Have you ever wondered what the number designation on your Project X shaft means? You know, the 5.0, 6.0, 6.5 and so on printed on the shaft. These numbers correspond with flexes from 'regular' to 'extra stiff plus'. While the flex is sometimes written on the shaft, many times it isn't, leaving only the number to inform you of the flex. The only problem? The flex that corresponds with each number often changes based on the shaft model. And the power of Google can fail you as you search for a cohesive list of all of the flex code meanings. Even the Project X website lacks any kind of compiled guide, and only some of the individual shaft product pages reveal which numbers go with which flex.
Not to worry. We've created an extensive list of Project X shafts and their flex codes. We'll update the list as more shafts are released in the future.

It's important to note that there has been much discussion around the designation of flex for Project X versus other shafts. A 'stiff' flex from one shaft producer will not always equal a 'stiff' flex from another. While these codes are accurate based on the flex that Project X indicates, your mileage may vary on how well the feel of the shaft matches the maker's designation.
