RCKLESS GEN 2 ALLOY -8 TECHNOLOGY
Every inch of the Rckless Gen 2 Alloy -8 is engineered for a clean, traditional swing with none of the dead-spot feel of a standard one-piece bat. Here's what's working underneath the grip.
RING-FREE BARREL CONSTRUCTION
No restrictor rings means more barrel flex and increased performance with no "dead" spots anywhere on the barrel.
AV3 VIBRATION DAMPENER
This 3rd-generation Anti-Vibration Technology sits in the handle of the bat, absorbing vibration and sting for unmatched feel and comfort.
AZR ALLOY BARREL
A responsive, durable alloy that provides better feel, more forgiveness, and more performance across the barrel.
MULTI-VARIABLE WALL DESIGN
Wall thickness varies across the barrel profile to create an expanded sweet spot and thinner barrel walls that are more forgiving after off-center contact.
TFX ENDCAP
An engineered soft-compliance cap that allows more flex on distal impacts, expanding the sweet spot and softening mishits for more forgiving contact.
CUSTOM-MOLDED HAND TAPER
Ergonomically designed for each weight drop for a better fit, more bat control, and a better overall feel between athlete and bat. Easily removable to fit each athlete's preference.
OPTIMIZED KNOB DESIGN
Knob shape is tuned for each weight drop for better hand feel and comfort.
PLAYER BENEFITS

Vibration control built into the handle — the AV3 Vibration Dampener strips out sting and feedback for unmatched feel on every swing.
