My horse is so picky when it comes to bits and I had tried all the “fad” bits going. He would still shake his face in the turns… in everything from an o ring to the most popular and expensive bits out there. I contacted the crew at Shallow creek bits as a last effort to find something he liked… and oh did they deliver! Not only did they make outstanding recommendations but my horse honestly loves this bit like nothing else I have put on him! We went from shaking our face in turns to be from the 2-4D to running consistently in the 1-2D at some big races in the northwest! I highly recommend if you have any questions contact them for advice before ordering!
