ALDILA MOI 65 I-Mix Shaft
This new shaft is the answer to the oversize high moment of inertia (MOI) drivers. To help counteract the unwanted loading effects caused by high MOI heads, Aldila increased the area MOI (aMOI) of the shaft. Increasing the aMOI increases the stiffness. The increased stiffness helps negate the effects of the increased loading from the modern clubheads.
Callaway I-MIX Drivers are designed to allow you to mix and match your driver's head and shaft for your optimal performance.
