

Lower RG means the ball revs up in a controlled manner, while the reduced differential creates medium flare instead of high flare. You get power without unpredictability — the ball hooks plenty but stays controllable.

Medium-Flaring Asymmetric Design

The core delivers a medium-flaring asymmetric dynamic that hits the sweet spot for competitive bowlers:

• Asymmetric shape provides more dynamic motion than symmetric cores
• Medium flare offers control that high-flare cores lack
• Balanced dynamics that work for a wide range of bowling styles
• Versatile performance across different conditions

You get enough dynamics to create angle without the excessive over/under reaction that can plague higher-flaring equipment.

V-R1™ Hybrid Reactive Coverstock

The V-R1™ Hybrid Reactive coverstock is an advanced, nano-free formulation designed for an aggressive footprint on the lane while balancing strength with predictability.

Advanced Nano-Free Formulation

The nano-free formulation takes a different approach from many modern coverstocks, delivering:

• Clean, predictable traction without nano particles
• Consistent reaction across different lane surfaces
• Traditional performance that’s easy to read
• Reliable motion bowlers can trust

Nano-free doesn’t mean less performance — it means performance achieved through different technology, with a coverstock that’s easier to maintain and predict.

Precisely Engineered 2:1 Ratio

What makes the V-R1 Hybrid special is its precisely engineered 2:1 ratio — blending two parts solid with one part pearl. This carefully calculated blend creates a unique balance of properties:

• Maximum mid-lane traction from solid components
• Backend response from the pearl additive
• Potent balance of power and predictability
• Aggressive footprint on the lane

The solid components ensure a strong read through the middle of the lane, giving you excellent control on medium-heavy oil and predictable motion that builds momentum. The pearl component prevents the ball from hooking too early while ensuring strong backend motion for impressive pin carry. You get the best of both worlds — solid control with pearl continuation, and consistent, continuous motion instead of sharp angles or rollout.
