The Acavallo Feeling Sensitive Bit is the best example of modern bit technology. Talk about a great option for a horse who is averse to metal in their mouths. A truly innovative design with a hypoallergenic plastic material that is over a flexible cable center. A very soft bit that is durable to marking and chewing, in a straight mullen style in a thinner diameter. This one is a great option for a horse who desires a bit less bulk to their bit. Shanked/Pelham style cheeks that have varying slots to allow for changes to rein and bridle placement to change the action of the bit, including offering leverage. This one is a 5” per tags, but we feel like it fits like a snug 5”, measuring 4 15/16”. Very light weight. New with tags!
