Our Story

Paragon Machine Works was founded in 1983 in Marin County, California, by owner Mark Norstad, in the basement of his parent's house with one manually operated lathe and mill. It has grown into a thriving machine shop, occupying an 8,000 square foot building in Richmond, California. Paragon Machine Works manufactures and stocks a wide variety of bicycle frame building components in titanium, steel, stainless steel, and aluminum. We are a leader in bicycle frame building technology, constantly innovating and providing new products to meet the demands of the industry and the needs of the frame builders. In addition we have manufactured parts for heavy equipment, solar, environmental remediation, and process equipment companies.

Mark Norstad
Company Founder and Owner

Mark Norstad

Mark's passion for machine work started in a high school machine shop class. He continued his professional development by completing an Associate of Arts Degree in Machine Metals Technology from College of Marin, California in 1979. Being an avid rider, it was only natural that his first production job was making dropouts for Trailmaster Bikes. Paragon Machine Works is now known for being the premier provider of precision bicycle components. Mark's skills have been refined over the years by completing complex design and manufacturing products for makers of bicycle frames, heavy off-road vehicles, process and alternative energy equipment. He credits his success to over twenty-five years of manufacturing experience, his passion for metal working, and a dedicated and knowledgeable staff.
