FULL DESCRIPTION

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.

Shafts feel smooth but hold up to my swing speed. Nice and stable but with a little kick. I bought the 6.5.

Excellent Addition to the Project X Line of Shafts

Been playing Project X Rifle 6.0's in 716 AP2's with great success. As I'm getting a bit older, wanted to try something lighter and went with the Project X IO 6.0's. Made a great choice. Much easier to swing and the feel is great, in fact better than the Rifles. Still produced a penetrating ball flight, but a bit higher with slighlty more carry. Nice shaft.
