Teufelberger Tachyon Ash (11.5mm) 24-Strand Climbing Rope is professional arborist static climbing rope. Thanks to its unparalleled feel and its exceptional performance, Tachyon is ideal for use with the latest mechanical systems and functions perfectly in combination with standard hardware designed for use with 11mm ropes. It consists of a polyester cover which significantly improves friction hitch performance without “bagginess”. The inner core construction keeps the diameter consistent, even in the loaded state. The rope diameter of 11.5 mm is ideal for tree care operations as it ensures a better grip, thus reducing hand fatigue. It has low stretch at low loads for less bounce while climbing. As well as high stretch at high loads to minimize impact in the event of a fall. Tachyon is certified to EN 1891A as well as ANSI Z133-2012.
