Used Cobra KING F9 SPEEDBACK Mens Iron Set LH 5I-PW

Cobra KING F9 Speedback Men's Iron Set (Left Hand, 5I-PW)

The Cobra KING F9 Speedback Iron Set is a game-improvement powerhouse blending explosive distance, high launch, and forgiveness through innovative weighting and face technology, making it Cobra's longest iron set at release. This left-handed 6-piece set (5-iron through Pitching Wedge) features a progressive cavity-back design with a sleek chrome finish, hollow-body construction in the longer irons for added speed, and a confidence-inspiring look at address. Tailored for mid-to-high handicap golfers (10+), it delivers consistent yardages from 170-140 yards per club, promoting straighter shots and easier turf interaction—ideal for upgrading from older sets.

Key Features:

• Speedback Technology: A low, rear tungsten weight (up to 33g) and perimeter steel belt lower and deepen the CG for higher launch, increased MOI (up to 10% more than predecessors), and enhanced stability on mishits, while maintaining a traditional sole width for clean strikes.
• Forged E9 PWR-Shell Face: Variable-thickness (1.8mm thin at center) forged 17-4 stainless steel face with an internal 1.2mm Speed Channel expands the sweet zone by 95%, boosting ball speeds (up to 2-3 mph faster) and distance without strong lofts; CNC-milled for precise spin control.
• Progressive Design: Hollow-body in 5-6 irons for max distance; cavity-back in 7-PW for control. Progressive hosels (shorter in longs for low CG, longer in shorts for higher CG) optimize flight. Grooves vary by club: V-grooves (4-7) reduce spin for distance; U-grooves (8-PW) tighten for accuracy; denser spacing in PW for greenside bite.
• 3-Piece Multi-Material Cavity Badge: Dampens vibrations for a soft, solid feel and crisp sound, improving feedback on pure and off-center strikes.
• Progressive Shaft Weighting: Lighter shafts in longer irons for speed/high launch; heavier in shorts for control (steel: KBS Tour 80 in 5-6, Tour 90 in 7-9, Wedge in PW; graphite options available).
• Arccos-Enabled Grips: Lamkin Crossline with embedded sensors track shots via app (subscription required) for data-driven improvement.
