Cheekpiece: The Two Ring Gag offers a simpler, milder version of the adjustable-leverage gag concept — combining poll and mouth pressure with some lateral support — making it a popular choice for horses that need a bit more control than a snaffle provides (especially in eventing and jumping) without requiring the stronger, more graduated leverage of a three-ring gag.
Mouthpiece: A double-jointed blue steel mouthpiece with brass rollers combines three comfort- and acceptance-focused features: a flatter, gentler double joint (avoiding the nutcracker effect), blue steel's natural sweet taste (encouraging salivation and relaxation), and rollers (giving a fidgety tongue something to do) — making it a popular, mild-to-moderate mouthpiece choice for horses that need encouragement to relax, salivate, and accept contact comfortably, regardless of which cheek/ring style it's built onto.
