Singing Rock Speleo R44 10.5 is a low stretch rope for suitable work at height and caving rope techniques.

The stated weight of 72 g/m helps compare the total load at your chosen length. On longer approaches or when carrying several ropes, weight per metre matters alongside diameter and intended use.

Static elongation of 3.3 % describes rope behaviour under the specified test load. Low stretch benefits ascent, positioning and hauling by reducing unnecessary movement as weight transfers through the system.

The stated tensile strength of 33.4 kN provides another construction reference. Knots, sewn eyes and rope routing create different loading conditions, so rope breaking strength must be distinguished from the working load of a complete system.

The sheath uses ROUTE 44 technology, designed to combine durability with handling characteristics suited to repeated feeding and taking in of rope.
