If you're looking for the top deadlift bar with the big whip, it's the Deadlift Barbell. Our Deadlifting bar features a thin flexible 27mm shaft with a sharp, deep, and aggressive knurling made from a durable steel to maximize whip. We were looking for the right balance between bar flex with a bar under load, and the ability to return to straight without a permanent bend for a lifetime of proper usage. All with the intent of allowing the athlete to lift more weight from the floor.
