Fast Revs and Strong Continuation
About the UNIT
The Roto Grip UNIT introduces the brand-new symmetric Actuator Core, including a drillable Gyra-ORB near the top of the weight block, inside the proven U-R1 Solid Reactive cover. It arrives December 4, 2026 in Cerulean / Black.
Roto Grip built the UNIT for medium to medium-heavy conditions. The company says it revs up fast, provides strong continuation and lets bowlers open their angles without losing drive through the pins. The U-R1 Solid cover is finished at 4000-grit Abralon.
Understanding the Roto Grip Actuator Core and Roto Grip U-R1 Solid Reactive
The UNIT is a symmetric solid reactive ball with a 2.48 RG and .045 differential at 15 lb. Its U-R1 Solid Reactive cover is finished at 4000-grit Abralon, and Roto Grip rates its flare Medium-High for medium to medium-heavy conditions. The 13 and 12 lb weights use a dedicated core design. The full per-weight numbers are listed below.
A Brand-New Symmetric Core With a Drillable Gyra-ORB
The UNIT introduces the symmetric Actuator Core. At 15 lb it measures a 2.48 RG and .045 differential. Roto Grip says the design revs up fast and stays in motion through the pin deck.
A drillable Gyra-ORB sits near the top of the weight block. Roto Grip says this internal element keeps the overall RG down while maximizing energy retention as the ball moves down the lane. The 13 and 12 lb UNIT uses a dedicated core design.
A Proven Solid Cover at 4000-Grit Abralon
The U-R1 Solid Reactive cover surrounds the new Actuator Core and ships at 4000-grit Abralon. Roto Grip describes U-R1 as a proven solid formulation.
Roto Grip says the cover glides smoothly through the front without grabbing prematurely, stores energy and delivers an ULTRA-Response to friction at the breakpoint.

Good to Know Before You Buy
BowlersMart Tips: Where the UNIT Fits in a Roto Grip Arsenal
Where It Fits in Your Arsenal
The UNIT is a symmetric HP3 solid for medium to medium-heavy conditions. The Wicked Gremlin adds an asymmetric HP3 option for medium-heavy oil, and the Perfect Gem is the HP4 asymmetric option for heavy and medium-heavy oil.
Surface Adjustments
Keep the 4000-grit Abralon box finish unless your pro shop recommends a change. Have surface work done at your pro shop for an even, consistent finish.
Coverstock Care
Reactive covers absorb oil over time. Wipe the ball down after every set and deep clean it periodically so the U-R1 Solid Reactive cover stays clean.
