2½ Ring Petros Colin Miles

( 0 )

Width
Thickness

A Ring cheekpiece introduces poll pressure as well creating leverage on the mouthpiece, the 2½ Ring version is the softest version of ring bit as the ½ ring softens the leverage on the mouthpiece and poll.

The Colin Miles is a great schooling bit with a 55mm centre piece creating greater tongue pressure and reducing bar pressure. The rings give the horse something to play with and help keep the horses attention on the bit.

This particular joint exerts more pressure than the Control Plate or Elliptical.

The Petros mouthpieces rotate preventing the horse taking hold of the bit. Often good for a horse that leans or tries to take hold of the bit.

Notes:
1 The measured width of a horse's mouth (from corner to corner with no wrinkles) rounded up to the nearest 5mm. These are typical values for the breed. MMS = Measured Mouth Size. Click here for more information on measuring your horse's mouth
2 Factors to be added to the measured width of a horse's mouth to ensure the bit width is calculated correctly. This varies depending on the mouthpiece and cheekpiece of the bit. For this bit add 5 mm for a loose ring cheek piece, to allow for space between the ring and the horse's lip, eliminating a possible pressure point and pinching. Add 10 mm for a single or double break bit. This is to allow the bit to follow the contour of the horse's mouth.
3 The width of the bit for a optimal fit, taking into account its components and the width of the horse's mouth. If calculating a bit width based upon a previously purchased Bomber bit, please make sure all relevant adjustments for differences in cheek and mouth pieces are adhered too.
4 Measurements in inches are approximate.

I took this bit to UK and let my sister use it on her horse. He had been using a vulcanite Pelham. He is going well in the Colin miles bit and Julie I'd not finding him too strong. He is really starting to go in a more relaxed frame
