    Threaded or threadless headset? If it's threaded, measure the stem quill. 1" stems use 22.2mm diameter stems. 1 1/8" use 25.4mm stems. If it's threadless, take off the top cap and measure the inside diameter of the stem. If it's 25.4mm that's a 1". If it's 28.6mm that a 1 1/8" If its 31.8mm that's 1 1/4"

    Get a cheap set of calipers if you don't already have one.

    Contact HARO and ask them the spec for your frame?
