Hammer TNBA The Chalk 15 Only Bowling Balls
TNBA The Chalk 15 Only Specs
Put the strikes up on the scoreboard with The Chalk!
The Chalk is the latest ball designed to continue raising awareness of one of the most historic bowling organizations in America, the TNBA!
The Chalk combines our very popular Raw Hammer Assault core with the GTR Pearl, made famous by the Taboo line. This creates a medium oil ball with an incredibly strong, controllable move on the backend! A portion of the proceeds from every Chalk ball sold will go to support the TNBA.
