Tecnifibre Triax - String Reel Gauge:16 This is the technique thatTriax by Tecnifibre is a comfortable string that adds easier access to spin with its unique construction that includes stiffer polyester fibers woven into a nylon based weave. Multifilament strings generally emphasize comfort for soft and arm friendly feel and due to the elastication they will provide plenty of access to power. Triax brings you a higher level of arm protection, thanks to the use of Polyurethane (HD) whose flexibility is set to 100%.
