Club Build Info: Brand & Model
Please provide brand & model of your clubs (ex: Titleist T150s 4-PW). This is needed to correctly determine playing lengths and to ensure install specifications are correct.
Playing Length
Standard length varies per model. Please ensure Club Build Info field above is correctly filled out so we can correctly determine final playing length. Fairway Jockey measures the length of clubs based upon the USGA recommended 60° lie angle. Lengths can vary depending on the measuring device used.
SST Puring
SST PURE analyzes the structure of a golf shaft and identifies its most stable bending plane, allowing the builder to assemble the club in an orientation that maximizes consistency. Watch video

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.
