Head come with the unique Roisub torlon bearings. The tested TS (Torlon system) is designed and studied in detail for use with all types of invert roller/ pulley systems. It is the result of a long process of optimisation, with more than 100 video and audio analyses, slow motion analysis and comparison in various configurations.
TS special pulleys are CNC machined and designed to work with heavy loads. Built with a shell of Delrin® and bearings made of Torlon®, they have minimum tolerances - less than 0.05mm.
The offset has been designed especially for making sure that the different passes of line do not interfere with each other. On the back of the head, inside the spigot, there is an M10 threaded hole, allowing the use of any steel bolt, for optimising the balance and trim of the speargun. The Head is derived from solid delrin, shaped by CNC machines and tested piece by piece to ensure maximum product quality.
