Roto Grip UFO Alert Bowling Ball

Our obsession with helping players of all ages and styles conquer various lane conditions while abiding to forthcoming governing rules, led to the development and creation of the asymmetrical E.T. Core (Equalizer Technology Core) which features built in cavities in order to increase weight displacement after drilling without a balance hole to increase overall ball motion.

The MicroTrax (Micro Nanoparticle Traction) Coverstock offers the optimum balance of midlane traction and responsiveness to friction thanks the blend of nanoparticles throughout the coverstock. This formulation maintains its surface profile texture longer to ensure you get maximum performance while displacing oil at an above average rate compared to other coverstock materials on the market today.

Assembled for every bowler in the universe, the UFO Alert is here to help you navigate those Medium to Medium/Heavy Oil Conditions with ease. No matter your style, no matter your rev rate, no matter your speed, the E.T. Core (Equalizer Technology Core) with its built in cavities, is sure to create great overall core motion every time due to the added mass displacement when drilled. And we can’t forget about the eTrax Hybrid Coverstock which is made of 2 parts pearl and1 part solid. This cover combination aids in creating plenty of responsiveness to friction down lane without being too angular. Thus, making this combination of core and cover one of the most ideal options ever created for most any house type oil condition on planet earth.

Roto Grip RST X2 Bowling Ball

Given the continued success of the RST X-1, we knew the next ball in the series using the Roto Star Tour Core was going to need a special coverstock wrapped around it as well. So, after countless tests involving multiple players of different styles, we determined that the eTrax pearl material gave us the type of reaction we were looking for, but we wanted something a little more while still using that same chemistry. So, the R&D team went to work changing the ratios and other variables until we settled in on the NEW eTrax PLUS Pearl Reactive formula that provides a larger footprint throughout the entire lane without reducing the responsiveness to friction down lane. Creating yet another viable pearlized coverstock option for the Roto Grip family of balls.

Professional bowlers like to see continuous motion down lane with minimal deflection as the ball enters the pocket due to their rev rates usually being on the higher side. This logic was the basis of development by the R&D team as they looked to create a core that would maintain dynamics after drilling in order to maintain a higher level of core torque down lane. The larger mass at the base of the core does indeed create that. Especially since when drilled, the thumbhole will always end up in the void area not really affect the bottom mass of the core. Thus, making this core a “Tour Level” type core design better known as the Roto Star Tour Core (RST Core).

Roto Grip Idol Helios Bowling Ball

The Roto Grip Idol is back, and this time its set to light up the lanes! Introducing the Roto Grip Idol Helios, featuring the proven Ikon core, wrapped in a new XtremeTrax™ Coverstock. This high performance bowling ball will be a great match up on medium to heavy oil patterns.

On the inside you will find the low RG, higher differential symmetrical Ikon™ Core made famous in the original IDOL™. But on the outside, it’s the coverstock of this ball that is going to help you outshine and outscore your competition. Our newest coverstock technology known as XtremeTrax™, features “chemically charged” nano particles which create the highest amount of responsiveness to friction we have ever seen from a nano particle material. But don’t worry, the nano particles will still provide plenty of traction in oil before the “chemical charge” kicks in down lane to provide more change of direction than the original IDOL before it.

Originally introduced in the IDOL™ back in March of 2018, the Ikon Core has become a fan favorite and staple in the arsenals of all the top professionals around the globe. This low RG, high differential symmetrical core revs up in the midlane while providing outstanding continuation down lane which allows it to be used by all styles of players from any angle on the lane.

XtremeTrax™ Coverstock
Derived from countless hours of mixing, formulating, and testing, the Xtreme Traction (XtremeTrax™) material pushes us into boundaries of scientific chemistry. We started with the base materials of our MicroTrax™ coverstock and went down a new path in terms of chemistry by adding different chemicals which in turn created “chemical charges” to the nano-particles, thus making a material that not only digs in on heavy oil, but also provides more responsiveness and reaction down lane than traditional nano materials.

Storm Nova Bowling Ball

The Nova has taken a leap further into space than any ball before. Its revolutionary core has been paired with an innovative combination of coverstock technology to maintain the striking power you’ve come to expect from a Premier Line ball. So, while maintaining the aesthetic that the Premier line is known for, we’ve also brought the performance up another level.

BE SUPER LIKE A NOVA

Weight blocks like the Ignition Core rev up fast and finish strong with a more aggressive movement down lane. Need some extra oomph? Then look no further. The Ignition Core pumps out more than 6” of loaded flare potential! That’s more than enough differential to amp your adrenaline levels. Putting it in R2X means all that power and be harnessed with skilled precision. R2X fits seamlessly between the R2S™ and NRG™ formulas found on some of the most successful Storm balls in recent history. At an ideal 3000-grit finish, the perfect combination of length and strength can be achieved.

900 Global Zen Master Bowling Ball

The S77 Response™ Solid Coverstock was the obvious choice to follow up on the success of the S77 Response™ pearl coverstock. The Solid version of this cover will provide the most overall hook we have ever put in the 800 Series. The Zen Master™ will be a great ball to use on medium-heavy patterns.

The Meditate™ Core is the biggest core we have ever put into a bowling ball!! A bigger core means more hitting power combined with a more consistent reaction. Throughout testing the Meditate™ Core provided that wide “footprint on the lane that all bowlers love to see. The Zen Master™ pushes the limits of core dynamics
