RNF’s provide slightly less stopping power than a pelham and have taller cheeks creating a slight gag effect. They also have 3 adjustable rein configurations that change your amount of lift and leverage. A great bit for when you need lift and control.
This is a vulcanite covered metal bar with a stainless French style center link.
This bit is made off the Nathe RNF Kimberwick pattern pictured
