Nike Golf Dymo STR8 Fit Driver All Nike SQ Dymo Drivers are engineered from the ground up with the express purpose of optimizing the launch and spin by loft. Performance is maximized in every loft by varying multiple specifications from lie angle, to MOI and CG placement, to overall head size and face depth. Features: STR8-FIT Shaft Adapter and Hosel System: Allows for eight possible head positions resulting in eight different shot shapes - all in a single driver. Round Geometry: A new folded round geometry repositions square mass into a round format for workable distance and control. UST Proforce AXIV Core Shafts: Engineered into the interior of the shaft, AXIV Core material increases the shaft s "hoop" strength, and counter-balance effect. Providing a stable environment at impact and making it easier to swing the club head faster. New 3600 Grip Design: Designed to work and feel the same in any direction.
