McDermott Cues offers several different High Performance Cue Shafts including the McDermott i-Shafts and G-Core cue shafts. Each style of McDermott Cue shaft features unique versions of the core construction to best implement McDermott's triple-layer carbon fiber technology. G-Core shafts carbon fiber starts at the tip of the shaft and extends down 7 inches. This design provides accuracy and power expected of a high performance shaft but with the familiar feel and hit of a conventional all maple shaft. McDermott Cues i-Shafts carbon fiber construction starts again at the ferrule, but extends all the way throughout the shaft making it the most consistent hittting shaft on the market and minimizing the inconsistencies experienced with all conventional maple shafts. The i-Shafts also uses McDermott's Tenon Tip Technology where the ferrule has a tenon fitting inside the carbon fiber core.
