autoFlex appeared in two places in Michelle Wie West’s bag at the 2021 U.S. Women’s Open. The equipment list published by GolfWRX on June 4 recorded SF505 X shafts in both her driver and her 3-wood.
One shaft model, two club combinations
The listed driver head was a Callaway Epic Speed Triple Diamond DS, while the 3-wood used an Epic Speed Triple Diamond head. Both entries named autoFlex SF505 X.
A driver and a fairway wood serve different purposes and use different head and length combinations. This makes the record more specific than a single brand appearance: it documents autoFlex as part of two separate club builds at that event.
A moment preserved in the equipment archive
A tour equipment list is a snapshot of a player’s choices at a particular time. It also reminds us that a shaft is one part of a complete club. The same model can be assembled differently for different golfers, and a tour setup should not be treated as a universal fitting prescription.
