Private Stock Pro JB1 The Private Stock Pro JB1 is built for hitters who want barrel size without sacrificing bat speed. Designed with a large 2.5” super-dense barrel, this model delivers explosive impact and premium performance on every swing. What makes the JB1 stand out is its perfect taper that quickly transitions from the barrel into a thin neck and thin handle. This design creates an ultra-whippy feel through the zone, allowing hitters to generate elite bat speed with less effort. Finished with a comfortable flared knob, the JB1 gives hitters a smooth, controlled feel in the hands—perfect for staying loose while maintaining full command of the barrel. The result is a bat that combines mass and whip, helping translate swing speed into serious exit velocity. Why hitters choose the JB1: Large 2.5” super-dense barrel for maximum pop Fast taper to a thin handle for extreme whip Built for elite bat speed and higher exit velocity Flared knob for comfort and control Perfect for hitters who want speed without giving up barrel If you're looking to swing fast, hit hard, and drive the ball with authority, the JB1 is built to deliver.
