BANDIT™

Sword Line

Anchoring the Nomad™ series, the Rotary™ weight block made its way into the starting lineup for many tour players. Like Wes Malott, many PBA members love its strong, predictable motion across a variety of oil patterns.

In designing the Outlaw and Bandit, our goal was to create a completely new weight block shape which maximizes pin action, accomplished through increased energy transfer(testing showed an increase of 12% when compared with a traditional core design), and works for both rev dominant and speed dominant players alike. The new Caliber™ weight block does just that!

In addition, we created a new coverstock blend called Inception™ which proved itself right from the outset, hence the name. The surface topography showed Ra values up nearly 10% from previous blends. The highly polished Bandit and 2000-grit Outlaw both handle a variety of conditions ranging from a typical house shot to tough tournament action. When you're looking for "long and strong" pick the Bandit. The Outlaw will be there when you need an earlier, more predictable reaction.

Put it all together and you have two flawlessly-designed weapons that are a MUST for any arsenal!

ROTO GRIP – it's all about the ATTITUDE.



CRITICAL THEORY™

Crown Line

So how exactly do we improve and expand upon already proven performance like that of the Infinite Theory?

Remember that ball motion is a culmination of the numerous factors like coverstock material, surface texture, porosity, weight block dynamics, layout, etc. When considering all of these variables, it is truly a technical feat to be able to balance all of these items and produce a bowling ball that meets the high standards you've come to associate with Roto Grip.

With the new Critical Theory, we are expanding the Theory series with its first pearl Insight™ coverstock. Designed to maximize dry lane traction, this shell will help increase your entry angle and sharpen your break point (CATS testing proved that the Critical Theory created the most entry angle in the entire product line), all in an effort to help you strike more! Its textured 4000-grit surface increases the Ra value, minimizes oil sensitivity, especially at the end of the oil pattern, and maximizes your bowling enjoyment.

Wrap the new textured pearl Insight cover around the high-torque, asymmetrical Triliptic core and you have some horsepower. Drill your new Critical Theory with your favorite layout, throw it at the dry boards to the outside, and watch it charge back with authority.

DEFIANT™

Royal Line

Release Date - January 10, 2012

At Roto Grip, we rule the lanes! And you better have your game in gear if you want the same.

Starting at the center, the "GUTS", the new Paragon™ core features contours designed to help expand the RG planes of the ball. This unique elliptical shape defines predictability of axis migration and allows you to perfectly match up your ball reaction to the condition at hand. Strong midlane roll and a HUGE continuous, sweeping hook on the backend! This is a serious technological advancement.

Moving on to the shell, the "GRIT", we've developed a new MicroBite™ coverstock that is stronger and more textured than the competition. Microtechnology, the use of extremely-small structured additives down to a millionth of a meter, makes this possible. When finished with 3000-grit Abralon®, this new MicroBite shell creates friction where others just cannot!

And finally, looking at the "GRIME", the designated oil pattern and lane condition, the Defiant is sure to handle even the heaviest amounts of oil. Today's lane oils have more solids than ever before, making the lanes very slick at times. With the new Defiant, no more worrying about heavy oil often found on tournament shots! Roto Grip has you covered.

GRENADE™

Shield Line

Intent

Our goal was to expand the Shield™ line and complement the Dark Star™, Riot™ and Mars™.

With products built on the premise of value and performance, the Shield line offers an array of choices, each with a distinct ball motion. From medium-dry lane conditions to medium-heavy, there is a ball in the Shield line that fits your needs.

The modern bowling environment can produce violent ball reactions with even mild reactive coverstocks like Sure Grip II™. Often we have high friction lane surfaces, short oil patterns and squeaky clean backends. While the Mars is a terrific choice for medium-dry conditions, power players and traditionalists alike demand even MORE control and predictability. Control the uncontrollable with our new Grenade!

Design

At Roto Grip® we pride ourselves in providing a complete line of bowling balls in both value and performance.

With a medium RG (2.58) and medium differential (.040), the Photon ™ core utilized in both the newly released Riot and Dark Star, is the perfect foundation for the new Grenade.

You know that the coverstock is critical to ball motion, so even when testing on a shorter oil pattern, even a milder version of Sure Grip II with the Photon core was too much. We decided to step it down a notch and go 'Old School' with the new Retrothane™ shell because predictable ball reaction never goes out of style!

