Beal Opera 8.5mm

7 items left

Weighing in at only 48 g per meter, the Opera 8.5 is the lightest and thinnest single rope on the market.

Used as single rope, this is not a rope to put in all hands, or in all belaying devices: Its thinness makes it a rope which absolutely demands an expert belayer. In effect, traditional belay devices will offer reduced braking, and some automatic belay devices may not work at all.
