Monitor Brake Co

Monitor Brake Co., Limited Monitor Works, Birmingham England

“…best remembered today, if at all, for their odd cantilever/centerpull “Supercam” brake. They also made generic steel sidepulls, the Speedster, the Climax, and the Sheerline with its odd and flimsy looking (but patented!) riveted-on stirrup ends.”
