The Pechauer Black Ice Break Cue Shaft – Viking QR 13.00mm combines our patented Infused Chemical Engineering (ICE) Technology with a 5/16 x 18 joint to create a powerful break shaft. By infusing chemicals into the wood cells, the density and smoothness are increased, resulting in less friction and higher velocity. This multi-step process permanently penetrates the entire shaft, providing a weight-forward balance for effortless and powerful breaks. With an average weight of 6.4 oz, this break shaft is designed to deliver maximum power with minimal effort, making it the perfect addition to any cue.
