HAMMER Phobia— The newest addition to Hammer’s Upper Mid Performance line is bringing back a symmetric core. Phobia works best on medium-heavy oil patterns, creating a lot of length with a very angular back end motion. Pins and competitors will break into a cold sweat with fear when the Phobia hits the lanes. Be afraid, be VERY afraid.
