News — 2023 Avenge Pro

The prevalence of the term “MOI”, an abbreviation for “Moment of Inertia”, has become much more prevalent in today’s world of baseball and golf specifically. But what exactly does this term mean, and how does it relate to your baseball bat?

MOI is an engineering metric used to quantify the rotational inertia of an object – or the object’s tendency to resist angular rotation.  In this sense, it is similar to the concept of torque, and is measured in respect to a single “pivot” point.  In the case of bats, the pivot point is the hitter’s hands, and thus, all MOI measurements are calculated from a single point (6.0” from the tip of the knob) that approximates the central axis of an average hitter’s hands during the swing.

The Avenge Pro Hybrid features the BBCOR debut of Axe Bat’s newest barrel technology: Precision Variable Blastwall.

Utilizing proprietary manufacturing technologies, our aluminum barrels are machined via CNC lathe to meet tolerances not previously possible. All 14-16” of barrel (dependent on bat length) is machined to tolerances as tight as 0.05mm – all to meet the peak performance players are accustomed to when stepping into the box with the industry’s newest hybrid in their hands.

Every size of each Avenge Pro Hybrid model is modeled via computer aided design (CAD) software to not only create product drawings and specifications for manufacturing, but more importantly, to simulate both weight and moment of inertia (“MOI” or “swing weight”) calculations before a bat barrel is ever created.  This allows our engineers to iterate countless times via CAD to ensure products are meeting specifications prior to manufacturing.
