RCKLESS COMPOSITE -5 TECHNOLOGY
Every inch of the RCKLESS Composite -5 is engineered to move energy from your hands into the ball. Here's what's working underneath the grip.
FLEX COMPOSITE BARREL
Fiber-layered energy exchange for maximum barrel flex and extreme responsiveness, backed by an explosive sound on contact.
OLS CONNECTION
A one-of-a-kind design that creates the stiffest connection available while dismissing virtually all vibration on contact, for the strongest, smoothest swing yet.
PFX COMPOSITE HANDLE
The Player-Optimized Flex Composite handle is engineered specifically by weight drop, adjusting flex characteristics to enhance swing speed, power, and feel.
RING-FREE BARREL CONSTRUCTION
No restrictor rings means more barrel flex and increased performance with no "dead" spots anywhere on the barrel.
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, locking in grip security from the first swing to the last.
