The Eggbutt Dr Bristol Bit has 2 joints, which means the pressure of the bit is distributed over both the tongue and bars of the mouth. By using tongue pressure to encourage the horse to go on the bit, the flat shaped lozenge centre piece is set at an angle therefore causing a sharper, more pronounced pressure on the tongue, this bit will not encourage a true contact although may be useful if you need that extra bit of help in order to slow down or stop.
An eggbutt bit would be less suitable if your horse is prone to leaning or taking hold of the bit.
