The Racing Dee Bit with Thick Hollow Mouth features a hollow mouthpiece that offers a unique combination of a heavy feel yet remains light and comfortable in the horse’s mouth. This design provides gentle and easy action, making it particularly suitable for soft-mouthed horses.

The bit is made of stainless steel and is available in various sizes, typically around 12.5 cm (5 inches) mouth length and a thick, approximately 20mm mouth thickness, which contributes to its lightweight feel despite the "heavy" sensation it imparts. Overall, it balances firmness with softness, promoting better control while ensuring the horse’s comfort.
