The Elliptical is a 45 mm lozenge, it is stronger than the Control Plate due to it having a smaller surface area. Consequently, a horse using his tongue as a means of pushing against the bit and therefore taking control, will draw back and tuck his chin in, coming back to a better point of control.
The mouth piece is made from blue sweet iron, because it:
helps bit acceptance
is warm and sweet
Please note the blue will fade with use.
The Polo Pelham is supplied with stubby curb hooks and a flat link polo curb chain.
