iSeries Wood Shafts

Engineered with a new proprietary carbon weave in the butt section, this design enhances overall shaft stability while delivering a more connected, responsive feel throughout the swing. A shorter bendable beam length paired with an active tip section promotes increased energy transfer and added clubhead speed, helping golfers generate more efficient launch and performance.

Dedicated fairway wood and hybrid models are “DyMatched” to the driver profiles, creating a seamless progression in feel and performance across the top end of the bag. Updated graphics align with the iSeries iron shaft lineup, offering a clean, modern aesthetic that completes a unified equipment setup.

Features

Spin

Spin is the amount of backspin that the ball has. The designs of certain golf shafts can promote more or less spin so keep this in mind when looking for a shaft to maximize your game.

Tempo

Tempo is not how fast you swing it, it is how you swing it fast. Tempo will affect how you load and unload the shaft and is a big factor in which shaft will best suit you. A player with a quicker backswing and more aggressive transition will have a faster tempo, while a player with a slower backswing and smoother transition will have a more deliberate tempo.

Trajectory

Trajectory is the flight of the ball and the peak height that the ball reaches. A player who struggles with getting the ball in the air should look towards a higher trajectory shaft, while a player who struggles hitting the ball too high should look for a lower trajectory shaft.
