The R44 Speleo by Singing Rock is a static rope with patented R44 rope-braiding technology developed especially for cave exploring. It is an outstanding rope for its low elongation, high static strength and exceptional resistance to wear. Sheath is made on a 44 carrier machine thus the core/sheath ratio is ideal with reference to the strength of the rope and strength of the rope with knots. The sheath is braided more densely which provides better protection of the core against dirt and dust. Rope runs smoother through belay/rappel devices with lower risk of core prolapse through the sheath when is bent over small diameters.
