Roto Grip RST X-1 Bowling Ball

Roto Grip RST X-1 Bowling Ball

A new spin on an old classic - The RST X-1 from Roto Grip is here. Roto Grip took inspiration from their 1950's roots to produce a ball with today's technology that can stand the test of time. The newly designed RST asymmetric core will produce a clean, consistent reaction and smooth continuation down lane.

Wrapped around the outside, the MicroTrax Hybrid reactive coverstock finished at 3000-grit Abralon will handle medium-heavy lane conditions with grace. It's versatile responsiveness will make this a great staple piece for any different style bowlers.
