In a significant development within the cycling industry, Paragon Machine Works (PMW), a cornerstone in bicycle frame building components for over four decades, has announced its closure. The company cited “market and industry factors” as the primary reasons for ceasing major operations. Despite this, PMW will continue to operate with a reduced staff to sell existing inventory through their website and will manufacture parts until material supplies are exhausted, prioritising items with the highest demand.
Founded in 1983, Paragon Machine Works has been instrumental in providing high-quality, precision bicycle frame building components. Their products have been integral to the cycling community, supporting both professional and amateur builders in crafting custom frames. The company’s commitment to innovation and quality has earned it a loyal customer base over the years.
The decision to close comes after a period of significant change in the industry. In September 2025, Mirion Technologies, a global provider of radiation detection and monitoring solutions, announced the acquisition of Paragon Energy Solutions, a leading provider of engineering technology for the nuclear power industry, for approximately $585 million. (ans.org) While this acquisition pertains to the nuclear sector, it highlights the dynamic nature of industries and the challenges companies face in adapting to evolving market conditions.
The closure of Paragon Machine Works marks the end of an era for the cycling industry. Their products have been a staple for frame builders, and their absence will be felt across the community. As the industry continues to evolve, the legacy of Paragon Machine Works will remain a testament to quality and craftsmanship in bicycle frame building.
