The beaded curb is designed to school a horse that has lost respect for the flat chain or twisted chain curbs. After numerous competitions runs a horse may need to be reminded to respect the rider. You can change up the curb but leave the bit the same. When the beaded curb is engaged, it will create more push forward of the poll. When this happens, the topline extends allowing the abdominal muscles to contract more efficiently. When this takes place, the bottom of the pelvis comes forward helping to place hind legs up under the body, and the sternum pushes up on the wither making the front feet lighter. This curb should be used in schooling at high-speed competition rate, then removed when respect is renewed. This preserves the curb area for the future. This curb is available in one length, which fits most competition schooling bits.
