Sterling Rope "Velocity 9.8mm" (60m/Neon Green) I purchased this rope about five years ago, but I'm selling it now because I bought a new one. I've used it as my main rope, so there is some fraying, etc. Please check the photos and consider before purchasing. Climbing is a risky sport, and I am not responsible for any incidents that may occur while using this product. Manufacturer's Description: The "Velocity 9.8mm," a best-selling rope for sport climbing, is a favorite of Sterling Rope, known for being used by sponsored athlete Chris Sharma for his project work. It has few kinks and hardly frays or hardens. It is highly durable and one of the best ropes. Dynamic rope for climbing.
