MIZUNO ST-X 220 DRIVER
DRAW BIAS - MID SPIN
THE NEXT GENERATION
A confidence-inspiring, draw-biased driver with heel focussed weight location. The ST-X will appeal to players seeking a higher, right to left ball flight. With higher spin rates than its ST-Z counterpart, the ST-X, will suit moderate swing speeds, needing help producing a more extended ball flight. A new 20-gram heel biased back weight creates a deeper centre of gravity for more efficient, longer drives- more often. Also available as a J-Spec option with ultra -lightweight HeLIUM NanoCore shaft for seniors and slower swing speeds.
“FOR A LOT OF GOLFERS, THE MODERN LOW SPINNING DRIVER DESIGN PREFERRED BY TOUR PLAYERS IS A SERIOUS DISTANCE KILLER. THE ST-X’S EXTRA SPIN, SLIGHT DRAW BIAS AND A HIGHER FLIGHT WILL ADD DRIVING DISTANCE FOR A SURPRISING NUMBER OF PLAYERS.”
CHRIS VOSHALL, DIRECTOR OF PRODUCT
More Performance. More Often.
The ST-X delivers your optimum 'more often' through exceptional stability from off-centre strikes. An expansion of the carbon sole area by 40% and thinning out the Titanium portion. Alongside a near doubling of the stabilizing heel/back weight.
Highly Resilient Forged SAT2041 Beta Ti face
Maintains its characteristics and resists micro-fractures longer than the commonly used 6-4 Ti. Elevated though a mutli-thickness CORTECH design for increased ball speeds.
FOCUS ON LAUNCH STABILITY
Ball Speed
CORTECH, SAT2041 Beta Titanium, WAVE, and CT ribs contribute to higher speed and larger CORAREA
Launch Angle
At impact depends on dynamic loft, attack angle, and impact position relative to the Sweet Spot
Back Spin
At impact depends on attack angle, dynamic loft, and impact position relative to Sweet Spot
High Draw Flight bias
Mizuno’s X-Axis design - weight is focussed deep in the heel, encouraging a higher draw bias flight.
FEATURES
Slightly Rounded Profile
A rounded 460cc volume for higher launch and mid spin performance.
Engineered for ‘solid’ feel
Mizuno's Harmonic Impact Research identifies and isolates vibration patterns that elite players associate with a preferred 'solid' feel. Knowledge of exact, preferred vibrations allows Mizuno to build sound into the design.
Optimized Wave Sole
Delivers an additional contribution to ball speeds, particularly from low on the club face.
Quick Switch Adjustability
With 4 degrees of loft adjustability to fine-tune launch and trajectory.
