Are shorter oil patterns stopping you in your tracks? Sometime reactive resin is just too much ball. That's where urethane Grenade comes in!
The Retrothane is a traditional urethane coverstock that will help you tame even the most scorching lane conditions. As witnessed on the PBA Tour and in World Championship events, urethane is still effective today.
With a medium RG (2.58) and medium differential (.040), the Photon ™ core utilized in both the newly released Riot and Dark Star, is the perfect foundation for the new Grenade.
Redefine your arsenal with the new Grenade and know that no matter what they throw at you, Roto Grip has you covered.
