Project X IO Iron Shafts were 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
