7" cheeks, 5" mouth, 1 3/8" port. Great option to aid the rider in aligning the horse's body. Loose mouthpiece and independent shanks makes it an excellent transition bit from the ring snaffle to the leverage bit; excellent choice for pasture or trail riding. Quick link curb offers firm yet non-intimidating control. Sweet iron will rust to taste sweet and increase salivation for a supple mouth.
