SX10 extension Pre-preg carbon tube, with increased wall thickness to 3.8 mm for the ultimate durability against bending and breaking. Fitted with a stainless steel cleat/pulley offering the best weight to stiffness ratio and creating very light weight as well as being very durable and load resistant. Designed for the ultimate performance and maximum longevity. Features- Quick-lock release. - Stainless pulley system for less friction and greater durability.- Stainless clamshell adjustment system.- Dynema rope for reduced friction and increased longevity. STAINLESS STEEL PULLEY SYSTEM Heavy duty load carrying stainless caste structure, which transfers the load directly from the pulleys onto the extension tube without relying on any plastic components. Stainless pulleys for less friction and greater durability.Comes standard with Dynema rope for reduced friction and increased longevity. STAINLESS ADJUSTMENT SYSTEMQuick and easy to adjust, user friendly operation in all temperatures and fail safe construction. UNIVERSAL PIN RELEASE SYSTEMSecure connection between board and rig and quick release with a press of a bottom. PRE-PREG CARBON SX10 stands for 100% carbon content on the tube. It is designed from a top grade and high tensile strength pre-preg carbon. This technology ensures optimum control of resin content and resin distribution throughout the laminate. The carbon layup features a 45 degree carbon weave optimal stiffness to weight ratio.
