Acer Velocity Black Ladies/Senior .370″ Graphite Irons
The Acer Velocity Black graphite shaft for irons uses a 0.370″ tip diameter with a 5.5″ parallel tip section and a 0.580″ butt diameter. This combined ladies and senior flex design aims to provide easier loading and a higher launch. With a shaft weight around 66 grams, it suits players seeking a lighter feel without sacrificing stability in the swing. The high launch angle can help players achieve more carry and improved greenside approaches.
Key features include a convenient combination flex setup for hybrids, irons, and wedges, and a ball flight optimized for players requiring smoother tempo. This shaft model prioritizes a balanced blend of control and distance, particularly for players who prefer a lighter, more forgiving option in the hybrid-to-iron range.
SK Fiber Tour 90 HL Steel Iron Shafts
The SK Fiber Tour 90 HL steel shafts come in a 0.370″ tip diameter with a 9.875″ parallel tip section, designed for a mid-to-high ball flight. They measure a butt diameter of 0.600″ and weigh about 105 grams uncut, with approximately 90 grams after cutting for a typical 7-iron. The combination of steel construction and mid-high trajectory supports consistent feel and distance across the set, making them a solid choice for players seeking stability and predictable iron shots.
These shafts are built as a robust option for players who want steady energy transfer through impact and a dependable mid-high flight profile. The stepped steel design contributes to a steady weight distribution, improving feels during the swing and on contact with the ball.
PROJECTX Old Town Cypher Iron Shaft
The PROJECTX Old Town Cypher iron shaft emphasizes an ultra-lightweight design intended to increase swing speed and deliver more distance. It features a high-launch profile to optimize trajectories and carry, while maintaining a smooth energy transfer for precise iron play. The design supports controlled performance, making it appropriate for players seeking faster tempos without sacrificing feel or consistency on mid-to-long irons.
Key attributes include a focus on effortless power, a high-launch trajectory for longer carry, and an emphasis on consistent energy transfer to the clubface. The shaft is described as precise and responsive, aligning with players who want predictable results across different iron distances.
Acer Velocity Black Men .370″ Graphite Irons
This Acer Velocity Black graphite shaft for irons is a regular to stiff combination flex option for men, with a 0.370″ tip diameter and a 5.5” parallel tip section plus a 0.590” butt diameter. Weighing roughly 69 grams, this shaft offers a balance of light feel and stability for a controlled iron swing. The shaft is designed for a high-launch ball flight, making it suitable for players seeking extra carry without sacrificing control on approach shots.
The 40-inch length and 4-degree torque specification contribute to a steady action through the swing, helping to dampen left-right dispersion while promoting consistent contact across the irons in a standard set configuration.
SK Fiber Hypersonic SL50 Ultra Lightweight .370″ Graphite Irons
The SK Fiber Hypersonic SL50 is an ultralight graphite shaft designed for faster swing speeds and reduced effort through impact. Featuring a 0.370″ tip diameter with a 5.9″ parallel tip section and a 0.600″ butt diameter, this shaft weighs about 58 grams and has a torque of 4.4 degrees. The light construction and balanced torque are intended to yield smooth acceleration and responsive feel, particularly for players seeking to maximize distance while preserving control in their iron play.
Further Considerations For Iron Shaft Selection
When selecting iron shaft options, consider shaft material (graphite vs steel), tip diameter compatibility (0.370″ is a common size for many irons), weight range, and flex profile. Graphite shafts generally provide lighter weight and higher launch, appealing to seniors, women, or players seeking faster swing speeds with a forgiving feel. Steel shafts tend to deliver lower flight and tighter dispersion, preferred by players seeking precision and stiff feedback at contact. Flex choices (regular, stiff, plus) should align with tempo, swing speed, and your current iron set composition.
Buying Guide: Key Purchase Considerations
- Material: Graphite for lighter feel and higher launch; Steel for durability and lower flight.
- Tip and Butt Diameters: Ensure compatibility with your irons; 0.370″ is common for many models.
- Weight and Torque: Lighter shafts with higher torque support faster swing speeds; heavier shafts with low torque offer stability.
- Flex Profile: Match flex to swing tempo, transition, and distance needs across your iron set.
- Launch and Trajectory: High-launch designs aid carry; mid-to-low launches suit penetrating ball flights.
- Compatibility: Verify length, kick point, and overall club fit with your current irons and grips.
These considerations help compare options across graphite and steel shafts, aligning performance with individual swing characteristics. By evaluating the listed products against your tempo, strength, and goals, you can approach this upgrade with a clear plan and realistic expectations.
