The Jacoby Ultra Pro Shaft 12.75mm diameter is engineered for players seeking greater precision, consistency, and reduced cue ball squirt. By minimizing front-end mass and increasing shaft flex, it allows the cue ball to stay truer to its intended path when applying English. A feather-light Hydex 202 ferrule and vibration-dampening core work together to reduce deflection, unwanted vibration, and front-end weight for a more accurate, stable hit. Built from 140 precisely machined veneers stacked on edge at 90 degrees to the centerline, the shaft delivers exceptional balance, symmetry, and radial consistency. Its 18–20 inch taper and laminated construction provide reliable feel, shot-to-shot consistency, and dependable performance from one shaft to the next.
