Merrill Bits Long Gag Chain Dogbone Roller

About the Bit

The Merrill Long Gag Bit with Chain Dogbone Roller Mouthpiece delivers powerful lift, clear communication, and a soft-flexing feel—all in one refined design. The long shank increases leverage for riders who need stronger elevation and more authority, while the chain-style mouthpiece keeps the bit comfortable and adaptable for a wide range of horses.

The Dogbone Roller encourages relaxation and focus, especially for horses that tend to get tight or busy in the mouth. This combination makes the bit both effective and forgiving, ideal for improving balance, elevating the front end, and sharpening responsiveness.
