VICTUS JC24 BIRCH PRO RESERVEJC24 Birch Pro Reserve The JC24 is arguably the most well balanced and most durable bat we produce, constructed similarly to the C271, but thicker in the areas essential to keeping a wood bat in one piece. The slightly flared knob provides a comfortable resting spot for your bottom hand. If you're making the transition from metal bats to wood bats, the JC24 is for you even better for contact hitters who consistently drive the ball deep in the gaps.
