String Stretch

String stretch describes how much a bowstring elongates under tension. The amount of stretch varies depending on the material and directly affects the bow’s shooting behavior.

Why it matters:

• More stretch → slightly lower arrow speed
• Less stretch → more direct energy transfer
• Stretch affects brace height and nock point
• Excessive stretch can alter tuning

Material differences:

• Dacron → higher stretch, gentle on traditional bows
• Modern high-performance fibers (e.g., Dyneema) → very low stretch, faster and more direct

In short:
The stretch of a string determines how directly energy is transferred—it influences speed, feel, and tuning of your bow. 🔥🏹
