The Beal Opera 8.5mm Unicore Golden Dry is a lightweight single rope weighing in at only 48g per meter. It is also certified as a half and twin rope. The rope is made with technology that combines all of Beal's know-how, resulting in low impact forces, Unicore and UIAA-certified Golden Dry technology in the sheath and core. This ultra-supple, ultralight rope is a favorite of guides and will exceed the expectations of the most demanding rock and alpine 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.
The Opera features Golden Dry treatment, where both the sheath and the core are dry treated. This way the rope has an astonishing water impermeability and incredible durability. In 2012 the UIAA adopted a new requirement for hydrophobic ropes that is now in full force. In this test a rope is subjected to light abrasion and soaked for 15 minutes. The amount of absorbed water must not be greater than 5% of the sample's weight. Beal's Golden Dry ropes easily qualify as "UIAA Water Repellent." A non-treated rope absorbs between 40% and 50% of its weight in water.

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.
