Description

The Fusion Photon is Sterling’s first half rope that is also certified to twin. It was manufactured to have a perfect balance of diameter to weight.

Designed to round out the Fusion series as a performance half rope, the Photon is small and light, making rope drag less of a concern over long or windy pitches.

These Fusion Photons are easy to pull when belaying with the Petzl Reverso and CAMP’s Gi-Gi. These lines handle well for such small diameters. The Photons seem a little wiry compared to supple fatter ropes. The wiry feel seems to keep the lines from tying themselves into bites. The colors of our ropes, yellow and purple, were great in contrast and beautifully bright.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
