The Rocky Mountain® Quiet Crank reduces cocking effort by 90%. Pulls more consistently than conventional methods and improves accuracy by ensuring equal pressure to each crossbow limb. The Quiet-Clutch design has a no-slip brake and can be easily installed or removed in seconds. The ambidextrous design works for both left and right-handed users and the Anti-Torque mounting shaft keeps stable and secure during cranking. The Rocky Mountain Quiet Crank is lightweight & ultra-portable at only 1-lb.
