The Project X IO was released in 2020 with the Project X LS and shares the new True Temper look of a matte brushed chrome finish. It is in the same weight range as the discontinued Project X PXi but has a different EI profile. It is lighter and has a low tip to butt stiffness ratio to promote a higher launch.
