What does the ported design do in this bit?

The port (the raised curve in the centre of the mouthpiece) creates space for the tongue, reducing pressure on it. This makes the bit more comfortable for horses that are sensitive to tongue pressure or have a low palate.

What is the Acavallo Sensitive Bit made from?

The mouthpiece uses Acavallo's revolutionary flexible material that's warm to the touch and gentler than metal. The D-rings are made from durable alloy. The combination provides a soft, consistent contact.

Is the D-Ring design better than a loose ring for sensitive horses?

D-rings provide a more stable, fixed contact point which many sensitive horses prefer — there's no pinching risk at the corners of the mouth and less movement in the mouthpiece. It's an excellent choice for horses that fuss with loose ring bits.

What sizes does the Mullen Ported D-Ring come in?

Available in standard bit widths. Measure your horse's mouth width accurately to ensure the correct fit — a bit that's too narrow will pinch, while one that's too wide will slide and create uneven pressure.

Is this bit legal for dressage competitions?

Mullen mouth and ported bits are permitted in many dressage competitions, but specific material rules vary by governing body. Always check your discipline's current rulebook before competing with a non-metal bit.

The revolutionary Acavallo Mullen ported D-ring bit is made from a cutting-edge anti-allergic plastic material, replacing the traditional heavy, cold metal alloy.
Featuring integrated, flexible steel reinforcement, this bit offers smooth, highly secure control for your horse.
The one-piece design of the mouthpiece and rings prevents one-sided compression or pinching of the tongue or jaws, as well as reducing unpleasant irritation on the palate. This high comfort improves the connection between horse and rider, allowing for smooth movements.
Featuring a port that reduces pressure on the tongue and distributes it across the palate.

Hand washable with water and mild soap
Do not use aggressive cleaning agents
Leave to dry naturally or dry with a soft cloth
