Measurements: 5.5 cm length 2.5 cm wide About Troika: A troika (Russian:, "triplet" or "trio") is a traditional Russian harness driving combination, using three horses abreast, usually pulling a sleigh. It differs from most other three-horse combinations in that the horses are harnessed abreast. The middle horse is usually harnessed in a horse collar and shaft bow; the side horses are usually in breasts collar harness. The troika is traditionally driven so that the middle horse trots and the side horses canter; the right-hand horse will be on the right lead and the left-hand horse on the left lead.
