The 10.4 Biathlon Sport Rope by Sterling is the Bi-color version of the Marathon Sport. According to studies done by Sterling, marking the center of your rope with a felt tipped marker or other commercial ink can decrease up to 50% of the rope strength - or the energy absorption capacity of your rope.
Designed for cragging, alpine routes and even big walls, the Biathlon Sport Rope is one of the more versatile ropes in Sterling's line-up. With two distinct patterns on each half of the rope, it is easy to find the middle, helping you in all sorts of climbing situations.
Constructed to be lighter, and incredibly durable with its beefy braiding technology and easy handling, the Biathlon Sport Rope should be a part of any serious climber's arsenal of gear.
