Project X CATALYST Graphite Iron Shafts available in 40, 50, 60, and 80 gram weight options.
The CATALYST Graphite Iron was designed to replicate steel alloys better than any other graphite.
Project X constructed these irons to out perform other graphite shafts in stability, consistency and distance.
They have a stiff tip area which provides torsional resistance similar to steel shaft models.
