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 specifically for bowlers seeking enhanced control and consistent motion across the entire lane. In fact, this ball combines advanced core technology with a balanced hybrid coverstock. As a result, you get versatile, tunable performance that works well on various oil patterns. Moreover, it’s designed to be 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. Specifically, Roto Grip engineers manipulated the internal mass densities to create specific performance characteristics. As a result, they successfully lowered both the Radius of Gyration (RG) and the Differential. In other words, the core was intentionally redesigned to provide better control.

Lowered RG and Differential for Control

First, let’s talk about what lowered RG and Differential means for your game. Specifically, these lower numbers create:

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

Moreover, lower RG means the ball revs up in a controlled manner. Additionally, the reduced differential creates medium flare instead of high flare. Therefore, you get power without unpredictability. In other words, the ball hooks plenty but stays controllable.

Medium-Flaring Asymmetric Design

Next, the core delivers a medium-flaring asymmetric dynamic. Specifically, this is important because:

• Asymmetric shape provides more dynamic motion than symmetric cores
• Medium flare offers control that high-flare cores lack
• Perfectly tuned for smooth, professional motion
• Balanced dynamics that work for more bowling styles
• Versatile performance across different conditions

Additionally, medium flare is the sweet spot for many competitive bowlers. In fact, you get enough dynamics to create angle without excessive over/under reaction. Therefore, the ball is easier to control while still performing powerfully.

V-R1™ Hybrid Reactive Coverstock

Next, the V-R1™ Hybrid Reactive coverstock is an advanced, nano-free formulation. Specifically, it’s designed for a more aggressive footprint on the lane. Moreover, this coverstock uses a precisely engineered approach that balances strength with predictability.

Advanced Nano-Free Formulation

First, the nano-free formulation is worth noting. Specifically, many modern coverstocks use nano-technology. However, the V-R1 Hybrid takes a different approach. As a result, you get:

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

Moreover, nano-free doesn’t mean less performance. Instead, it means performance achieved through different technology. Therefore, you get proven results 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. Specifically, this means blending two parts solid with one part pearl. In other words, the coverstock is mostly solid with pearl characteristics added. As a result, you get a unique balance of properties:

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

Additionally, the 2:1 ratio is carefully calculated. In fact, this specific blend creates the perfect balance between traction and length. Therefore, you get consistent, continuous motion instead of sharp angles or rollout.

Solid Components for Mid-Lane Traction

First, the two parts solid ensure maximum mid-lane traction. Specifically, this means:

• Strong read through the middle of the lane
• Excellent control on medium-heavy oil
• Predictable motion that builds momentum
• Consistent traction across different surfaces
• Reliable performance shot after shot

Moreover, mid-lane traction is crucial for control. In fact, balls that read the midlane well are easier to control and more predictable. Therefore, the solid components create the foundation for professional-grade motion.

Pearl Additive for Backend Response

Next, the one part pearl provides backend response. Specifically, this addition creates:

• Clean length through the front of the lane
• Strong continuation at the breakpoint
• Backend energy for pin carry
• Angular motion when needed
• Versatile reaction across conditions

Additionally, the pearl component prevents the ball from hooking too early. Furthermore, it ensures strong backend motion for impressive pin carry. As a result, you get the best of both worlds—solid control with pearl continuation.
