RetroFit is our patent pending golf shaft adapter which can be used to replace the Callaway OptiFit shaft adapter.  It is designed to provide maximum rigidity in its connection to the head, even at extremely high swing speeds.  The RetroFit is almost 6 grams lighter than the OptiFit which allows for a combination of lower swingweight, longer club lengths, and more discretionary head weight for improved flight control.  The RetroFit's shaft socket bottom is 3/8" closer to the head than the socket of the OptiFit, and it is designed to be used without a ferrule.

The RetroFit is a four position shaft adapter.  We offer an adapter having a socket drilled at a 0 degree skew from axial which is unmarked and provides a club with the head's nominal properties irrespective of the adapter's rotational position.  To adjust the club's loft and lie angles, we offer an adapter having a socket which is drilled at a 1.5 degree skew from axial. thereby allowing for +/- 1.5 degree changes in these angles.  The 1.5 degree RetroFit is marked for RIGHT HAND application.  It can be used in a left hand club but the marks will be 180 degrees off; + is actually -, F is actually D, and vice versa.  We offer the RetroFit in green and black.

We sell these in quantities of two and four, and you can mix-and-match, including color and 0 and 1.5 degree drilling.  Indicate in the notes section your desired assortment.  For larger quantities, contact us for a quote.