The Retrothane is a traditional urethane coverstock that will help you tame even the most scorching lane conditions. As witnessed on the PBA Tour and in World Championship events, urethane is still effective today. Redefine your arsenal with the new Grenade and know that no matter what they throw at you, Roto Grip has you covered.

Roto Grip – we're pulling the pin, tossing the Grenade and shaking it up.

INFINITE THEORY™

Crown Line

Intent

By now you have probably experienced the tireless power of the original Theory™. With the intense Insight™ reactive coverstock and Triliptic™ core, the Theory hit the market and immediately made a huge impact. And with the prior success of the Cell™ series and original Nucleus™ core shape, it was clear that the Theory had some big shoes to fill.

With the solid Insight cover, the Theory created a tremendous amount of hook in oil. In fact, it was borderline criminal! But some bowlers were looking for a smoother glide through the heads with a strong motion through the pocket, so here is where the new Infinite Theory comes into play.

Design

You might recall the new Triliptic core helps the ball get into a roll easier due to the additional contours and elongation of the ellipses within the shape of the weight block. The Infinite Theory's triple elliptical shape creates consistent axis migration and predictable ball motion, a must for consistency.

Consider as well the resilient outer core which minimizes the energy absorption upon impact at the pins. What this means to you is that you are now getting more energy transfer from the ball to the pins, increasing your pin movement which ultimately results in more strikes.

In addition, the innovative Insight™ coverstock has expanded surface roughness while the Infinite Theory's hybrid blend gives you added versatility. The Infinite Theory comes highly polished to float effortlessly through the heads, but with just touch of Abralon® you will also reap the benefits of a solid.

Roto Grip – it's all about the ATTITUDE.

MONARCH™

International Balls


Design

At Roto Grip, we pride ourselves at giving you the equipment you need to be ready to take on all competitors. Roto Grip's kingdom NEVER turns down a challenge or gets disrespected on the lanes.

One such proven design creates the perfect blend of power and predictability. The CAM™ core, which powered the United and several other Royal Line balls, offers a mild asymmetry which produces a short, arcing breakpoint shape that works across a wide range of conditions. The high total differential produces more axis migration and total hook, just what you've come to love with the Royal Line. So it comes down to this: the CAM core gives you confidence needed to excel.

Looking at the shell, the Armor™ base material has proven itself through several previous launches including the Kingdoms and more. So, we chose the highly polished Armor hybrid reactive cover to complement this popular series.

At Roto Grip, combining solids and pearls have been extremely popular due to the unique ball reaction that is created. It gives us the ability, whether you're a stroker or a cranker, to match break point shapes with your style. And remember to fine tune the performance of your new Monarch with Abralon®. This is one of the final key steps to help you take control of the lanes.

Roto Grip – KING OF THEM ALL!

OUTLAW™

Sword Line

Anchoring the Nomad™ series, the Rotary™ weight block made its way into the starting lineup for many tour players. Like Wes Malott, many PBA members love its strong, predictable motion across a variety of oil patterns.

In designing the Outlaw and Bandit, our goal was to create a completely new weight block shape which maximizes pin action, accomplished through increased energy transfer(testing showed an increase of 12% when compared with a traditional core design), and works for both rev dominant and speed dominant players alike. The new Caliber™ weight block does just that!

In addition, we created a new coverstock blend called Inception™ which proved itself right from the outset, hence the name. The surface topography showed Ra values up nearly 10% from previous blends.

RISING STAR™

Shield Line

Roto Grip® is committed to bringing you a wide variety of performance in the product line. When you throw Roto Grip know that you always get a tremendous value whether you choose a high-end Crown™ line ball like the wildly aggressive Theory™ or something more subtle and tame like that found in the Shield™ line.

Our intent with the new Rising Star was to create a ball that works well on medium-light oil patterns for bowlers of different skill levels and styles. With the benchmark-type symmetrical core shape, the original Dark Star™ was the cornerstone of the Shield line in 2010, and the new Rising Star will fit the same parameters and perform even better.

