The new Project X IO was born from the concept that not all golfers need the same thing from a shaft. While the stronger players require launch and spin reduction to control their ball, many golfers need more launch and spin to help maximize their distances. Project X IO takes the DNA of the popular PXi shaft and evolves it by having each shaft flex designed with a specific weight and trajectory progression in mind. As Project X IO increases in flex, it gets 5g heavier and is geometrically modified to launch lower–providing an individually optimized shaft for each flex. Project X IO is ideal for players who love the stability of Project X but need an easier to load shaft profile and are looking for a lighter weight option. IO also features a unique brushed chrome finish that reduces glare and gives Project X IO a distinct look.
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 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.
