Billy Allen bits are one of our absolute favorite bits! This one is new with tags from PROformance Saddles and Tack. 5″ mouth in a thinner diameter. 8.5″ shanks that are swept back, offering good pre-signal, almost in an Argentine/Loomis style. This one has a center roller and copper inlays. Billy Allen mouths are more mullen in nature, with a roller, that offers quite a bit of stability while still having some pick up. This one is new with tags.
