**Why Climbing Rope Loses Strength Over Time—and What That Means for Safety** How much does climbing rope weaken with age? A common question rises in outdoor communities: *What remains of a climbing rope’s strength after four years if it starts at 2,000 pounds and loses 5% each year?* This isn’t just a math puzzle—it’s a critical insight for climbers who value safety, equipment longevity, and informed decision-making. In an era where gear reliability directly impacts risk, understanding how materials degrade over time is essential. The answer reveals both predictable engineering realities and subtle complexities often misunderstood. --- ### **A Hidden Decline in Material Strength**
