Exogrid with Ph.D Technology:
Tapered slots are precision cut from the 5150 alloy frame, making
room for lighter and stronger 12K carbon inserts
Proprietary bi/fusion process joins the stiff exogrid carbon
sleeve and Ph.D vibration damping layers to the 5150 alloy frame
The resulting structure offers the ultimate combination of
stiffness and feel
Exogrid with Ph.D Features:
Some players perform better with a stiff handle bat. Until now
those players had to compromise a sweet feeling bat for peak
performance because as a bat gets stiffer, its vibrational response
increases. By incorporating Ph. D technology (Passive Hybrid Damping)
into stiff handle bat designs, the need for compromise is over. Ph. D
is the ultimate in vibration reduction technology, it will
revolutionize the feel of stiff handle bats because it filters out
harsh vibration more effectively than any previous technologies.