To increase total hook as compared with the Dark Star, the Ultimate Vision™ hybrid coverstock is a must for this new release. It creates a smooth glide through the heads with ample bite on the dry boards without being over-sensitive. And with a 1500-grit polished finish, the new Rising Star is sure to raise the bar.

A journey to the center of the ball will reveal the new Neutron™ core as the power source. The Neutron core's medium RG- medium differential shape is based on the concept started with the original Photon™ core utilized in the Dark Star. But you'll find an even lower RG and higher differential in the heavier weights. So look for more motion out of the Rising Star with all the benefits of a hybrid coverstock.

As you rise to the top with this new Roto Grip release, you'll quickly see why it earned the name Rising Star!

ROTO GRIP – it's all about the ATTITUDE.

SHOOTING STAR™

Shield Line

Design

With the phenomenal success of the original Rising Star™, the Shooting Star™ must utilize the new Neutron™ core as the power source. It's just that good!

The Neutron core's medium RG- medium differential shape is based on the concept started with the original Photon™ core. But with the Neutron core, you'll find an even lower radius of gyration (RG) and higher differential in the heavier weights which hooks up heavy on the backend.

To increase the midlane roll and bring an earlier break point, we looked at a few different options. Testing the Ultimate Vision™ coverstock in a solid version produced the desired motion. Prepped with 2000-grit Abralon®, the Shooting Star created a break point that was two feet earlier and more rounded, or smoother. Controlling the pocket is often the key to higher scores. Shoot for higher scores with the new Shooting Star.

ROTO GRIP – it's all about the ATTITUDE.

STAR ALLIANCE™

International Balls

Design

At Roto Grip, we rule the lanes, and we want you right there with us! As we designed the new Star Alliance, we considered first the core and then the coverstock. Some balls in the Royal line are built on a mild asymmetrical platform like the C.A.M. ™ core design to balance transition and entry angle. Since we are looking to maximize backend reaction, the more dynamic, proven Pinnacle™ core is just what the doctor ordered.

As you know, coverstocks can be either solids, pearls, or combinations of the two, also known as hybrids. Maximum flip calls for a pearl mixture and, when polished to a smooth 1500-grit, the Armor™ coverstock clears the heads with ease and allows for more reaction at a later break point. The Star Alliance's shell can easily be manipulated if you need to adjust the motion. It readily accepts your favorite surfacing pad or polish.

Most importantly, know this: Roto Grip manufactures to the highest standards, and that when you choose Roto Grip you are one step closer to becoming 'king of them all! ™ '

Roto Grip – KING OF THE LANES.

TECHNO THEORY™

International Balls

Design

If you are looking for high performance, think asymmetrical shapes and powerful coverstocks. As we are working to develop this new Techno Theory, our new high performance release, we will utilize the dynamic Triliptic™ core as it helps the ball get into a roll easier due to the additional contours and elongation of the ellipses within the shape of the weight block.

But that's not all that makes it special and unique. The Triliptic core features an energy efficient outer wrap that increases your pin movement and energy, producing better pin action and strikes. And who doesn't want that?!

To accentuate the dynamic core, we wrapped it with a straight pearl coverstock which gives you maximum response to the friction. And to create the most angle into the pocket, we polished the Insight™ pearl reactive coverstock it to a gleaming 1500-grit finish. The combination creates ultimate performance to help you master the deep inside line and you move inside, swing out and watch it come dancing back to the pocket every time.

ROTO GRIP – It's all about the ATTITUDE.

WORLD ALLIANCE™

International Balls


Design

At Roto Grip, we rule the lanes! You need the best equipment available if you want to do the same. So as we designed the new World Alliance we looked at the key factors like coverstock, surface preparation, and mass properties of the weight block and created a combination which we are sure will be appreciated across the globe!

Some balls in the Royal line are built on a mild asymmetrical platform like the C.A.M. ™ core design to balance transition and entry angle. The new World Alliance will step on the gas pedal a bit with the more dynamic, proven Pinnacle™ core to help increase entry angle.

When polished to a smooth 1500-grit, the resilient Armor™ coverstock clears the heads with ease, reducing the coefficient of friction values. Since this means that the ball loses speed slower, you're sure to see a more powerful impact at the pins. And the hybrid version found here gives the later breakpoint without being oversensitive to drier portions of the oil pattern. Put it all together and you're ready to take on the world!
