Abstract: A stirrup mounting device includes a stirrup attachment bar adapted for attachment to a stirrup strap loop extending from a saddle and a stirrup mounting bracket attached to a stirrup. The stirrup mounting bracket may be pivotally attached to the stirrup attachment bar so that the stirrup can rotate with respect to the stirrup strap loop about a vertical pivot axis. The vertical pivot axis is offset with respect to at least one of a vertical axis extending centrally through the stirrup strap loop and a vertical axis extending centrally through the stirrup so that the stirrup is offset toward the rear end of the stirrup attachment bar when the stirrup is rotated to a riding position. The stirrup mounting device can be used alone, or can be combined as part of a stirrup extender device where both the stirrup extender and the stirrup mounting device share a common stirrup attachment arm.
