RUBICON

A drastic departure from our traditional symmetrical core or symmetrical weight block designs in this line, the asymmetrical Rondure™ Core was developed to increase overall ball motion throughout the lane without the aid of an added balance hole. Paired with our most recent formulation of eTrax™ solid coverstock technology, this ball has solidified the position as the “Benchmark Ball” for the Roto Grip line.

Rondure Core

A drastic departure from our traditional symmetrical core or symmetrical weight block designs in the HP3 line, the asymmetrical Rondure Core was developed to increase overall ball motion throughout the lane without the aid of an added balance hole since those are now illegal in sanctioned competition. The starting point of this core was creating a low RG core design with a small intermediate split in order to emulate that symmetrical core with an extra hole type motion a lot of bowlers have grown accustomed to. Dynamically speaking, this core will rev up in the midline while providing more motion down lane than your traditional asymmetrical design. The smaller intermediate differential provides continuation closer to a symmetrical design. Thus, making this part the gap filler between asymmetrical and symmetrical core designs.




eTrax Coverstock

Our purest form of reactive material to date, the Enhanced Traction (eTrax) coverstock sets the standard as the material to which all other materials are compared and tested. Formulated to provide the “true reactive” response on a variety of conditions by easily clearing the front of the lane while aggressively responding to friction down lane, the eTrax material flexes its resilience and durability day in and day out.

Best Ball I've Ever Had
Threw a 223 last night in league. I've never bowled 200 and I'm a 125 average. Got this ball recently and it's just been money for me. Predictable and I've picked up a few strikes that would have been splits with other balls. I play to the middle (stand on 20ish aim for 10) and it doesn't matter the conditions in league, It does what i want every time. Was 23 pins over average last week. 52! over this week. That includes a game where I missed 5 spares. Bowling is cruel at times but this ball is cruel to the pins.

Benchmark.
The layout on my Rubicon is 65 x 5.25 x 30.

The Rubicon provides a cleaner more responsive version of the Idol shape, while still maintaining a controllable benchmark reaction that tournament bowlers need.

Versatility on all conditions is what the Rubicon brings to the table. It is the perfect piece between the UFO/Proton and the Idol/Axiom.
