The Most Tunable Asymmetric Solid in the Game

About the Transformer

The Roto Grip Transformer is built around one idea: tunability. It pairs the drill-tunable Morph-Wing asymmetric core with the nano-free V-R1 Solid Reactive coverstock to give serious bowlers and pro shops the most adjustable ball motion in the lineup. The Transformer does not just react to the lane, it can be drilled to transform into the exact shape your game needs.

That adaptability comes from the Morph-Wing core. Unlike a traditional asymmetric, displacing mass in the wing section during drilling fundamentally changes the core numbers, unlocking a completely new flare pattern and ball motion. Wrapped in the balanced, dependable traction of the V-R1 Solid cover at a 4000-grit finish, the Transformer reads medium to medium-heavy oil with strong, controllable hook. Stop adapting to the lanes and make the lanes adapt to you.

Understanding the Roto Grip Morph-Wing Core and Roto Grip V-R1 Solid Reactive

Roto Grip built the Transformer to be the most tunable asymmetric in the lineup. Specifically, the Morph-Wing core is engineered to change drastically when drilled: removing mass from the wing alters the core numbers, so your pro shop can reshape the flare and motion to fill almost any slot in your bag. The nano-free V-R1 Solid Reactive cover, finished at 4000 grit, delivers the most balanced traction-to-reaction ratio of Roto Grip's nano-free materials, for strong but controllable hook through medium-heavy oil. The full per-weight specifications are listed below.

A Drill-Tunable Asymmetric Core That Transforms When Drilled

At the heart of the Transformer is the asymmetric Morph-Wing core. At 15 lb it measures RG 2.51, a strong .051 differential, and a .015 intermediate differential (mass bias), numbers that produce strong, defined asymmetric motion. What sets it apart is the wing geometry: unlike a traditional asymmetric, displacing mass in the wing section during drilling fundamentally changes the core numbers, unlocking a completely new flare pattern and ball motion.

That is the whole point of the Transformer. The same core can be laid out for an earlier, smoother roll or a later, more angular shape depending on how the wings are drilled, so one ball can be tuned to fill more than one slot in your arsenal. It is one of the most adaptable asymmetric cores Roto Grip has built, and it rewards working with a good pro shop to dial in the exact reaction you want.

A Nano-Free Solid With the Most Balanced Traction-to-Reaction Ratio

The Transformer wraps that tunable core in the V-R1 Solid Reactive coverstock, finished at 4000 grit. The V-R1 (Versatile Response) solid is a nano-free formulation that Roto Grip built to deliver the most balanced and dependable traction-to-reaction ratio of any of its nano-free materials. It grabs the mid-lane for an early, controllable read, then responds smoothly to friction down-lane rather than jumping.
