5/16 X 18 Black Collar McDermott IPRO Pool Cue Shaft 12.5mm

McDermott iPro 5/16 x 18 Black Collar pool cue shaft.  McDermott iPro is a 12.5mm high-performance cue shaft. Joint Diameter is .840″. The iPRO  shaft has an  Octadic Laminated Shaft Construction that features eight spliced pieces of premium maple that are bonded together to form our most radial consistent shaft yet.  The i-Pro’s Triple-Layer Carbon Fiber Core extends the full length of the shaft (from ferrule to joint), stabilizing the entire shaft for absolute control and predictability. This technology increases radial consistency, reduces vibration, and virtually eliminates the inconsistencies found in a traditional maple shaft.
