FAQs: How Tight Should a Flank Strap Be?
Q: Does the strap hurt the bull?
A: Properly fitted straps do not cause pain – calves naturally buckle when encouraged. A layer of wool prevents chafing.
Q: How often should I change my strap?
A: Every 200 uses or 2 years (whichever comes earlier). Inspect the wear monthly.
Q: Can I use a rope instead?
A: Absolutely not – rodeo rules strictly require PRCA/PBR-approved leather straps with wool padding for all competitions.
Q: What’s the penalty for wrong tightness?
A: Up to $5,000 fine and 6-month suspension for repeat violations.
The Goldilocks Principle
The perfect flank strap fit is not too loose, not too tight – just enough to allow the animal’s natural bucking motion without disturbing it. Remember:
✔ Measure twice before every ride.
✔ Start loose and gradually adjust.
✔ Prefer woolliners for animal welfare.
✔ Document adjustment for inspection records
