Product description
Tongue Relief and Clear Signals on a Stable Shank
Best for: Western riders looking for a Level 2 shank bit that gives some tongue relief and independent side signals.
The Myler MB 04 Comfort Snaffle with HBT Shank pairs Myler's low port comfort snaffle mouthpiece with the HBT shank, here in a 5 1/2 inch mouth. Myler rates the MB 04 mouthpiece as a Level 2 bit.
The mouthpiece is sweet iron with a copper inlay. Sweet iron oxidizes and encourages salivation, and the small 1/4 inch port introduces some tongue relief. The mouthpiece is curved, so it wraps around the bars and lips instead of pinching, and Independent Side Movement lets you lift one side without moving the other.
The HBT shank is about 5 inches of round metal, slightly curved back, with a flat-top purchase and a rein ring. The purchase angles slightly away from the horse to avoid rubbing, and the bit is used with a curb strap attached to the purchase.
