Boca Elite FlexRoller™ Curb Strap PATENTED TURNAROUND TIME IS 10-14 BUSINESS DAYS. Designed for horses that need less pressure than a standard chain curb but more than a plain leather curb. The silicone beads squish down when making contact with your horse’s jaw, providing softness and give while still maintaining effective control. Plus, the FlexRoller™ design allows the curb to “flex” to your horse’s jaw when the bit is engaged, creating a more comfortable and responsive feel. The multiple pressure points from the beads offer more grip without causing stiffness or overreaction. ✅ Perfect for sensitive horses✅ Encourages light, effective communication✅ Helps prevent stiffness & brace✅ Flexes to your horse’s jaw for comfort & responsiveness✅ Durable, high-quality design Upgrade your setup with the Boca Elite FlexRoller™—gentle, effective, and built to last! ⚡️🐴 Measurements: Small: Suitable for bits with a shank length of 4.5 inches or less and a purchase under 1.2 inches.
