Brunswick Nirvana Bowling Ball

The new ECS (Enhanced Composite Segmentation) coverstock is Brunswick’s hottest innovation in performance enhancing technology. ECS expands the soft segments of the polymer chain producing improved friction and wider sweet spot resulting in fewer adjustments. ECS technology generates a faster refresh rate and a longer performance life for the coverstock. 

The new Nirvana Ultra Low RG core features a single density rounded elliptical inner core. The core is dynamically designed to optimize ball motion with multiple drilling options for increased pin action and higher scores. 

The new Nirvana with its 1500 grit Siaair Micro Pad finish, provides easy length through heads, exceptional mid lane traction and impressive backend continuation on medium oily to oily lane conditions. 

The Nirvana can be drilled using the standard drilling techniques developed for asymmetric core bowling balls. 

At Brunswick, the unique core shape of each individual ball is used for weights from 14 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range. At 12 and 13 pounds, Brunswick uses a generic core shape with a RG-differential that is close enough to the 14 to 16 pound shape so the same drilling instructions can be used.
