Motiv Recon Bowling Ball Core
The Reverb™ outer core of the RX1 is a low-density polyester resin with pin piercing hardness and strength. Rather than absorb impact energy, this outer core reverberates energy as it explodes through the pins.
The Recon™ core drives the RX1 into the heat of battle. It provides a higher RG to control revs and a moderate differential to smooth out reaction down the lane. The 15# RX1 has an RG of 2.59 and a .025 diff.
