The Beal Opera 8.5mm Unicore is a top-of-the-line single rope weighing in at only 48g per meter. It is also certified as a half and twin rope. This ultra-supple, ultralight rope is a favorite of guides and will exceed the expectations of the most demanding climbers.
The Opera is made with Unicore, an astonishing process where the sheath and core are bonded without affecting the rope’s suppleness. If the sheath is cut or torn, the core and sheath remain bonded together, greatly increasing the safety margin of the rope. Check out the video for more info on this amazing feature.
Dry Cover treatment is applied to the sheath to make the rope more resistant to abrasion and to various attacks such as falls, overheating, humidity, mud and grit, and significantly increases longevity. For both core and sheath treatment, choose the Golden Dry option.

Unicore is an innovative process, bonding rope sheath and core without affecting the rope's suppleness. If the sheath is cut or torn, the core and sheath remain bonded together. With a standard rope, if the sheath is cut by abrasion over an edge, the sheath can slide and gather along the rope length. This can create a potentially dangerous situation. With the Unicore process the sheath remains in place and the rope intact and fully functional.
